Rules for safe installation and operation
Read these rules and the instructions carefully. Failure to follow them will cause a hazard
that could result in death, serious bodily injury, and/or property damage.
Your Furnace is designed to be installed in a parallel air ow arrangement with a gas or oil-red
forced air upow-type central furnace, or it may be installed as a central furnace.
1. Check your local codes. The installation must comply
with their rulings.
2. Do not install this furnace in a mobile home or trailer.
3. Always connect this furnace to a chimney and vent to the
outside. Never vent to another room or inside a building.
4. Do not connect this furnace to an aluminum Type B gas
vent. This is not safe and is prohibited by the National
Fire Protection Association Code. This furnace requires
a masonry or Listed Factory Built Chimney for residential
type or Building Heating Appliance Chimney. Use a 6"
diameter chimney or larger, that is high enough to give
a good draft.
5. Be sure that if a masonry chimney is used, it is safely
constructed and in good repair. Have the chimney in-
spected by the Fire Department or an inspector.
6. Inspect chimney connector and chimney before and
frequently during the heating season for any deposit of
creosote or soot which must be removed.
7. Provide air for combustion into the room where the furnace
is located. If the intake is not in the same room, air must
have free access to the room.
8. CAST IRON PARTS MUST BE "SEASONED" TO AVOID
CRACKING, BUILD ONLY SMALL FIRES ON FIRST
USE.
9. To prevent injury, do not allow anyone to use this furnace
who is unfamiliar with the correct operation of the furnace.
10. For further information on using your furnace safely, obtain
a copy of the National Fire Protection Association (NFPA)
publication "Chimney's, Fireplaces and Solid Fuel Burn-
ing Appliances" NFPA 211. The address of the NFPA is
Batterymarch Park, Quincy, MA 02269.
11. Keep the ashpit section free of excess ashes. Do not al-
low ashes to stack higher than the sides of the ash pan.
12. DISPOSAL OF ASHES- Place ashes in a metal container
with a tight tting lid. Keep the closed container on a
noncombustible oor or on the ground, well away from
all combustible materials. Keep the ashes in the closed
container until all cinders have thoroughly cooled. The
ashes may be buried in the ground or picked up by a
refuse collector.
13. CAUTION- The special paints used on your furnace
may give off some smoke while they are curing during
rst few res., Build small res at rst. The metal used
in construction of the furnace and duct work has a light
coating of oil. This could give off smoke and/or odor from
registers when furnace is used for the rst time. This
should disappear after a short period of time. Once this
burn-off has occurred, it should not reoccur.
14. CARING FOR PAINTED PARTS- This furnace has a
painted outside jacket, which is durable, but it will not
stand rough handling or abuse. When installing your
furnace, use care in handling. Clean with soap and
warm water when furnace in not hot. DO NOT use any
acids or scouring soap, as these wear and dull the nish.
DISCOLORATION WILL OCCUR IF THE FURNACE IS
OVERHEATED. FOLLOW OPERATING INSTRUCTIONS
CAREFULLY.
15. Keep the feed and ash doors closed at all times except
while tending the furnace.
CAUTION
DO NOT OPERATE WITH THE FEED AND/OR ASH
DOOR OPEN. THIS FURNACE IS DESIGNED FOR
THERMOSTATIC OPERATION. OPERATION WITH
ANY OF THESE DOORS OPEN WILL OVERHEAT
AND DAMAGE THE FURNACE.
WARNING
NEVER STORE FLAMMABLE LIQUIDS, ESPECIALLY
GASOLINE, IN THE VICINITY OF THE FURNACE.
CAUTION
GASES THAT ARE DRIVEN FROM FRESH COAL
MUST BE BURNED OR THEY WILL ACCUMULATE
AND EXPLODE. NEVER SMOTHER A FIRE WHEN
ADDING FRESH COAL.
CAUTION
NEVER USE GASOLINE, GASOLINE-TYPE LAN-
TERN FUEL, KEROSENE, CHARCOAL LIGHTER
FLUID, OR FLAMMABLE LIQUIDS TO START OR
"FRESHEN UP" A FIRE IN THE FURNACE.

Your HOTBLAST Furnace is designed to be a supplemental or
central heating source for your home. This Solid Fuel Furnace
may be installed in conjunction with a properly operating
central furnace that is listed or certied in accordance with
nationally recognized safety standards and equipped with
the required controls and other safety features and which
has been installed in accordance with appropriate standards
of the National Fire Protection Association with installation
clearances specied in the furnace nameplate marking. The
installation must be accomplished by a qualied agency (one
who is engaged in, and is responsible for, or is thoroughly
familiar with the installation and operation of the gas, oil, and
solid fuel burning heating appliances, who is experienced in
such work, familiar with all the requirements of the authority
having jurisdiction.) The installation shall be in strict accordance
with the manufacturer's installation instructions furnished with
the solid fuel furnace.
The chimney connector of the furnace is to be installed to
provide clearances to combustible material not less than
specied in the individual classications and marked on the
furnace. The chimney connector must be connected to a
chimney suitable for use with residential type or building
heating appliances which burn solid fuel.
The Furnace is designed to operate in either parallel or series
air ow arrangement with the central furnace or as a central
furnace.
CENTRAL FURNACE INSTALLATION
As a central furnace, the unit functions independently of any
other system. The blower will come on when the plenum
temperature reaches the setting on the blower control.
PARALLEL INSTALLATION (U.S. ONLY)
The design is such that when the blower comes on, the blower
on the central system also comes on. The blower will only
come on when the temperature in the plenum has reached
the setting on the blower control. This is to insure that there
is sufcient warm air in the system to make it efcient for the
unit to operate. When the central system thermostat calls for
heat, the central system will operate by the burner igniting
and the blower coming on. It is possible that both systems
will operate simultaneously. It is recommended that for the
most efcient use of your HOTBLAST Furnace, that it be red
as much as possible in order to reduce the demand on your
existing central heating system. This unit has an optional
forced draft kit that operates from a wall thermostat. When
the temperature falls below the setting on the wall thermostat,
the forced draft will come on (U.S. Stove Option 11/DIKL)
The warm air supply outlet of the HOTBLAST Furnace shall
not be connected to the cold air return of the central furnace,
because the possibility exists of components of the central
furnace overheating and causing the central furnace to operate
other than is intended.
SERIES INSTALLATION
This type of installation uses only the blowers of the existing
central furnace. The solid fuel fan/limit control must also
control the functions of the existing furnace. All electrical
power must come from a single branch circuit.

LOCATING THE FURNACE
1. The furnace should be located in the same room as the
central system and as close as possible, but not closer than
9". There should be no wall between the furnace and the
warm air outlet duct that is connected directly to the warm
air outlet plenum of the central furnace. (See Fig. 4)
2. Place the furnace on a noncombustible oor.
3. Check gures 3 through 5. Be sure you have the clearances
shown below from the furnace and the connector pipe to
combustible surfaces. If you have a solid brick or stone wall
behind your furnace, you can place the furnace as close as
you wish to the wall. If the wall is only faced with brick or
stone, treat it as a combustible wall.

Chimney Connection
MASONRY CHIMNEY
Before using an existing masonry chimney, clean the chimney
and inspect the ue liner to be sure it is safe to use. Make repairs
before attaching the furnace. The connector pipe and ttings you
will need to connect directly to a masonry chimney are shown.
The chimney connection should be as short as possible.
If the connector pipe must go through a combustible wall before
entering the masonry chimney, consult a qualied mason or
chimney dealer. The installation must conform to local re codes,
and N.F.P.A. 211.
DO NOT CONNECT THIS FURNACE TO A CHIMNEY
FLUE SERVING ANOTHER APPLIANCE.
The chimney used for a furnace must not be used to ventilate the
cellar or basement. If there is a cleanout opening at the base of
the chimney, close it tightly.
LISTED FACTORY BUILT CHIMNEY
Carefully follow chimney manufacturer's instructions. Use only a
Listed Residential Type or Building Heating Appliance Chimney.
If your chimney starts at the ceiling (Fig. 7), you will need enough
6" pipe to reach the ceiling.
The top of the chimney must be at least 3 feet above the roof
and be at least 2 feet higher than any point of the roof within 10
feet (Fig. 7).
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 ex-
cessive draft.”
Take into account the chimney’s location to insure it is not too
close to neighbors or in a valley which may cause unhealthy or
nuisance conditions.

1. The crimped end of the chimney connector ts inside the furnace
ue collar. Install additional chimney connectors and elbow with
the CRIMPED END TOWARD THE FURNACE. This will allow any
condensation in the ue to run back into the furnace. Use 6" dia.
steel pipe and elbows for connection to chimney. Never use less
than 24 gauge and although blued steel is satisfactory, high temp
painted black is much more desirable. (See Figure 8)
2. Slope any horizontal pipe upward toward the chimney at least 1/4
inch for each foot of horizontal run.
3. You must have at least 18 inches of clearance between any hori-
zontal piping and the ceiling.(See Fig. 5)
4. The chimney connector must not extend into the chimney ue. (See
Fig. 9)
5. Seal each chimney connector pipe joint with furnace cement. Also
seal the pipe at the chimney.
6. Use 3 sheet metal screws at each chimney pipe joint to make the
piping rigid.
7. The chimney connector may include a section for a barometric
draft regulator between the furnace and the chimney (Fig. 6, 7, &
10). The barometric draft regulator must be installed in the same
room (same pressure zone) as the furnace.
8. Install the barometric draft regulator strictly in accordance with the
instructions that are provided with the barometric draft regulator.
9. A solid damper must be used in the chimney connecting pipes be-
tween the ue collar and the chimney. When used in conjunction
with a barometric draft regulator, the solid damper must be placed
between the barometric and the chimney. (See Fig. 6, 7, & 10)
ADJUSTING THE BAROMETRIC DRAFT
REGULATOR
1. Drill a hole in the chimney connector within 18" of the ue collar
below the barometric draft regulator just large enough for the tube
of the manometer.
2. Build a re after all chimney connections have been made.
3. Use a manometer to measure the draft in the ue.
4. Adjust the Barometric Draft Regulator to obtain a draft of 0.05 -
0.06" W.C. under stable re conditions.

CONNECTION OF CHIMNEY CONNECTOR TO A MASONRY CHIMNEY
THROUGH A COMBUSTIBLE WALL
Figure 8 shows how to connect the chimney connector of a heater to a masonry chimney through a combustible wall.
There are ve allowable ways that a chimney connector can be connected to a masonry chimney by passing through a combustible wall.
NFPA Standard 211 allows the following wall pass-through systems.
Figure 11
-11-
1. Use a minimum 3-1/2" thick brick masonry wall framed into the combustible wall. A reclay liner (ASTM C315 or
equivalent) having a 5/8" minimum wall thickness must be used and it must be at least 12" away from any material
that could catch re. The inside diameter of the reclay liner shall be sized for the proper snug t of a 6" diameter
chimney connector pipe. The reclay liner shall run from the outer surface of the brick wall to, but not beyond, the

be securely fastened to wall surfaces on all sides and shall
be sized to t and hold the chimney section. Fasteners used
to secure chimney sections shall not penetrate chimney ue
liner. See Part C.
4. Use an 8" inside diameter solid insulated listed factory-built
chimney length which has 1" or more of solid insulation. The
minimum length of this chimney section shall be 12" and
will serve as a pass-through for the 6" diameter chimney
connector. There must be at least a 12" air space between
the outer wall of the chimney section and any combustible
materials. The chimney section shall be concentric with
and spaced 1" away from the chimney connector by means
of sheet steel support plates on both ends of the chimney
section. The opening in the combustible wall shall be cov-
ered and the chimney section supported on both sides with
sheet steel supports which are at least 24 gauge (0.024")
in thickness. The sheet steel supports shall be securely
fastened to wall surfaces on all sides and shall be sized to
t and hold the chimney section. Fasteners used to secure
chimney sections shall not penetrate chimney ue liner. See
Part D.
5. A listed factory-built wall pass-through system may be pur-
chased and installed according to the instructions packaged
with it to provide a safe method of passing the chimney
connector through a combustible wall for connection to a
masonry chimney.
Additional requirements pertaining to Figure 8 and
the above wall pass-through systems:
1. Insulation material used as part of wall pass-through sys-
tem shall be of noncombustible material and shall have a
thermal conductivity of 1.0 Btu • in./ft.² • °F (4.88 kg cal/
hr • m² • °C) or less.
2. All clearances and thicknesses are minimums: larger clear-
ances and thickness are acceptable.
3. A chimney thimble, as shown for 3" and 4" above (Parts C
and D) shall be for types "3" and 4" connections to facili-
tate removal of the chimney connector for cleaning. The
chimney thimble shall be of ASTM C315 reclay with 5/8"
minimum wall thickness, or material or equivalent durabil-
ity. The inside diameter of the thimble shall be sized for
the proper snug t of a 6" diameter chimney connector
pipe. The thimble shall be installed without damage to the
chimney ue. The thimble shall extend through the chimney
wall to, but not beyond, the inner surface of the chimney
ue and shall be permanently cemented in place with high
temperature cement.
4. A chimney connector to a masonry chimney, except for 2"
above (Part B), shall extend through the wall pass-through
system to the inner face of the chimney ue, but not beyond.
It does not have to be fastened in place so long as it cannot
accidently be pulled out of the chimney or shoved into the
chimney ue. If fasteners are used to secure the chimney
connector to a masonry chimney, the fasteners shall not
penetrate the chimney ue liner.
5. Any material used to close up any opening for the connector
shall be noncombustible.
PART E - (Figure 12)
In addition to the methods shown by A, B, C, and D of
Figure 12, a listed factory-built wall pass-through system
may be purchased and installed according to the instruc-
tions packaged with it to provide a safe method of pass-
ing chimney connector through a combustible wall for a
connection to a masonry chimney.
If the chimney connector does not have to pass through a
combustible wall to get to a masonry chimney, simply con-
nect the chimney connector directly to the masonry chimney's
chimney thimble as described and shown by parts C and D of
Figure 12. Remember, the chimney connector should extend
into the chimney thimble to the inner face of the chimney ue
but not beyond; if the chimney connector is extended through
the chimney thimble into the chimney ue, resistance to the
ow of smoke and gases up the chimney will occur; that ow
resistance will have an adverse affect on the operation and
performance of the heater and venting system.

INSTALLATION
Please see all methods of Installation at the rear of this
booklet.
This is a furnace, not a free standing stove. You must direct
heated air from 8" outlets away from the furnace, or it will not
function properly.
1. This installation must be done by a qualied heating
equipment installer.
2. The installation is to be done in compliance with National
Fire Protection Association installation standards: No.
89M, 90B, 211, 70 (National Electrical Code) and Uniform
Mechanical Code 913, 6-4, in the states where applicable.
(Their code offers connecting smoke pipe connectors into
chimney with other fuel burning appliances.)
3. Rooms large in comparison with size of the appliance:
a) Coal Burning Furnace need air for combustion and
circulation to house.
b) Provision must be made to make up this air and not
starve gas or oil furnace of combustion air.
c) Have the "Authority Having Jurisdiction" determine that
air is of adequate makeup. (Reference N.F.P.A. Nos.
30&54, Code for Installation of Gas & Oil Equipment).
4. Have the "Authority Having Jurisdiction" to inspect all
chimneys and installations for adequate venting and for
compliance with standard and local codes and regulations
regarding installation of coal burning appliances.
5. Installation for Supplemental Heat Application to Existing
Central System.
a) Place Coal Burning Furnace so that the chimney
connector will be as short as practical and avoiding
unnecessary sharp turns in the smoke pipe connector
and the installation of devices that would create
excessive resistance to the ow of ue gases.
b) Locate the Coal Burning Furnace as close as practical to
the existing central hot air heating system, maintaining
clearances as stated on the label on the fuel door.
c) Clearance from combustible materials must comply with
those stated on the label on the side of the unit. Refer
to the clearance table in the front of this manual.
The installation must be made only on a noncombustible oor.
d) Install the smoke pipe connector to the chimney with
26-gauge pipe and elbows (to be purchased separately),
maintaining the proper clearances for the specic model.
Seal the smoke pipe in the chimney with furnace cement.
(The chimney connector shall be securely supported,
and joints fastened with sheet metal screws or rivets.)
e) Install 8" diameter heat pipe to plenum of the central
hot air furnace. Use 26-gauge pipe and connectors (to
be purchased separately). If central air conditioning is
installed in the plenum, install heat pipe above the air
conditioning unit. Secure heat pipe connection with
supports and sheet metal screws.
f) Connect electrical supply in the electrical junction box
that is mounted on the back of the Furnace. See Wiring
Diagram (Fig. 16). Remove the cover from electrical
junction box and connect power supply wires to wires
designated, using wire nuts. The power cord supplied
may be used for installation, if permitted by local codes
and regulations. If the power cord supplied cannot be
used, the power supply wiring must be 90 degrees
centigrade in a metal cable and should be completed
by a qualied installer complying with NFPA Standard
No. 70 and local codes.

The top down method of re building is recommended for
this appliance.
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. Saltwater driftwood or other previously saltwater saturated

TAMPER WARNING
This coal 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 coal heater in a
manner inconsistent with operating instructions in this manual.
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.
-16-
A draft reading of .05 to .06 w.c. is suggested for proper burning of this unit when using bituminous
coal as fuel. When using anthracite coal, this draft reading is a minimum reading.
CAUTION
Achimneyremaycauseignitionofwallstudsorrafterswhichyouthoughtwereasafedistancefrom
thechimney.Ifyouhaveachimneyre,haveyourchimneyinspectedbyaqualiedpersonbefore
using again.
EFFICIENCIES
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. The higher heating value is when water leaves
the combustion process completely condensed.
OVER FIRING
Attempts to achieve heat output rates that exceed heater design
specications can result in permanent damage to the heater.
ASH REMOVAL AND 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
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.
GASKETS
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.
This unit’s ash door uses a 5/8" diameter rope gasket. This
unit's feed door uses a 1/2" diameter rope gasket.
SERVICE HINTS
Do not expect a furnace to draw. It is the chimney that
creates the draft. Smoke spillage into the house or
excessive build-up of water or creosote in the chimney
are warnings that the chimney is not functioning properly.
Correct the problem before using furnace. Possible causes are:
1. The connector pipe may be pushed into the chimney too
far, stopping the draft.
2. Do not connect two furnaces or a stove and furnace into
the same chimney ue.
3. The chimney used for a furnace must not be used to
ventilate the cellar or basement. If there is a cleanout
opening at the base of the chimney, it must be closed tightly.
4. If the chimney is operating too cool, water will condense
in the chimney and run back into the furnace. Creosote
formation will be rapid and may block the chimney. Operate
the furnace at a high enough re to keep the chimney
warm, preventing this condensation.
5. If the re burns well, but sometimes smokes or burns
slowly, it may be caused by the chimney top being lower
than another part of the house or a nearby tree. The
wind blowing over a house or a tree, falls on top of the
chimney like water over a dam, beating down the smoke.
The top of the chimney should be at least 3 feet above
the roof and be at least 2 feet higher than any point of
the roof within 10 feet.
6. See page 18 for list of trouble shooting tips.
CHIMNEY MAINTENANCE
Creosote and Soot - Formation and Need for Removal
When coal is burned, the products of combustion combine with
moisture to form a soot residue which accumulates on the ue
lining. When ignited, this soot makes an extremely hot re.
The chimney should be inspected at least twice monthly
during the heating season to determine if a creosote or soot
build up has occurred.
If creosote or soot has accumulated, it should be removed to
reduce the risk of a chimney re.
Chimney res burn very hot. If the chimney catches re,
immediately call the re department, then reduce the re by
closing the inlet air control. Pour a large quantity of coarse
salt, baking soda or cool ashes on top of the re in the rebox.
ATTENTION:
This heater needs periodic inspection and repair for proper operation. It is against federal regulations
to operate this heater in a manner inconsistent with operating instructions in this manual.

TROUBLE SHOOTING TIPS FOR WARM AIR FURNACE
1. Problem:
Smoke puffs from furnace
Solution:
A. Check chimney draft. Check for blocked chimney or
ue pipe. Use mirror to check chimney clearance.
B. Check ash pit — if it is too full, empty.
C. Make sure furnace room is not too airtight.
D. Make sure all of chimney mortar connections are airtight.
E. Check ash drawer. Make sure it’s airtight.
F. Check chimney for possible down-draft caused by
taller surrounding trees or objects. Correct with proper
chimney vent cap.
G. Check the possibility of a cold chimney forcing cool
gases backward. Remedied by properly insulating
chimney with non-combustible liner non-combustible
insulation.
H. Fuel may be too green.
I. Make sure no other fuel burning devices are connected
to the chimney impairing the draft.
J. Check chimney draft, it should be .06 inches of water
column. This service is provided by a certied chimney
sweep.
2. Problem:
Inadequate heat being delivered to your home
Solution:
A. Check home insulation — is it adequate?
B. Check hook-up to furnace — is it installed correctly?
C. Cool air inlet may be inadequate or furnace room too
airtight.
D. Make sure your hot air duct (and other duct work) is
airtight.
E. If furnace room is warm but your home isn’t, check
back draft dampers.
F. Is air to the blower available?
3. Problem:
Excess smoke or ames coming out door when refueling
Solution:
A. Wait 15 seconds and open door SLOWLY then
refuel.
B. Check length of ue pipe to chimney. Your unit should
be within six (6) feet of your chimney.
C. Make sure chimney cap is not too close to the top of
the chimney.
D. Check chimney draft — make sure chimney ue pipe
is clean and chimney is of adequate height.
E. Slide bafe should be pulled out prior to load door
opening.
4. Problem:
Distribution blower vibrating
Solution:
A. Tighten blower wheel to motor shaft.
B. Check for bad fan bearings.
5. Problem:
