13) SEQUENCE OF OPERATION

The chart below shows the sequence of operation for the normal operating cycle of the heater when

connected to a permanent 120V power supply and the heater is turned on and off by a remote 120V

thermostat. (See Section 10)

If the flame is not sensed during sequence T2 then the burner will automatically begin re-ignition

sequence T1. The ignition sequence will be repeated three times with a 15 second inter-purge. If the

flame is not reestablished the heater will go to lockout.

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.
