Flame Rollout Switch
All units are equipped with a temperature activated manually reset
switch. The flame rollout switch is centered above 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.

The heater has a 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.

THE OPERATING VALVE IS THE PRIME
SAFETY SHUTOFF. ALL GAS SUPPLY
LINES MUST BE FREE OF DIRT OR SCALE

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.
