14) CLEANING AND ANNUAL MAINTENANCE
This heater consists of multiple individual atmospheric burners. Due to the variation in tile porosity, there could be
color variations between the burners. This is natural and should not be a cause for concern during the initial
startup.
This heater must be cleaned and serviced at least once before the start of each heating season or at any time the
infrared emitter shows signs of collecting any foreign material on its surface or in the ports, or when anything
obstructs the venturi or the screen. Maximum heating efficiency and clean combustion will be maintained by
keeping the emitter and burner clean. To clean the heater, follow these instructions: 1. Turn off all electrical and
gas supply to the heater. 2. Clean the reflector. 3. Remove the main burner orifice and clean it thoroughly. 4.
Check the venturi opening to be sure it is clean. If there is any evidence of dirt accumulation in the venturi,
remove it.
15) BURNER OPERATION/TROUBLESHOOTING
A) IGNITION MODULE DIAGNOSTICS
The LED located on the ignition module (see Figure) will
flash ON for ¼ second, then OFF for ¼ second during a
fault condition. The pause between fault codes is 3
seconds.
LED Indication Error Mode
Steady On Internal Control Failure
2 Flashes Flame Sense Fault
3 Flashes Ignition Lockout
B) FLAME SENSOR TESTING
The flame current is the current that passes through the
flame from the sensor to the ground. The minimum flame
current necessary to keep the system from lockout is 0.7
microamps. To measure the flame current, connect an
analog DC microammeter to the FC- and FC+ terminals per
diagram. The meter should read 0.7 µA or higher when the
burner is running full on. If the meter reads below zero, the
meter leads are reversed. Disconnect power and reconnect
the meter leads for proper polarity.
