NOTE: During opening and closing of the feed and ash doors of this heater, it may seem that the t of the

door is "too tight". As the heater is red, the gasketing "settles" or "seats" itself in the door. The tight t at the

factory and before the heater's initial ring is to insure a good seal after the gasketing "settles".

SAFETY NOTICE

• If this stove is not properly installed, a house re may result. To reduce the risk of re, follow the installation

instructions.

• Consult your municipal building department or re ofcials about permits, restrictions and installations

requirements in your area.

• Use smoke detectors in the room where your stove is installed.

• Keep furniture and drapes well away from the stove.

• Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter uid, or similar liquids to start or

“freshen up” a re in this heater. Keep all such liquids well away from the heater while it is in use.

• In the event of a chimney re, push the air control full closed to deprive the re of oxygen. Call the re

department.

• Do not connect to any air distribution duct or system.

• A source of fresh air into the room or space heated shall be provided when required.

POSITIONING THE STOVE

It is very important to position the wood stove as close as possible to the chimney, and in an area that will favour

the most efcient heat distribution possible throughout the house. The stove must therefore be installed in the

room where the most time is spent, and in the most spacious room possible. Wood stoves produce radiating

heat, that is the heat we feel when we are close to a wood stove. A wood stove also functions by convection.

Convection is the displacement of hot air accelerated upwards and its replacement with cooler air. If necessary,

the hot air distribution from the stove may be facilitated by the installation of a blower.

The wood stove must not be hooked up to a hot air distribution system since an excessive accumulation of heat

may occur.

A wood stove must never be installed in a hallway or near a staircase, since it may block the way in case of re

or fail to respect required clearances.

INSTRUCTIONS FOR LATCH OPERATION

Follow these instructions to operate you unit safely when operating the

feed door.

1. Turn handle clockwise to the 12 o’clock position (A), pull the door

open until you engage the second step (B).

2. Hold the door in that position for approximately 10 seconds.

3. Then to open door, turn the handle counter clockwise to the 9 o’clock

position (C) and then continue to pull the door open. (D)

4. To close and latch the door, reverse steps 1 thru 4.

HOW TO OPEN THE TOP LID

CAUTION! DO NOT OPEN OR CLOSE THE TOP WHEN THE HEATER IS HOT!

To open, grasp the top at the front or on each corner and lift all the way up

until the support rod stops the motion. Then gently lower the top allowing the

support rod to settles in the cup, holding the top open.

To Close, lift the top until the support rod is out of the cup. Pull the rod forward

and lower the lid closed.

THERMODISC KIT FOR B36 BLOWER - OPTIONAL

Wish your blower would turn ON and OFF as the heater gets warm and cold?

It can with this optional kit from U.S. Stove. It connects in line with your power

supply cord and mounts to the back of the heater. When the snap disc

reaches 120 degrees, the blower automatically turns ON and turns itself OFF

if it reaches 90 degrees. See your Dealer for details or call U.S. Stove directly.

CLEARANCES TO COMBUSTIBLES

It is of utmost importance that the clearances to combustible materials be strictly adhered to during installation

of the stove. Refer to the tables below.

• Floor to ceiling height must be at least 7’ (2.13m) in all cases.

• Do not place any combustible material within 4’ (1.2m) of the front of the unit.

• The clearance between the ue pipe and a wall are valid only for vertical walls and for vertical ue pipe.

• The chimney connector must not pass through an attic or roof space, closet or similar concealed space, a

oor, or a ceiling.

• For Canadian installations, where passage through a wall, or partition of combustible construction is desired,

the installation must conform to CAN/CSA-B365.

• A ue pipe crossing a combustible wall must have a minimum clearance of 18” (457.2mm).

• To reduce ue clearances from combustible materials, contact your local safety department.

• The provision that clearances may only be reduced by means approved by regulatory authority

CHIMNEY CONNECTOR (STOVE PIPE)

Your chimney connector and chimney must have the same diameter as the stove outlet (6”). If this is not the

case, we recommend you contact your dealer in order to insure there will be no problem with the draft.

The stove pipe must be made of aluminized or cold roll steel with a minimum thickness of 0.021” or 0.53 mm. It is

strictly forbidden to use galvanized steel.

Your smoke pipe should be assembled in such a way that the male section (crimped end) of the pipe faces

down. Attach each of the sections to one another with three equidistant metal screws.

The pipe must be short and straight. All sections installed horizontally must slope at least 1/4 inch per foot, with

the upper end of the section toward the chimney. Any installation with a horizontal run of chimney pipe must

conform to NFPA 211. You may contact NFPA (National Fire Protection Association) and request the latest edition

of the NFPA Standard 211.

To insure a good draft, the total length of the coupling pipe should never exceed 8’ to 10’ (2.4m to 3.04 m).

(Except for cases of vertical installation, cathedral-roof style where the smoke exhaust system can be much

longer and connected without problem to the chimney at the ceiling of the room).

There should never be more than two 90 degrees elbows in the smoke exhaust system.

Installation of a “barometric draft stabilizer” (replace register) on a smoke exhaust system is prohibited.

Furthermore, installation of a draft damper is not recommended. Indeed, with a controlled combustion wood

stove, the draft is regulated upon intake of the combustion air in the stove and not at the exhaust.

IMPORTANCE OF PROPER DRAFT

Draft is the force which moves air from the appliance up through the chimney. The amount of draft in your

chimney depends on the length of the chimney, local geography, nearby obstructions and other factors. Too

much draft may cause excessive temperatures in the appliance. Inadequate draft may cause backpufng into

the room and ‘plugging’ of the chimney. Inadequate draft will cause the appliance to leak smoke into the room

through appliance and chimney connector joints. An uncontrollable burn or excessive temperature indicates

excessive draft.

CHIMNEY

Take into account the chimney’s location to insure it is not too close to neighbours or in a valley which may

cause unhealthy or nuisance conditions. Your wood stove may be hooked up with a 6” factory built or masonry

chimney. If you are using a factory built chimney, it must comply with UL 103 or CSA-B365 standard; therefore it must

be a Type HT (2100°F). It is extremely important that it be installed according to the manufacturer’s specications.

If you are using a masonry chimney, it is important that it be built in compliance with the specications of the

National Building Code. It must be lined with re clay bricks, metal or clay tiles sealed together with re cement.

(Round ues are the most efcient).

The interior diameter of the chimney ue must be identical to the stove smoke exhaust. A ue which is too

small may cause draft problems, while a large ue favours rapid cooling of the gas, and hence the build-up of

creosote and the risk of chimney res. Note that it is the chimney and not the stove which creates the draft effect;

your stove’s performance is directly dependent on an adequate draft from your chimney.

The following recommendations may be useful for the installation of your chimney:

1. Do not connect this unit to a chimney ue serving another appliance.

2. It must rise above the roof at least 3’ (0.9m) from the uppermost point of contact.

3. The chimney must exceed any part of the building or other obstruction within a 10’ (3.04m) distance by a

height of 2’ (0.6m).

4. Installation of an interior chimney is always preferable to an exterior chimney. Indeed, the interior chimney

will, by denition, be hotter than an exterior chimney, being heated up by the ambient air in the house.

Therefore the gas which circulates will cool more slowly, thus reducing the build-up of creosote and the risk

of chimney res.

5. The draft caused by the tendency for hot air to rise will be increased with an interior chimney.

6. Using a re screen at the extremity of the chimney requires regular inspection in order to insure that it is not

obstructed thus blocking the draft, and it should be cleaned when used regularly.

FACTORY BUILT CHIMNEY

When a metal prefabricated chimney is used, the manufacturer’s installation instructions must be followed. You

must also purchase (from the same manufacturer) and install the ceiling support package or wall pass-through

and “T” section package, restops (where needed), insulation shield, roof ashing, chimney cap, etc. Maintain

proper clearance to the structure as recommended by the manufacturer. The chimney must be the required

height above the roof or other obstructions for safety and proper draft operation.

MASONRY CHIMNEY

Ensure that a masonry chimney meets the minimum standards of the National Fire Protection Association (NFPA)

by having it inspected by a professional. Make sure there are no cracks, loose mortar or other signs of deterioration

and blockage. Have the chimney cleaned before the stove is installed and operated. When connecting the

stove through a combustible wall to a masonry chimney, special methods are needed.

COMBUSTIBLE WALL CHIMNEY CONNECTOR PASS-THROUGHS

Method A. 12” (304.8 mm) Clearance to Combustible Wall

Member: Using a minimum thickness 3.5” (89 mm) brick and a

5/8” (15.9 mm) minimum wall thickness clay liner, construct a

wall pass-through. The clay liner must conform to ASTM C315

(Standard Specication for Clay Fire Linings) or its equivalent.

Keep a minimum of 12” (304.8 mm) of brick masonry between

the clay liner and wall combustibles. The clay liner shall run

from the brick masonry outer surface to the inner surface of the

chimney ue liner but not past the inner surface. Firmly grout or

cement the clay liner in place to the chimney ue liner.

Method B. 9” (228.6 mm) Clearance to Combustible Wall

Member: Using a 6” (152.4 mm) inside diameter, listed, factory-

built Solid-Pak chimney section with insulation of 1” (25.4 mm) or

more, build a wall pass-through with a minimum 9” (228.6 mm)

air space between the outer wall of the chimney length and

wall combustibles. Use sheet metal supports fastened securely

to wall surfaces on all sides, to maintain the 9” (228.6 mm) air

space. When fastening supports to chimney length, do not

penetrate the chimney liner (the inside wall of the Solid-Pak

chimney). The inner end of the Solid-Pak chimney section shall

be ush with the inside of the masonry chimney ue, and sealed

with a non-water soluble refractory cement. Use this cement to

also seal to the brick masonry penetration.

Method C. 6” (152.4 mm) Clearance to Combustible Wall

Member: Starting with a minimum 24 gage (.024” [.61 mm])

6” (152.4 mm) metal chimney connector, and a minimum 24

gage ventilated wall thimble which has two air channels of 1”

(25.4 mm) each, construct a wall pass-through. There shall be a

minimum 6” (152.4) mm separation area containing berglass

insulation, from the outer surface of the wall thimble to wall

combustibles. Support the wall thimble, and cover its opening

with a 24-gage minimum sheet metal support. Maintain the 6”

(152.4 mm) space. There should also be a support sized to t

and hold the metal chimney connector. See that the supports

are fastened securely to wall surfaces on all sides. Make sure

fasteners used to secure the metal chimney connector do not

penetrate chimney ue liner.

Method D. 2” (50.8 mm) Clearance to Combustible Wall

Member: Start with a solid-pak listed factory built chimney

section at least 12” (304 mm) long, with insulation of 1” (25.4

mm) or more, and an inside diameter of 8” (2 inches [51 mm]

larger than the 6” [152.4 mm] chimney connector). Use this as a

pass-through for a minimum 24-gauge single wall steel chimney

connector. Keep solid-pak section concentric with and spaced

1” (25.4 mm) off the chimney connector by way of sheet

metal support plates at both ends of chimney section. Cover

opening with and support chimney section on both sides with

24 gage minimum sheet metal supports. See that the supports

are fastened securely to wall surfaces on all sides. Make sure

fasteners used to secure chimney ue line.

NOTES:

1. Connectors to a masonry chimney, excepting method B, shall extend in one continuous section through the

wall pass-through system and the chimney wall, to but not past the inner ue liner face.

2. A chimney connector shall not pass through an attic or roof space, closet or similar concealed space, or a

oor, or ceiling.

It is EXTREMELY IMPORTANT that you use DRY WOOD only in your wood stove. The wood should have dried for 9

to 15 months, such that the humidity content (in weight) is reduced below 20% of the weight of the log. It is very

important to keep in mind that even if the wood has been cut for one, two or even more years, it is not necessarily

dry, if it has been stored in poor conditions. Under extreme conditions it may rot instead of drying. This point

cannot be over stressed; the vast majority of the problems related to the operation of a wood stove is caused by

the fact that the wood used was too damp or had dried in poor conditions. These problems can be:

- ignition problems

- creosote build-up causing chimney res

- low energy yield

- blackened windows

- incomplete log combustion

WOODSTOVE UTILIZATION

This heater is designed to burn natural wood only. Higher efciencies and lower emissions generally result when

burning air dried seasoned hardwoods, as compared to softwoods or to green or freshly cut hardwoods.

DO NOT BURN:

1. Garbage;

2. Lawn clippings or yard waste;

3. Materials containing rubber, including tires;

4. Materials containing plastic;

5. Waste petroleum products, paints or paint thinners,

or asphalt products;

6. Materials containing asbestos;

7. Construction or demolition debris;

8. Railroad ties or pressure-treated wood;

9. Manure or animal remains;

10. Salt water driftwood or other previously salt water

saturated materials;

11. Unseasoned wood; or

12. Paper products, cardboard, plywood, or

particleboard. The prohibition against burning

these materials does not prohibit the use of re

starters made from paper, cardboard, saw dust,

wax and similar substances for the purpose of

starting a re in an affected wood heater.

Burning these materials may result in release of toxic fumes or render the heater ineffective and cause smoke.

Dead wood lying on the forest oor should be considered wet, and requires full seasoning time. Standing dead

wood can usually be considered to be about 2/3 seasoned. Splitting and stacking wood before it is stored

accelerates drying time. Storing wood on an elevated surface from the ground and under a cover or covered

area from rain or snow also accelerates drying time. A good indicator if wood is ready to burn is to check the

piece ends. If there are cracks radiating in all directions from the center then the wood should be dry enough

to burn. If your wood sizzles in the re, even though the surface is dry, it may not be fully cured, and should be

seasoned longer. Waste and other ammable materials should not be burned in your stove.

Do not burn manufactured logs made of wax impregnated sawdust or logs with any

chemical additives. Manufactured logs made of 100% compressed sawdust can be

burned, but be careful burning too much of these logs at the same time. Start with

one manufactured log and see how the stove reacts. You can increase the number

of logs burned at a time to making sure the temperature never rises higher than 475

°F (246 °C) on a magnetic thermometer for installation on single wall stove pipes or

900 °F (482 °C) on a probe thermometer for installation on double wall stove pipe.

The thermometer should be placed about 18” (457 mm) above the stove. Higher

temperatures can lead to overheat and damage your stove. Any type of wood may

be used in your stove, but specic varieties have better energy yields than others.

Please consult the following table in order to make the best possible choice.

Smaller pieces of wood will dry faster. All logs exceeding 6” in diameter should be split. The wood should not be

stored directly on the ground. Air should circulate through the cord. A 24” to 48” air space should be left between

each row of logs, which should be placed in the sunniest location possible. The upper layer of wood should be

protected from the elements but not the sides.

OPERATIONAL TIPS

• Operational Tips for Good, Efcient, and Clean Combustion

• Get the appliance hot and establish a good coal bed before

adjusting to a low burn rate (this may take 30 minutes or more

depending on your wood)

• Use smaller pieces of wood during start-up and a high burn rate

to increase the stove temperature

• Be considerate of the environment and only burn dry wood

• Burn small, intense res instead of large, slow burning res when

possible

• Learn your appliance’s operating characteristics to obtain

optimum performance

Burning unseasoned wet wood only hurts your stoves efciency and

leads to accelerated creosote buildup in your chimney. The clean

outs are secured to the rebox with (2) 5/16” screws. Remove the

clean outs and vacuum out any accumulated ash. This should be

done at least once per month or more frequently if large amounts of

ash are noticed while cleaning or if the stove does not seem to be

burning properly. The ring and ash doors must be closed and sealed

during operation.

TESTING YOUR WOOD

When the stove is thoroughly warmed, place one piece of split wood (about ve inches in diameter) parallel to

the door on the bed of red embers.

Keep the air control full open by pulling on it and close the door. If ignition of the piece is accomplished within

90 seconds from the time if was placed in the stove, your wood is correctly dried. If ignition takes longer, your

wood is damp.

If your wood hisses and water or vapor escapes at the ends of the piece, your wood is soaked or freshly cut.

Do not use this wood in your stove. Large amounts of creosote could be deposited in your chimney, creating

potential conditions for a chimney re.

TAMPER WARNINGS

This wood heater has a manufacturer-set minimum low burn rate that must not be altered. It is against federal

regulations to alter this setting or otherwise operate this wood heater in a manner inconsistent with operating

instructions in this manual.

THE FIRST FIRES

The fresh paint on your stove needs to be cured to preserve its quality. Once the fuel charge is properly ignited,

only burn small res in your stove for the rst four hours of operation. Never open the air control more than

necessary to achieve a medium burn rate.

Make sure that there’s enough air circulation while curing the stove. The odors could be smelled during the 3 or

4 rst res. Never start your stove outside. You will not be able to see if you are over heating.

IGNITION

The top down method of re building is recommended for this appliance. Place the largest pieces of wood on

the bottom, laid in parallel and close together. Smaller pieces are placed in a second layer, crossways to the

rst. A third layer of still smaller pieces is laid crossways to the second, this time with some spaces between. Then

a fourth layer of loose, small kindling and twisted newspaper sheets tops off the pile.

CAUTION: Never alter the damper slide or the adjustment range to increase ring for any reason. Doing so

could result in heater damage and will void your warranty.

Air

Cleanouts

Before igniting the paper and kindling wood, it is recommended that you warm up the chimney. This is done

in order to avoid back draft problems often due to negative pressure in the house. If such is the case, open a

window slightly near the stove and twist together a few sheets of newspaper into a torch. Light up this paper

torch and hold it as close as possible to the mouth of the pipe inside the combustion chamber to warm up the

chimney. Once the up-draft movement is initiated, you are ready to ignite the stove by lighting the paper and

kindling wood inside the combustion chamber.

POSSIBLE FLUE OR CHIMNEY DEFECTS

From the foregoing basic principles for the regulation of chimney ues, it will be seen that unsatisfactory stove

operation may be the result of any of the following possible chimney ue defects:

1. Insufcient height.

2. Surrounding nearby objects throwing air currents down the chimney.

3. Flues enlarged or contracted at some point.

4. Rubbish or soot obstruction in the ue.

5. Air leakage in cracks where mortar has fallen out.

6. Floor support or a pipe passing through or entering the ue.

7. Too abrupt offsets.

8. Other connecting ues

9. Chimney being used for ventilating basement

10. Chimneys too large for stove being used.

11. Flues being long and narrow

12. More than one smoke-pipe connected to the ue.

13. Chimney connector protruding too far into the chimney.

FUEL

Seasoned cordwood will give the most heat. Your heater will burn most any type of cordwood. Seasoned

hardwood produces more heat, and will hold a re longer, leaving a hotter coal bed than seasoned softwood.

Coal should never be used in a heater designed for burning wood. Never use driftwood that has been in salt water.

The salt content will cause corrosion that will destroy the stainless steel in the Class A chimney, the ue connector

and the rebox. Hard wood cut to 20” maximum length, and split 3” to 6” cross section is recommended for best

operating efciency. CAUTION: Burn untreated cordwood only. Wood containing preservative, metal foils, coal,

plastic, garbage, sulphur or oil is environmentally hazardous and will damage the appliance.

LOADING OF FUEL

Do not overll the rebox above the rebrick. Wood should be 3 to 4” below top of rebrick. A burned-out heat

chamber may result. Do not use articial or wax logs. Build re on the oor of the stove. Do not use additional

grates or andirons to support the re as these may create excessive heat. For the most heat, combustion air must

be able to circulate around and through the re. Do not block the air entrances inside the rebox with ashes.

When loading each additional fuel charge, clear the ashes away from the lower primary air orices behind the

bottom of the door opening.

PREPARATION AND STORAGE OF FUEL

Solid fuel should be cut and split prior to the heating season and stored in a well, aired dry place. Do not store

fuel within the room heater clearances or within the space required for fuelling or ash removal. Fuel should be

kept at least 5ft clear (1.5m) from the heater. The space around the heater should be kept free of litter and wood

residue.

TYPES OF COMBUSTION AIR FOR WOOD HEATING

Unlike older airtight box stoves, low emission woodstoves have more than one location and control for supplying

combustion air into the rebox. These additional air inlets allow for complete combustion of wood gases and

particulates. Thus it is important to understand how these different air supplies work. PRIMARY AIR starts the re.

Opening or closing this air supply then regulates how fast the stove will burn. Primary air is supplied by the following:

a dial with settings for burn rates and a thermostat. Use the Primary Air Control (PAC) dial (on right) to control the

burn. Adjust the settings to obtain the desired heat output. Always start a re with the PAC set on high and leave

it on high until the secondary ames continue to burn after the PAC has been adjusted to a lower setting. Reset

the PAC to high when reloading. The thermostat also controls the amount of primary air entering the unit. Set it

on “Open” when starting a re and leave it on “Open” until the stove has been burning long enough to keep the

secondary ames burning when it is closed. Set the thermostat on “Open” for 10 to 20 minutes when reloading.

It is very important to keep the secondary ames burning to maximize heat output and minimize air pollution, so

some experimentation will be necessary because each installation is different. Wood moisture content will also

affect the amount of time that a unit will need to burn on high after each reload.

SECONDARY AIR allows the woodstove to burn clean. This preheated air enters the upper rebox just below

the bafe plate. This superheated air mixed with the wood gases and ames ignites, reaching temperatures in

this unit range. Without Secondary Air these volatile gases would exit the stove unburned as creosote, smoke,

particulates, and high levels of Carbon Monoxide, greatly decreasing efciency. Heat comes from burning the

wood gases, not the wood, which itself turns into black charcoal after the gases are all released. Secondary air

increases a stoves efciency by approximately 40% greatly reducing the amount of wood required for a heating

season (easily up to 1/3 less wood).

Secondary air timer (SAT) located on the left side of this appliance. Never attempt to burn your stove with the

timer knob set in the off position. This closes Off the secondary air and your stove will burn dirty and produce

creosote. The SAT should be left in the open position and locked with the timer stop lever set on

“Hi” and your stove will burn optimally. It is not necessary to use the timer except if you Wish to extend the length

of the coal bed time, after the wood has nished burning The Secondary Air Timer (SAT) is used to control the

duration of secondary air entering the stove. When burning the stove be sure the timer is set to open (Timer Knob

past One Hour and Timer Lever to “HI”. The SAT is only used if you wish to extend the coal bed time on Medium

Low or Low setting. To do so:

1. GENTLY rotate Timer Knob clockwise to 2.5 to 3 hours for

Medium Low and 3 to 3.5 hours for Low as designated

on the timer plate.

2. Turn the timer lever down to ”LO” to allow the timer

to close. Observe that the timer closes after there

are no more ames present

3. THE TIMER MUST BE OPENED AND THE LEVER SET TO

“HI” BEFORE ADDING MORE FUEL.

4. The above settings are based upon a 15 foot

chimney. The actual settings may vary slightly due to

your chimney height and the outside temperatures.

Taller chimneys and colder outside temperatures

cause a stove to burn faster. This means the SA timer

does not have to be opened as long. The same is

true of wood moisture – drier fuel will burn faster than

wetter fuel.

TIMER INSTRUCTIONS

The timer assembly on this unit requires periodic maintenance to ensure proper operation. Locate the timer on

the left-hand side of the appliance, then follow the steps below to facilitate the annual cleaning of the timer

assembly.

STEP 2

STEP 1

CAUTION: Allow the stove to cool

completely before carrying out

any maintenance or cleaning

STEP 3

Using a canned air duster, gently

spray any accumulative dust or

buildup off of the timer.

STEP 4

Use a general machine oil (3-IN-ONE) to apply

a small drop of oil to each of the locations

shown below.

To reassemble the timer simply reverse the

previous steps. Ensure proper operation before

attaching the nal cover plate.

LIGHTING AND OPERATION

1. IMPORTANT! – NEVER OPERATE THIS

WOODSTOVE WITHOUT THE SECONDARY

AIR TIMER IN THE LOCKED OPEN POSITION

WHEN LIGHTING A FIRE OR RELOADING!

2. Set the PAC dial and the thermostat on

HIGH to provide maximum draft.

3. Note that the Secondary Air Inlet is in the”

LOCKED OPEN POSITION” on the left side of

the stove.

4. Open loading door and lay re, using

ample kindling to ensure rapid ignition.

5. Prime chimney if necessary holding lighted newspaper up towards ue bafe. A CANDLE WORKS BEST AND

WILL NOT SMOKE UP THE ROOM IF THE COLD AIR BLOWS THE NEWSPAPER OUT.

6. Light re and close loading door.

7. Wait 3 - 5 minutes then add seasoned rewood. (See section concerning Fuel).

8. Set the PAC dial to maintain desired temperature in room. Medium setting is normally satisfactory. Set high

or lower for desired temperature.

9. Once re is established set the Burn Rate dial to the desired rate. This will maintain a steady temperature after

the thermostat closes.

CAUTION: Do not operate this heater with the loading door open. Continuous operation with a door open will

over heat the unit. This heater is designed for Thermostatic and Burn Rate Dial operation.

THERMOSTAT ADJUSTMENT DIAL

The adjustment plate in the thermostat may be set to change the burn rate. Open to increase and close to

decrease burn rate. Leave adjustment for a few days after changing to see if burn rate is better for your situation.

REFUELLING

CAUTION: Read the section on back-pufng before refuelling heater. The loading door should be closed at all

times except when refuelling. If the door is allowed to remain open, the thermostat will not function, as it should.

Before opening the loading door, make sure the thermostat is open. Allow the re to burn rather briskly for a

few minutes. Then open the loading door slowly. By allowing the re to increase for a short period, a high draft

condition has eliminated smoke in the rebox and the temperature has been raised which prevents a back

or down draft. After refueling, run the dial on High and thermostat on open for 10 to 30 minutes to insure the

secondaries ignite and stay lit when the air controls are adjusted to the desired settings. Keeping the secondaries

lit is important for two reasons:

1. More heat is obtained from the wood

2. Smoke is particulate matter which is air pollution

WARNING:

Be careful not to use too much

air pressure as this may cause

potential damage to the timer

HEATING

Controlled combustion is the most efcient technique for wood heating because it enables you to select the type

of combustion you want for each given situation. The wood will burn slowly if the wood stove air intake control is

adjusted to reduce the oxygen supply in the combustion chamber to a minimum. On the other hand, wood will

burn quickly if the air control is adjusted to admit a larger quantity of oxygen in the combustion chamber. Real

operating conditions may give very different results than those obtained during testing according to the species

of wood used, its moisture content, the size and density of the pieces, the length of the chimney, altitude and

outside temperature.

EFFICIENCY

Efciencies can be based on either the lower heating value (LHV) or the higher heating value (HHV) of the fuel.

The lower heating value is when water leaves the combustion process as a vapor, in the case of woodstoves the

moisture in the wood being burned leaves the stove as a vapor. The higher heating value is when water leaves

the combustion process completely condensed. In the case of woodstoves this would assume the exhaust gases

are room temperature when leaving the system, and therefore calculations using this heating value consider

the heat going up the chimney as lost energy. Therefore, efciency calculated using the lower heating value of

wood will be higher than efciency calculated using the higher heating value. In the United States all woodstove

efciencies should be calculated using the higher heating value. The best way to achieve optimum efciencies

is to learn the burn characteristic of you appliance and burn well-seasoned wood. Higher burn rates are not

always the best heating burn rates; after a good re is established a lower burn rate may be a better option for

efcient heating. A lower burn rate slows the ow of usable heat out of the home through the chimney, and it

also consumes less wood.

VISIBLE SMOKE

The amount of visible smoke being produced can be an effective method of determining how efciently the

combustion process is taking place at the given settings. Visible smoke consist of unburned fuel and moisture

leaving your stove. Learn to adjust the air settings of your specic unit to produce the smallest amount of visible

smoke. Wood that has not been seasoned properly and has a high wood moisture content will produce excess

visible smoke and burn poorly.

CREOSOTE FORMATION AND NEED FOR REMOVAL

When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture

to form creosote. The creosote vapors condense in the relatively cool chimney ue of a slow-burning re. As a

result, creosote residue accumulates on the ue lining. When ignited this creosote makes an extremely hot re.

The chimney connector and chimney should be inspected at least once every two months during the heating

season to determine if a creosote build-up has occurred. If creosote has accumulated (3mm or more), it should

be removed to reduce the risk of a chimney re. We strongly recommend that you install a magnetic thermometer

on your smoke exhaust pipe, approximately 18” above the stove. This thermometer will indicate the temperature

of your gas exhaust fumes within the smoke exhaust system. The ideal temperature for these gases is somewhere

between 275°F and 500°F. Below these temperatures, the build-up of creosote is promoted. Above 500 degrees,

heat is wasted since a too large quantity is lost into the atmosphere.

TO PREVENT CREOSOTE BUILD UP

• Always burn dry wood. This allows clean burns and higher chimney temperatures, therefore less creosote

deposit.

• Leave the air control full open for about 5 min. every time you reload the stove to bring it back to proper

operating temperatures. The secondary combustion can only take place if the rebox is hot enough.

• Always check for creosote deposit once every two months and have your chimney cleaned at least once a

year.

WARNING:

• Never over re your stove. If any part of the stove starts to glow red, over ring is happening. Readjust the

air intake control at a lower setting.

• The installation of a log cradle or grates is not recommended in your wood stove. Build re directly on

rebrick.

• Never put wood above the rebrick lining of the rebox.

• Attempts to achieve heat output rates that exceed heater design specications can result in permanent

damage to the heater.

If a chimney or creosote re occurs, close all dampers immediately. Wait for the re to go out and the heater to

cool, then inspect the chimney for damage. If no damage results, perform a chimney cleaning to ensure there is

no more creosote deposits remaining in the chimney.

ASH DISPOSAL

Whenever ashes get 3 to 4 inches deep in your rebox or ash pan, and when the re has burned down and

cooled, remove excess ashes. Leave an ash bed approximately 1 inch deep on the rebox bottom to help

maintain a hot charcoal bed. Ashes should be placed in a metal container with a tight-tting lid. The closed

container of ashes should be placed on a noncombustible oor or on the ground, away from all combustible

materials, pending nal disposal. The ashes should be retained in the closed container until all cinders have

thoroughly cooled.

SMOKE AND CO MONITORS

Burning wood naturally produces smoke and carbon monoxide(CO) emissions. CO is a poisonous gas when

exposed to elevated concentrations for extended periods of time. While the modern combustion systems in

heaters drastically reduce the amount of CO emitted out the chimney, exposure to the gases in closed or conned

areas can be dangerous. Make sure your stove gaskets and chimney joints are in good working order and sealing

properly to ensure unintended exposure. It is recommended that you use both smoke and CO monitors in areas

having the potential to generate CO.

MAINTENANCE

Your wood stove is a high efciency stove and therefore requires little maintenance. It is important to perform

a visual inspection of the stove every time it is emptied, in order to insure that no parts have been damaged,

in which case repairs must be performed immediately. Inspect and clean the chimney and connector pipe

periodically for creosote build-up or obstructions.

GASKETING

This unit’s door uses a 1 inch diameter rope gasket. It is recommended that you change the door gasket (which

makes your stove door air tight) once a year, in order to insure good control over the combustion, maximum

efciency and security. To change the door gasket, simply remove the damaged one. Carefully clean the

available gasket groove, apply a high temperature silicone sold for this purpose, and install the new gasket. You

may light up your stove again approximately 24 hours after having completed this operation.

PAINT

Only clean your stove with a dry soft cloth that will not harm the paint nish. If the paint becomes scratched or

damaged, it is possible to give your wood stove a brand new look, by repainting it with a 1200° F heat resistant

paint. For this purpose, simply scrub the surface to be repainted with ne sand paper, clean it properly, and apply

thin coats (2) of paint successively.

Attention:

This wood heater needs periodic inspection and repair for proper operation. It is against federal regulations

to operate this wood heater in a manner inconsistent with operating instructions in this manual.

CAUTIONS:

• Ashes could contain hot embers even after two days without operating the stove.

• The ash pan can become very hot. Wear gloves to prevent injury.

• Never burn the stove with the ash trap open. This would result in over ring the stove. Damage to the stove

and even house re may result.

WARNING:

Never operate the stove without a gasket or with a broken one

Damage to the stove or even house re may result
