Starting a Conversion Gas Burner (Pilotless)
Most of the instructions given in the previous section for starting a conversion gas burner equipped with a pilot light will also apply here. The major difference is the use of direct spark ignition rather than a pilot flame.
The basic procedure for starting a pilotless conversion gas burner is as follows (Figure 16-14):
1. Check the piping for leaks.
2. Bleed (purge) the gas line.
3. Set the air shutter about three-quarters open.
4. Depress the valve dial and turn it on the ON position.
5. Turn on the main line switch.
6. Set the room thermostat above the room temperature. This should cause the burner motor to start. If it does, burner ignition should occur after 30 seconds.
7. If the burner fails to light, turn off the main line switch and then turn it on again.
8. Readjust the air shutter for a quiet, soft flame. The flame should be blue at the burner, changing to orange at the tips.
9. Start and stop the burner several times with the thermostat to check its operation.
