IMPORTANT SAFETY INFORMATION
37403-5-0620Page 4
SAFETY INFORMATION FOR USERS OF PROPANE GAS
Propane is a ammable gas which can cause res and explo-
sions. In its natural state, propane is odorless and colorless.
You may not know all the following safety precautions which
can protect both you and your family from an accident. Read
them carefully now, then review them point by point with the
members of your household. Someday when there may not
be a minute to lose, everyone's safety will depend on knowing
exactly what to do. If, after reading the following information,
you feel you still need more information, please contact your
gas supplier.
PROPANE GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas
because of the odorant put in the Propane Gas. That's your
signal to go into immediate action!
• Do not operate electric switches, light matches, use your phone.
Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• Propane Gas is heavier than air and may settle in low areas
such as basements. When you have reason to suspect a gas
leak, keep out of basements and other low areas. Stay out until
reghters declare them to be safe.
• Use your neighbor's phone and call a trained Propane Gas
service person and the re department. Even though you may
not continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and reghters check for escaped
gas. Have them air out the area before you return. Properly
trained Propane Gas service people should repair the leak,
then check and relight the gas appliance for you.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must nd out if you can
smell the odorant in propane. Smoking can decrease your ability to
smell. Being around an odor for a time can affect your sensitivity or
ability to detect that odor. Sometimes other odors in the area mask
the gas odor. People may not smell the gas odor or their minds are
on something else. Thinking about smelling a gas odor can make
it easier to smell.
The odorant in Propane Gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can lter the odorant. Odorants
in Propane Gas also are subject to oxidation. This fading can occur
if there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into
walls, masonry and other materials and fabrics in a room. That will
take some of the odorant out of the gas, reducing its odor intensity.
Propane Gas may stratify in a closed area, and the odor intensity
could vary at different levels. Since it is heavier than air, there may
be more odor at lower levels. Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immediately
go into action as instructed earlier.
SOME POINTS TO REMEMBER
• Learn to recognize the odor of Propane Gas. Your local Propane
Gas Dealer can give you a "Scratch and Sniff" pamphlet. Use
it to nd out what the propane odor smells like. If you suspect
that your Propane Gas has a weak or abnormal odor, call your
Propane Gas Dealer.
• If you are not qualied, do not light pilot lights, perform service,
or make adjustments to appliances on the Propane Gas system.
If you are qualied, consciously think about the odor of Propane
Gas prior to and while lighting pilot lights or performing service
or making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the Propane Gas odor. Do not try to
light pilot lights, perform service, or make adjustments in an
area where the conditions are such that you may not detect
the odor if there has been a leak of Propane Gas.
• Odor fade, due to oxidation by rust or adsorption on walls of
new cylinders and tanks, is possible. Therefore, people should
be particularly alert and careful when new tanks or cylinders
are placed in service. Odor fade can occur in new tanks, or
reinstalled old tanks, if they are lled and allowed to set too
long before relling. Cylinders and tanks which have been out
of service for a time may develop internal rust which will cause
odor fade. If such conditions are suspected to exist, a periodic
sniff test of the gas is advisable. If you have any question about
the gas odor, call your Propane Gas Dealer. A periodic sniff
test of the Propane Gas is a good safety measure under any
condition.
• If, at any time, you do not smell the Propane Gas odorant and
you think you should, assume you have a leak. Then take the
same immediate action recommended above for the occasion
when you do detect the odorized Propane Gas.
• If you experience a complete "gas out," (the container is under
no vapor pressure), turn the tank valve off immediately. If the
container valve is left on, the container may draw in some air
through openings such as pilot light orices. If this occurs, some
new internal rusting could occur. If the valve is left open, then
treat the container as a new tank. Always be sure your con-
tainer is under vapor pressure by turning it off at the container
before it goes completely empty or having it relled before it is
completely empty.

(formation of condensate, leakage, spillage, etc.) and shall
specify the following test procedure:
WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each
appliance connected to the venting system being
placed into operation could result in carbon monoxide
poisoning or death.
The following steps shall be followed for each
appliance connected to the venting system being
placed into operation, while all other appliances
connected to the venting system are not in operation:
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and
horizontal pitch, as required in the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 or the Natural
Gas and Propane Installation Code, CSA B149.1
and these instructions. Determine that there is no
blockage or restriction, leakage, corrosion and
other deciencies which could cause an unsafe
condition.
3. As far as practical, close all building doors and
windows and all doors between the space in which
the appliance(s) connected to the venting system
are located and other spaces of the building.
4. Close replace dampers.
5. Turn on clothes dryers and any appliance not
connected to the venting system. Turn on any
exhaust fans, such as range hoods and bathroom
exhausts, so they are operating at maximum
speed. Do operate a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance
being inspected into operation. Adjust the
thermostat so appliance is operating continuously.
7. Test for spillage from draft hood equipped
appliances at the draft hood relief opening after 5
minutes of main burner operation. Use the ame
of a match or candle.
8. If improper venting is observed during any of the
above tests, the venting system must be corrected
in accordance with National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and/or Natural Gas and Propane
Installation Code, CSA B149.1.
9. After is has been determined that each appliance
connected
to the venting system properly vents
when tested as outlined above, return doors,
windows, exhaust fans, replace dampers and
any other gas-red burning appliance to their
previous conditions of use.

GAS SUPPLY
Installing a New Main Gas Shut-Off
Each appliance should have its own manual gas shut-off.
A manual main gas shut-off should be located in the vicinity of the
unit. Where none exists, or where its size or location is not adequate,
contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liqueed petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed ame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required by
the National Fuel Gas Code that a drip line be installed near the gas
inlet. This should consist of a vertical length of pipe tee connected
into the gas line that is capped on the bottom in which condensation
and foreign particles may collect.
Figure 2
Method of Installing a Tee Fitting Sediment Trap
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.
plugged tapping, accessible for test gauge connection, must be
placed immediately upstream of the gas supply connection to
the appliance.
2. The appliance and its individual shut-off valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1/2 psig (3.5 kPa).
3. The appliance must be isolated from the gas supply piping system
by closing its individual manual shut-off valve during any pressure
testing of the gas supply piping system at test pressures equal
to or less than 1/2 psig (3.5 kPa).
37403-5-0620 Page 9
Clearances
1. In selecting a location for installation, it is necessary to provide
adequate accessibility clearances for servicing and proper
installation.
2. The DVC-55 minimum wall depth is 4-1/2 inches and maximum
wall depth is 13 inches. The use of tubes not supplied by the
manufacturer results in unsatisfactory performance.
3. The DVC-55 can be attached to the wall or recessed into the
wall up to 4 inches in depth but the minimum 4-1/2 inches vent/
air intake system wall depth must be maintained.
Example: If furnace is recessed into the wall at a depth of
4 inches, the minimum wall depth must be 8-1/2 inches.
4. The wall in which the furnace is recessed has (0) zero clearance
to the furnace sides and top.
5. When using side discharge registers, SOR-1 or SOK-1, the
furnace cannot be recessed into the wall.
6. Clearance to sidewall or combustible material is 4 inches.
7. Ceiling clearance is 4 inches.
8. Floor and rear wall clearance is (0) zero inches.
9. Clearance of 18 inches is required to sidewall or combustible
material when ush mounted SOR-1, side outlet register is
used.
10. The minimum distance from the center of the vent cap to the
nearest outside corner or obstruction is 24 inches.
The vent terminal of a direct vent appliance with an input over 50,000
BTU per hour shall be located at least 12 inches from any opening
through which ue gases could enter a building. The bottom of the
vent terminal and the air intake shall be located at least 12 inches
above grade.
WARNING: The nearest point of the vent cap should be a
minimum horizontal distant of six (6) feet from any pres-
sure regulator. In case of regulator malfunction, the six
(6) feet distance will reduce the chance of gas entering the
vent cap.
Figure 4
CLEARANCES
Attention! If one of the above procedures results in pressures in
excess of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve,
it will result in a hazardous condition.
Figure 3
Checking Manifold Pressure
Both Propane and Natural Gas valves have a built-in pressure
regulator in the gas valve. Natural Gas models will have a manifold
pressure of approximately 3.5" w.c. at the valve outlet with the inlet
pressure to the valve from a minimum of 5.0" w.c. for the purpose of
input adjustment to a maximum of 7.0" w.c. Propane Gas models
will have a manifold pressure approximately 10.0" w.c. at the valve
outlet with the inlet pressure to the valve from a minimum of 11.0"
w.c. for the purpose of input adjustment to a maximum of 13.0" w.c.
A 1/8" N.P.T. plugged tapping, accessible for test gauge connection,
is located on the outlet side of the gas control.
The built-in regulator comes on at approximately 1/4th pressure
and full on in 10 seconds.
Safety Lockout
S8600H module provides 100 percent shutoff, or safety
lockout. If the pilot fails to light within 90 seconds, the
control system will shut down. The control system must be
reset by turning off power to the module for one minute.

bustion chamber and collar of vent cap. Remove old furnace
cement from both ends of 4" diameter ue outlet tube.
3. Attach 6" diameter air inlet tube onto the collar of air drop
assembly. Attach caulked, outside mounting plate into the 6"
diameter air inlet tube. Position the outside mounting plate
so that 6" diameter air inlet tube has a slight downward slope
to the outside. The downward slope is necessary to pre-
vent the entry of rainwater. Attach outside mounting plate
to exterior wall with (4) #10 x 1" screws provided.
4. Apply furnace cement to 4" diameter ue outlet collar on
combustion chamber and to 4" diameter collar on vent cap.
Attach 4" diameter ue outlet tube onto ue outlet collar on
combustion chamber. Attach vent cap into the 4" diameter
ue outlet tube. Attach vent cap to outside mounting plate
with (3) #10 x 1/2" screws provided.
5. Reassembly and resealing vent-air intake system is com-
pleted.
Installing a Vent Near a Window Ledge,
Other Type of Projection or on Siding (vinyl, aluminum, etc.)
Direct vent furnaces are designed to be installed on a uniform
outside wall. When the wind comes from any angle (up, down or
from either side), it must hit the vent cap equally over both the air
inlet and the ue outlet portions of the vent. Any wall projection,
such as a door or window casing, which disturbs the wind on one
side of the air inlet section will result in back pressure on the ue
section smothering the ame and eventual pilot outage.
When the vent cap is to be installed on siding or it appears that a
projection within 6" of any side of the air inlet section could shield
the air inlet section, the entire vent should be supported away
from the wall at least the distance of the projection. 2" x 4" fram-
ing whose outside dimensions match the overall dimensions of
the mounting plate is recommended. The 2" x 4" framing protects
siding from possible warpage or discoloration. All joints can then
be sealed and painted. The wall depth plus the additional depth
of the 2" x 4" framing should not exceed a total depth of 13" for
DVC-55. See Figure 9.
Vinyl siding vent kit, DV-822, is available from Empire Comfort
Systems, Inc. The depth is 3", which enables the vent cap to be
extended away from siding or projections. The wall depth plus the
additional 3" depth of the vinyl siding vent cap extension should
not exceed a total depth of 13" for DVC-55. See Figure 10.
Warning: When vinyl siding vent kit, DV-822 or 2" x 4"
framing is added to an existing installation (furnace is
installed) do not attempt to add sections of pipe to the ue
outlet tube or air inlet tube. An air tight seal is required for
both tubes. Refer to Parts List, page 21 to order tubes.

37403-5-0620Page 14
Figure 11
Electrode and pilot burner must be kept clean. Clean through
pilot access hole with a small brush (toothbrush) and water.
The pilot ame (Figure 11) going to the spark must be large enough
to completely cover the sparking area. With the proper ame, only
2 or 3 sparks will occur. More sparks indicate a small pilot ame
and no ignition with spark stopping after approximately 90 seconds
generally means not enough ame.
To adjust pilot ame remove the pilot cover screw on the control
valve (Figure 3, Page 9), and turn the adjustment screw clockwise
to reduce ame. Replace pilot cover screw to eliminate gas leakage.
The pilot ame will appear large. A blue nearly horizontal ame is
proper. The spark gap must be 1/8". A larger gap can result in the
spark occurring some other place. The pilot ame and the spark
gap are factory checked and tested.
After use, cleaning may be required for the proper ame.
The correct ame will be a short blue inner ame with a much
larger light blue outer ame. The main burner (Figure 12) shows
the approximate height of each part of the ame for each gas. The
burner does not have a primary air adjustment. The ame will be
correct if the factory-set pressure and orice opening are used. After
the furnace has been operating, the burner ports may be blocked
by foreign matter carried in by combustion air. Therefore, cleaning
of the burner may be needed for proper ame.
To clean burner port disconnect the gas supply to the valve, and
remove the eight screws fastening the burner door. After removing the
burner door from the combustion chamber, remove rear burner, pilot
burner and front burner. With front and rear burners removed from
furnace, force water into the ribbon ports and dry with air pressure.

Wiring
The appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the
National Electrical Code, ANSI/NFPA 70 or Canadian Electrical Code, CSA C22.1, if an external electrical source is utilized. This appliance
is equipped with a three-prong [grounding] plug for your protection against shock hazard and should be plugged directly into
a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug. For an ungrounded
receptacle, an adapter, which has two prongs and a wire for grounding, can be purchased, plugged into the ungrounded receptacle and
its wire connected to the receptacle mounting screw. With this wire completing the ground, the appliance cord plug can be plugged into
the adapter and be electrically grounded. A 7/8" hole is provided in the junction box for use with a conduit connector if local codes require
this type of protection.
Installing the ON/OFF Device
To install an ON/OFF device (such as a wall switch, remote, toggle switch,or thermostat), remove the wire nut from the two wires from
the valve. Run additional wire from the valve wires to the ON/OFF device. Install the ON/OFF device in the same room as the furnace
following the installation instructions supplied with it. In the absence of instructions, install the ON/OFF device 4 to 5 feet above the oor
on an interior wall not affected by another heating source (i.e. stove or water heater) or the temperature of an adjoining room.
CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.
Verify proper operation after servicing.
To Conserve Gas: Turn off pilot when heater is not in use.

37403-5-0620Page 16
GENERAL: All furnaces have been re-tested to check for proper
operation. This includes, main burner ame, pilot ame, fan
operation, fan control, limit control and automatic valve operation.
If the furnace fails to function on initial installation, it is advisable to
re-check the following:
1. 115 volts to the junction box.
2. Inlet gas pressure.
3. The 24 volt system.
4. Type of gas being used and that shown on the rating label.
Servicing the Pilot and Main Burners, Pilot Orice, and Main
Burner Orices: Disconnect the gas supply at the inlet to the
control valve. Then remove the burner door to which the above
components are attached.
Servicing The Fan Motor: The upper front panel, the shroud
surrounding the fan blade and fan blade must be removed.
Replacing Fan and Oiling the Motor
The fan motor should be cleaned and oiled once each heating season.
To reach the motor, withdraw the metal shroud surrounding the fan
blade by removing the screws on each side. Oil holes are located
on the top at each end of the motor. Use a few drops of #10 motor
oil. To clean the motor, blow air through its ventilation openings
with a vacuum cleaner or low pressure air source.
If fan motor is replaced, the silicone rubber gaskets, see Page 20,
Index No. 4, Part No. M147, should also be replaced. The gaskets
must be stretched to t the motor bolts into the gasket holes and
then the motor and gaskets installed on the motor mounting bars.

Specications.
STEP 3: Reset the Module.
A. Turn the control valve to off.
B. Wait one minute.
As you do Steps 4 and 5, watch for points where operation
deviates from normal. Refer to Troubleshooting Chart to correct
problem.
STEP 4: Check Safety Lockout Operation.
A. Turn gas supply off.
B. Watch for spark at pilot burner.
C. Time length of spark operation. Maximum spark time is 90
seconds.
D. Open manual gas cock and make sure no gas is owing to pilot
or main burner.
E. Wait one minute before continuing.
STEP 5: Check Normal Operation.
A. Turn contol valve on to call for heat.
B. Make sure pilot lights smoothly when gas reaches the pilot
burner.
C. Make sure main burner lights smoothly without ashback. Make
sure burner operates smoothly without oating or lifting.
D. If gas line has been disturbed, complete gas leak test.
GAS LEAK TEST: Paint gas control gasket edges and all pipe
connections downstream of gas control, including pilot tubing
connections, with rich soap and water solution. Bubbles indicate
gas leaks. Tighten joints and screws or replace component to
stop gas leak.
E. Turn control valve off. Make sure main burner and pilot ames
go out.
OPERATION
Module operation can be conveniently divided into two phases for
S8600H. The phases are trial for ignition and main burner operation.
SERVICE & MAINTENANCE SUGGESTIONS
37403-5-0620 Page 17
TRIAL FOR IGNITION
Pilot Ignition
Following call for heat (system start on S8600H), the module
energizes the rst main valve operator. The rst main valve opens,
which allows gas to ow to the pilot burner. At the same time, the
electronic spark generator in the module produces a 13,000 volt
spark pulse output (at 25 pf load). The voltage generates a spark
at the igniter-sensor that lights the pilot.
If the pilot does not light, or the pilot ame current is not at least 1.0
uA and steady, the module will not energize the second main valve
and the main burner will not light.
Safety Lockout
S8600H provides 100 percent shutoff, or safety lockout. A timer
starts timing the moment the trial for ignition starts. Ignition spark
continues only until the timed trial for ignition period ends. Then
the module goes into safety lockout. Lockout de-energizes the
rst main valve operator and closes the rst main valve in the gas
control, stopping pilot gas ow. The control system must be reset
by turning the valve off for one minute or by turning off power to the
module for one minute.
Main Burner Operation
When the pilot ame is established, a ame rectication circuit
is completed between the sensor and burner ground. The ame
sensing circuit in the module detects the ame current, shuts off
the spark generator and energizes the second main valve operator.
The second main valve opens and gas ows to the main burner,
where it is ignited by the pilot burner. The ame current also holds
the safety lockout timer in the reset (normal) operating condition.
When the call for heat ends, both main valve operators are de-
energized, and both main valves in the gas control close.

Important
1. The following service procedures are provided as a general
guide.
2. Meter readings between gas control and ignition module must
be taken within the trial for ignition period. Once the ignition
module locks out, the system must be reset by turning the valve
off for at least one minute before continuing.
3. If any component does not function properly, make sure it is
correctly installed and wired before replacing it.
4. The ignition module cannot be repaired. If it malfunctions, it
must be replaced.
5. Only trained, experienced service technicians should service
intermittent pilot systems.
Perform the CHECKOUT steps on page 15 as the rst step in
troubleshooting. Then check TROUBLESHOOTING GUIDE to
pinpoint the cause of the problem. If troubleshooting indicates an
ignition problem, see Ignition System Checks below to isolate and
correct the problem.
Following troubleshooting, perform the CHECKOUT procedure
(page 15) again to be sure system is operating normally.
Ignition System Checks
Step 1: Check ignition cable.
Make sure:
A. Ignition cable does not touch any metal surfaces.
B. Ignition cable is no more than 36 inches long.
C. Connections to the ignition module and to the igniter-sensor
are clean and tight.
D. Ignition cable provides good electrical continuity.
Step 2: Check ignition system grounding.
Nuisance shutdowns are often caused by a poor or erratic
ground.
A. A common ground, usually supplied by the pilot burner bracket,
is required for the module and the pilot burner/igniter sensor.
• Check for good metal-to-metal contact between the pilot
burner bracket and the main burner.
• Check the ground lead from GND (BURNER) terminal on the
module to the pilot burner. Make sure connections are clean
and tight. If the wire is damaged or deteriorated, replace it
with No. 14-18 gauge, moisture-resistant, thermoplastic
insulated wire with 105 C (221 F) minimum rating.
• If ame rod or bracket are bent out of position, restore to
correct position.
• Replace pilot burner/igniter sensor if insulator is cracked.
Step 3: Check spark ignition circuit. You will need a short jumper
wire made from ignition cable or other heavily insulated
wire.
A. Close the manual gas valve.
B. Disconnect the ignition cable at the SPARK terminal on the
module.
WARNING
When performing the following steps, do not touch stripped end of
jumper or SPARK terminal. The ignition circuit generates 13,000
volts at 25 pf load and electrical shock can result.
C. Energize the module and immediately touch one end of the
jumper rmly to the GND terminal on the module. Move the
free end of the jumper slowly toward the SPARK terminal until
a spark is established.
D. Pull the jumper slowly away from the terminal and note the
length of the gap when sparking stops. Check table below.
ARC LENGTH ACTION
No arc or arc less than
1/8 inch
Arc 1/8 inch or longer
Check external fuse, if provided.
Verify power at module input terminal.
Replace module if fuse and power
okay.
Voltage output is okay.
Step 4: Check pilot ame current.
A. Turn off furnace.
B. Disconnect main valve wire from the TH or MV terminal on the
gas control.
C. Disconnect ground wire from GND (BURNER) terminal at
module.
D. Connect a meter (dc microamp scale) in series with the ground
lead.
• Disconnect ground lead from GND terminal on ignition module.
• Connect the black (negative) meter lead to the ignition module
GND (BURNER) terminal.
• Connect the red (positive) meter lead to the free end of the
ground lead.
E. Turn valve on to call for heat. The spark will light the pilot but
the main burner will not light because the main valve actuator
is disconnected.
F. Read the meter. The ame sensor current must be steady and
at least 1.0 uA.
G. If the reading is less than the minimum or unsteady,
• Make sure pilot ame envelopes 3/8 to 1/2 inch of the ame
rod.
• If necessary, adjust pilot ame by turning the pilot adjustment
screw on the gas control clockwise to decrease or counter-
clockwise to increase pilot ame. Following adjustment,
always replace pilot adjustment cover screw and tighten
rmly to assure proper gas control operation.
• Check for cracked ceramic insulator, which can cause short
to ground, and replace igniter-sensor if necessary.
• Make sure electrical connections are clean and tight. Replace
damaged wire with moisture-resistant No. 18 wire rated for
continuous duty up to 105 C (221 F).
H. Remove meter and reconnect all wires. Return system to normal
operation before leaving job.
