THIS IS A HEATING APPLIANCE
DO NOT OPERATE THIS APPLIANCE WITHOUT FRONT PANELS INSTALLED.

Some people cannot smell well. Some people cannot smell
the odor of the chemical stench put into the gas. You must
findoutifyoucansmelltheodorantinpropane. Smokingcan
decrease your ability to smell. Being around an odor for a time
can affect your sensitivity or ability to detect that odor. Some-
times other odors in the area mask the gas odor. People may not
smell the gas odor or their minds are on something else. Think-
ing about smelling a gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under
some circumstances. For example, if there is an underground
leak,themovementofthegasthroughsoilcanfiltertheodorant.
Odorants in LP-Gas also are subject to oxidation. This fading

whentheremaynotbeaminutetolose,everyone'ssafetywill
depend on knowing exactly what to do. If, after reading the
followinginformation,youfeelyoustill need more informa-
tion, please contact your gas supplier.
Propane (LP-Gas) is a flammable gas which can cause fires
and explosions. In its natural state, propane is odorless and
colorless. Youmaynotknowallthefollowingsafetyprecau-
tions which can protect both you and your family from an
accident. Read them carefully now, then review them point
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.
LP-Gasmaystratifyinaclosedarea,andtheodorintensitycould
varyatdifferentlevels. Sinceitis 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.
•LearntorecognizetheodorofLP-gas. YourlocalLP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it
to find out what the propane odor smells like. If you suspect
thatyour LP-Gashasa weakorabnormal odor,call yourLP-
Gas Dealer.
• If you are not qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. Ifyouarequalified,consciouslythinkabouttheodor
ofLP-Gaspriorto and while lightingpilotlightsor perform-
ing service or making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-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 LP-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 filled and allowed
to set too long before refilling. Cylinders and tanks which
have been out of service for a time may develop internal rust
whichwillcauseodorfade. Ifsuch 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 LP-gas
dealer. AperiodicsnifftestoftheLP-gasisagoodsafety
measure under any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the
sameimmediateactionrecommendedabovefortheoccasion
when you do detect the odorized LP-Gas.
• If you experience a complete "gas out," (the container is
under no vapor pressure), turn the tank valve off immedi-
ately. Ifthecontainervalveislefton,thecontainermaydraw
in some air through openings such as pilot light orifices. 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 container is under vapor pressure by
turningitoffatthecontainerbeforeitgoescompletelyempty
or having it refilled before it is completely empty.
SAFETY INFORMATION FOR USERS OF LP-GAS
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Geteveryoneoutofthebuilding,vehicle,trailer,orarea. Do
that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-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
firefighters declare them to be safe.
• Useyourneighbor'sphoneandcallatrainedLP-Gasservice
person and the fire 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 firefighters check for
escaped gas. Have them air out the area before you return.
Properly trained LP-Gas service people should repair the
leak, then check and relight the gas appliance for you.
SOME POINTS TO REMEMBER
NO ODOR DETECTED - ODOR FADE
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!

Gas Supply
Check all local codes for requirements, especially for the size and type
of gas supply line required. On Natural gas lines less than 15' (4.5m)
long, use 1/2" (13mm) pipe; on longer runs, use 3/4" (19mm) iron pipe
or equal. On LP gas lines please consult LP gas supplier.
Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock 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.

Never use an exposed flame 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.

Than All-Metal Construction
Theaboveconnectors may beusedifacceptableby theauthorityhaving
jurisdiction.
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. Theappliance anditsindividual shutoffvalvemust bedisconnected
fromthegassupplypipingsystemduringanypressuretestingofthat
system at test pressures in excess of 1/2 psig (3.5 kPa).
3. Theappliancemustbeisolatedfromthegassupplypipingsystemby
closing its individual manual shutoff 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).
Attention! Ifone ofthe aboveprocedures resultsin pressuresin excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve, it will result
in a hazardous condition.
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 4.0" w.c. (.996kPa) at the valve outlet with the inlet
pressure to the valve from a minimum of 5.0" w.c. (1.24kPa) for the
purpose of input adjustment to a maximum of 10.5" w.c. (2.615kPa).
Propane gas models will have a manifold pressure approximately 10.0"
w.c.(2.49kPa)atthevalveoutletwiththeinletpressuretothevalvefrom
aminimumof11.0"w.c.(2.739kPa) forthepurposeofinputadjustment
to a maximum of 13.0" w.c. (3.237kPa).
A 1/8" (3mm) N.P.T. plugged tapping, accessible for test gauge
connection, is located on the outlet side of the gas control.

To light the pilot, it is important that the electrode be 1/8" (3mm) from
the thermocouple. The spark must occur at the point the burner flame
hits the thermocouple. The end of the electrode will be red hot with the
pilot on.
On a new installation with air in the gas line, it is suggested that a match
be used. The match will light the pilot faster than the piezo under this
condition.
Proper Pilot Flame
The correct pilot flame (Figure 6) will be blue, extending past the
thermocouple. Theflamewillsurroundthethermocouplejustbelowthe
tip.
Natural gas pilots require adjusting when the inlet gas pressure is above
5" w.c. (1.245kPa). Remove the pilot cover screw on the control valve
(Figure 5), and turn the adjustment screw clockwise to reduce flame.
Replace pilot cover screw to eliminate gas leakage.
LP gas (propane) will not require adjustment.
After use, cleaning may be required for the proper flame.
PROPER FLAME ADJUSTMENT
Figure 6
Proper Main Burner Flame
The correct flame will be a short blue inner flame with a much larger
lightblueouterflame. Themainburner(Figure7)showstheapproximate
height of each part of the flame for each gas. The burner does not have
a primary air adjustment. The flame will be correct if the factory-set
pressure and orifice opening are used. After the furnace has been
operating, the burner ports may be blocked by foreign matter carried in
bycombustion air. Therefore,cleaning of theburner maybe needed for
proper flame.
To clean burner port disconnect the gas supply to the valve, and remove
the eight screws fastening the burner door. After removing the burner
doorfromthecombustionchamber,removerearburner,pilotburnerand
front burner. With front and rear burners removed from furnace, force
water into the ribbon ports and dry with air pressure.

with a conduit connector if local codes require this type of protection.
Thermostat Installation
The thermostat should be installed in the same room as the furnace 4'
(1.2m) to 5' (1.5m) above the floor and away from another heat source
(cooking stove, hot water heater, etc.) including walls and doorways
with a heat source in an adjoining room. Do Not Install Thermostat
on Outside Wall.
Insulated Vent Enclosure

the wall furnace to shut "OFF" by the vent safety switch. To prevent
delayed venting as well as condensation of flue products an insulated
vent enclosure is recommended.
Use type B vent pipe and maintain at least a one inch (25mm) clearance
to combustibles.

Vent Safety Shutoff System
This appliance must be properly connected to a venting system. This
appliance is equipped with a vent safety shutoff system.
Warning: Operation of this wall furnace when not connected
to a properly installed and maintained venting system or
tampering with the vent safety shutoff system can result in
carbon monoxide (CO) poisoning and possible death.
This furnace is equipped with a manual reset vent safety switch. The
manual reset vent safety switch will cause gas flow to the main burners
to "shut off" due to improper venting or a blocked flue.
To reset the manual reset vent safety switch:
1. Remove upper front panel.
2. Depress red manual reset button. The manual reset vent safety
switch is located on the draft diverter.
3. Replace upper front panel.
Ifthemanualresetventsafetyswitchcontinuesto"shutoff"thegasflow
to the main burners a qualified service person must be contacted to
inspect for improper venting, blockage in the vent pipe or the manual
reset vent safety switch for being defective.

SERVICE AND MAINTENANCE SUGGESTIONS
CALL SERVICEMAN
GENERAL : All furnaces have been fire-tested to check for proper
operation. Thisincludes,main burner flame,pilotflame,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.
The Service Department at Empire Comfort Systems, Inc. may be
contacted to assist in servicing furnace.
ServicingthePilotandMainBurners,PilotOrifice,Thermocouple,
and Main Burner Orifices: Disconnect the gas supply at the inlet to
the control valve. Then remove the burner door to which the above
components are attached.
ServicingTheFanMotor: Theupperfrontpanel,theshroudsurround-
ingthefanbladeandfanblademustberemoved. See"OilingtheMotor"
paragraph on page 7.
Spark Igniter Does Not Light Pilot: With air in the gas line, such as
when the furnace is first installed or was off all summer, the pilot flame
may be too lean to ignite on the first few trials. Turn the control valve
knob to pilot position and depress the red reset button. Holding the
button down continually to bleed the line;.
1. Use lighter rod to light pilot with a match.
2. Use the piezo ignitor at 30 second intervals until it lights.
If Electrode Does Not Produce Spark:
1. Check wire connections.
2. Check gap for pilot burner to the electrode tip. Should be between
1/8" (3mm)and3/16"(5mm). Electrodewireandtipmustbemore
than 1/4" (6mm) away from all other metal components.
If Pilot Does Not Light By Any Means:
1. Check valve knob for being in the "Pilot" position.
2. Check pilot adjustment for being full open (counterclockwise to
open).
3. Ifgas isavailablein thesupplytubing, thepilotorifice and/orpilot
burnerisprobablyrestrictedbyaspiderweb. Cleanpilotassembly
and relight.
If Pilot Does Not Remain On After Releasing Knob:
1. Follow instructions and hold button down longer and harder.
2. Determine if pilot flame extends past thermocouple; if not, adjust
input or clean pilot burner.
3. Replace thermocouple if millivolts read less than 15 millivolts.
Main Gas Valve Does Not Open When Thermostat Is Turned To On:
1. Check for 24 volts to valve by removing one wire and touching to
the SAME TERMINAL it was on. Terminal should have a light
spark. DO NOT SHORT ACROSS TERMINALS, AS IT
WILL BURN OUT THE WALL THERMOSTAT.
2. Thermostat wires at the wall may be shorted, so check for a faulty
thermostat.
3. To check for line voltage to furnace, remove lower front panel and
switch compartment cover and short across two-terminal fan
control to allow fan to operate (Figure 9).
CAUTION: Label all wires prior to disconnection when servicing
controls. Wiringerrorscancauseimproperanddangerousoperation.
Verify proper operation after servicing.
