PIEZO LIGHTING INSTRUCTIONS
This unit is equipped with a Piezo (spark) for lighting the pilot
without removing the lighter hole cover. A lighter rod is supplied
and can be used to see if the pilot is getting gas and also for faster
lighting when there is excessive air in the lines.
REGISTER TEMPERATURE CONTROLS
The register temperature control has two positions. LOW HEAT
(Black) output and FULL HEAT (Red) output. Use the low posi-
tion when children are present. This will cause your furnace to
turn off and on several times before the living area is completely
comfortable. This is normal and limits the register temperature
to a maximum of 235°F.
CAUTION
Contact of bare skin on the hot air register may result in burns
when the appliance is in operation. KEEP CHILDREN OFF!
You can reduce the heat of the register by moving the register
temperature control.
MILLIVOLT INFORMATION
500 average with the thermostat OFF.
225 average with the thermostat ON.
140 minimum for valve to open.
65 minimum for pilot to stay on.
CAUTION: Label all wires prior to disconnection when
servicing controls. Wiring errors can cause improper and
dangerous operation. Verify operation after servicing.
TROUBLESHOOTING INFORMATION
A. All units have been fire-tested to check the operation of the
furnace. This includes the BTU input, main burner flame, pilot
flame, limit controls and automatic operation. If problems
are encountered on initial installation the following should
be checked
1. Is the unit equipped for the gas being used?
2. Are all of the wires connected to the gas valve prop-
erly?
3. Is the venting system functioning? Check for spillage at
the diverter.
4. Is the gas inlet pressure proper? Read instructions for
minimum pressure.
B. It is necessary to use a millivolt meter to determine if the
power from the generator is adequate. 500 millivolts is normal
with the thermostat off and 140 millivolts minimum with
thermostat on.

OPERATING INFORMATION
SOME HELPFUL WARNINGS
• Use low heat output when children are nearby.
• Do not cover the floor register when the furnace or pilot is
turned on.
• Do not restrict the flow of air around the register by placing
a screen under it.
• Do not dry clothes or any objects by putting them on floor
register because this creates a fire hazard.
15
• Do not hang clothes or any object above or over floor register
because this too creates a fire hazard.
• During warm weather months, turn to full OFF position before
you cover the register with a rug, because this too creates a
fire hazard.
CAUTION
NEVER run your furnace with the lighter hole open or with a
broken lighter hole window. Exhaust gases can get into the living
area through an open lighter hole and be fatal.
C. This floor furnace cannot be expected to function properly if
exposed to wind as found when installed in a house supported
by pillars (open foundation). The wind is most harmful if it
can go beneath the front of the draft diverter and produce a
pressure directly on the outlet of the chamber. This wind can
result in pilot outage and a reduction in millivolts, causing
the valve not to open.
D. Good operation of the system is dependent on the pilot and
generator working properly. It is possible for the pilot to
require cleaning yearly. Replace pilot assembly if cleaning
does not produce proper flame. Replacement on generator
alone is not recommended.
E. Gas Valve will not open. To determine problem area:
1. By-pass thermostat on the wall.
2. By-pass thermostat at the valve.
3. By-pass limit and thermostat at the valve.
4. Check millivolts.
