SECTION II: INITIAL START UP
OPERATION OF BURNER (DIRECT SPARK IGNITION)
Starting the Burner:
1.
Depress the gas valve control knob on the combination gas valve and turn to “OFF” (See Figure 13).
2. Set the room thermostat above room temperature and let the burner run five minutes to purge the appliance.
3. Set thermostat below room temperature.
4. Turn gas control valve knob to “ON”.
5. Set room thermostat higher than room temperature so that the burner will start.
To put burner out of operation
1.
Depress the gas valve control knob on the combination gas valve and turn to “OFF”.
2. Turn off electrical supply.
BURNER OPERATION
On every call for heat (system start), the ignition control performs a 30 second pre-purge. Upon completion of the pre-purge, the
ignition control opens the gas valve operator in the gas control. This allows gas to flow to the burner. Simultaneously, the electronic
spark generator in the control produces a spark pulse output. This voltage produces a spark at the burner igniter-sensor rod, igniting the
gas flowing around the electrode. If flame is not detected during the trial for ignition, the ignition control will go into a “lock-out”
condition. If this occurs, proceed to the section titled SAFETY LOCK-OUT TIME.
SAFETY LOCK-OUT TIME
The trial for ignition timer circuit starts timing the moment the trial for ignition starts. If the designated trial for igni tion time expires prior
to the detection of a flame, the ignition control will go into a “lock-out” condition. Before another attempt to start the burner can be
made, the ignition control must be reset. Reset by adjusting the thermostat or controller below room temperature, or to its “ OFF”
position. An alternate method is to shut the system power “OFF”. Wait at least one (1) minute and then turn the system “ON”.
If normal ignition does not occur, use Section V: Servicing and Troubleshooting to determine the problem.
