NOTE:
If the appliance does not operate, follow the instructions “To
Turn Off Gas to Appliance” printed below (and on the Operating Label
on the heater) and call your service technician.
10. Thermostat calls for heat, energizing the venter motor.
11. Venter pressure switch closes, firing the unit.
12. Burner flame is sensed, and in 30 seconds after the gas valve is
energized, the fan motor is energized.
13. If the flame is extinguished during the main burner operation, the
integrated control system closes the main valve and must be reset by
interrupting power to the control circuit. (See lighting instructions on
the heater.).

DANGER:
The gas burner in this gas-fired equipment is designed and equipped to provide safe
controlled complete combustion
. However,
if the installation does not permit the
burner to receive the proper supply of combustion air, complete combustion may
not occur. The result is
incomplete combustion
which produces carbon monoxide,
a poisonous gas that can cause death. Safe operation of indirect-fired gas burning
equipment requires a properly operating vent system that vents all flue products to
the outside atmosphere. FAILURE TO PROVIDE PROPER VENTING WILL RESULT
IN A HEALTH HAZARD WHICH COULD CAUSE SERIOUS PERSONAL INJURY OR
DEATH.
Always comply with the combustion air requirements in the installation codes.
Combustion air at the burner should be regulated only by manufacturer-
provided equipment. NEVER RESTRICT OR OTHERWISE ALTER THE SUPPLY
OF COMBUSTION AIR TO ANY HEATER. MAINTAIN THE VENT/COMBUSTION AIR
SYSTEM IN STRUCTURALLY SOUND AND PROPER OPERATING CONDITION.
