Flame Rollout Switch
All units are equipped with a temperature activated manually reset
switch. The flame rollout switch is located centrally on the top of
the burner assembly. It is factory set and is non-adjustable. If the
setpoint is reached, the flame rollout acts to interrupt the electric
supply to the gas valve. If the flame rollout switch activates,
identify and correct the cause before resetting the switch. Refer
to the Maintenance Section for information on probable causes
and instructions on resetting the flame rollout switch.
Burner
The heater has a one-piece burner designed to provide controlled
flame stability without lifting or flashback with either natural or
propane gas. The burner can be removed as a unit for inspection
or service.
Gas Valve
THE OPERATING VALVE IS THE PRIME
SAFETY SHUTOFF. ALL GAS SUPPLY
LINES MUST BE FREE OF DIRT OR SCALE
BEFORE CONNECTING THE UNIT TO
ENSURE POSITIVE CLOSURE. SEE HAZARD
INTENSITY LEVELS, PAGE 5.

Check Installation -
Check the installation prior to start-up:
1. Unit must be secure and level.
2. Verify proper clearances from combustibles.
3. Check vent and combustion air systems to be sure that they
are not blocked.
4. Check piping for leaks and proper gas line pressure. Bleed
gas lines of trapped air.
5. Check electrical wiring. Be sure all wire gauges are as
recommended. A service disconnect switch should be used.
Verify that fusing or circuit breakers are adequate for the
load use.
6. Verify that the return air duct connection is physically
sound, sealed to the unit cabinet and terminates outside of
the space containing the furnace.
7. Check that the vent connector is in place and is physically
sound without holes or excessive corrosion.
8. Check that flue product carrying areas external to the
furnace are clear and free of obstructions.
9. Check that there are no obvious signs of deterioration of the
furnace.
10. Check that the physical support of the unit and furnace are
sound without sagging, cracks, gaps, etc., around the base
so as to provide a seal between the support and the base
These examinations should be done by qualified service
personnel prior to initial start-up, and then at least on a yearly
basis.

This appliance does not have a pilot. It is equipped with
an ignition device that automatically lights the burner.

• Before operating, smell all around the appliance area
for gas. Be sure to smell next to the floor because some
gas is heavier than air and will settle on the floor.
