SAFETY INFORMATION FOR USERS OF LP-GAS
Propane (LP-Gas) is a ammable gas which can cause res
and explosions. 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.
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!
• 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.
• 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 reghters
declare them to be safe.
• Use your neighbor’s phone and call a trained LP-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 reghters 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.
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 LP-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
LP-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.
LP-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 LP-gas. Your local LP-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 LP-Gas has a weak or abnormal odor, call your LP-Gas
Dealer.
• If you are not qualied, do not light pilot lights, perform service,
or make adjustments to appliances on the LP-Gas system. If
you are qualied, consciously think about the odor of LP-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 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 lled and allowed to set too
long before relling. 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 LP-gas dealer. A periodic
sniff test of the LP-gas is a good safety 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 same
immediate action recommended above for the occasion 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 immediately. If the
container valve is left on, the container may draw in some air
through openings such as pilot light orices. 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 relled before it is
completely empty.

ual Mode. If operating in Local mode, the heat level will adjust
automatically.
4. The red and green control panel LED lights will begin to ash
alternately while the wall furnace performs a safety test. After
approximately 45 seconds the test will complete and the wall
furnace will prepare to ignite.
5. After the safety test is complete, the ignitor will glow red and
the burner will light within approximately 30 seconds.
Notice: If the burner fails to light, the wall furnace will retry the
ignition sequence three times then enter lock-out mode if it fails
to light. See page 39 for the fault codes and their meanings.
6. After the burner lights, the ame icon on the display panel will
appear and the wall furnace will automatically adjust to the
heat level shown on the display. The wall furnace will always
ignite on Level 5 (High) prior to adjusting to the heat level
shown on the display panel. See Figure 14.

tion, the wall furance will automatically reactivate in “Remote” (--)
mode and all operation settings will have reset to the factory de-
faults. If the wall furnace is normally operated using Manual mode
or with the built-in thermostat, the operation settings will need to
be manually reset to the desired mode and settings to resume
operation.
Installing an optional Millivolt thermostat allows the wall furnace to
automatically resume operation once power is restored.
Circulating Air Blower Operation
The circulating air blower is operated by a built in timer. The blower
will activate after approximately 45 to 70 seconds depending on
heat level. The blower will automatically adjust its speed to match
the heat level. The blower icon and speed are indicated on the
display panel. See Figures 16 to 19.

Figure 17 - Heat Level 3, Blower Speed 2
Figure 18 - Heat Level 4, Blower Speed 3
Figure 19 - Heat Level 5, Blower Speed 4
After the wall furnace is turned off, the blower will continue to oper-
ate for 100 to 160 seconds to ensure the wall furnace cools suf-
ciently.
Notice: When the wall furnace is turned off, the blower speed will
be displayed while it is running.

Humidier Operation
With the optional humidication tray kit (page 15), as the wall fur-
nace operates condensate is collected and transferred to a pan in
the bottom of the wall furnace. When the condensate reaches a
certain level, a heating element evaporates the water into the air
stream.
While the condensate is being evaporated, the “AUX” symbol will
be displayed. See Figure 20.
Notice: The humidier may not operate with every cycle.

Where will the wall furnace be installed?
• On the Floor - Wall Furnace comes equipped from
factory for this option. See Page 21.
• Wall Mounted - Wall mount shroud needed. See
Page 15 for kit number.
• Mount wall furnace at a height so that the con-
trols can still be observed.
• Interior Wall - Maximum vent length is 50 feet.
• Exterior Wall
• Locate Electrical Supply - Extension cords may
NOT be used.
• Wall Furnace Dimensions page 16.
• Clearances to Combustibles page 17.
What kind of venting application will be used?
• Single Flue - Wall Furnace comes equipped from
factory for this option. A 2” or 1-1/2” pipe may be
used. If a 1-1/2” pipe is used, it must be enlarged to
a 2” pipe prior to exiting the wall into the shroud.
• Direct Vent - An “Air Pipe Kit” is required and is
available for order. See page 15.
How will the venting be run?
• Straight out the back - Wall Furnace comes
equipped from factory for this option. Standard Rear
Shroud supplied. See page 27.
• In Front of the wall - Deep Shroud needed. Venting
option may NOT be done in Wall Mount installations.
See page 15 for kit number.
• Venting Guidelines pages 25 to 32.
• Maximum vent length is 50 feet.
• Notice: Clean all debris from the inside of the ue
pipe prior to applying the glue and nal assembly
of the pipe. Since the condensate is designed to
ow back to the appliance this debris will be carried
to the condensate trap resulting in a clog. An “A2”
error will appear on the display panel if this happens.
The clog, and the work required to x it, can be eas-
ily prevented by pulling a wet cloth through the pipe
prior to applying the glue and nal assembly.
How will the condensate be disposed?
• To a drain - Wall Furnace comes equipped from the
factory to drain up to 3 feet away from the appliance.
• An Extension Kit and External Condensate Pump
kit may also be used. See page 15 for kit numbers.
• Humidication - Optional Heated Humidication Tray
Kit available for order. See page 15 for kit number.
• Winterization information on page 41.
How will the wall furnace be operated?
• Remote - external Millivolt thermostat, wall switch or
remote control. See page 15 for kits available from
Empire Comfort Systems.
• Manual - use the display panel to control the heating
level and turn the wall furnace on and off.
• Local (Internal Thermostatic) - Factory installed
temperature probe on the wall furnace with a built-
in thermostatic function to control the wall furnace’s
operation.
• If it is desired to use the temperature sensed in
another part of the room, a wired temperature
probe accessory kit is available. See page 15 for
kit numbers.
• See Operation Instructions pages 7 to 12.
• Notice: Following a power outage, this wall furnace
will not automatically resume operation when oper-
ated manually or with the internal thermostat. Once
power is restored, the wall furnace will automatically
power on in “Remote Mode” (--), and the original op-
eration settings will need to be re-entered. Installing
an optional Millivolt thermostat control allows the wall
furnace to automatically resume operation under that
thermostat’s control once power is restored. Ask your
dealer for details.
