Turning on the Main Burner
Follow the instructions provided by the appliance
manufacturer or turn up the thermostat to call for heat. If
the main burner does not light, refer to the
troubleshooting table.
Perform Gas Leak Test
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.
1. Check for gas leaks with soap and water
solution every time work is done on a gas
system.
2. Stand clear of the main burner when lighting it
to prevent injury from hidden leaks that could
cause flashback.
Gas Leak Test
1. Paint the pipe connections located upstream from
the ignition system control with a rich soap and
water solution.
Bubbles indicate a gas leak.
2. If a leak is detected, tighten the pipe connections.
3. Repeat steps 1 and 2 until no leaks are detected in
that area.
4. Light the main burner.
5. With the main burner in operation, paint the pipe
joints, adapters, and control inlet and outlet with a
rich soap and water solution.
6. If a leak is detected, tighten the adapter screws,
joints, and pipe connections.
7. Repeat steps 5 and 6 until no leaks are detected.
8. Replace the part with the same model number if
any leak cannot be stopped.
Adjust the Pilot Flame
The pilot flame should envelop 3/8 in. to 1/2 in. (10 cm to
13 cm) of the tip of the flame rod, as shown in Fig. 12.
1. Remove the pilot adjustment cover screw.
2. Turn the inner adjustment screw clockwise to
decrease or counterclockwise to increase the pilot
flame.
3. After adjusting the flame, replace and tighten firmly
the cover screw to prevent gas leakage.
NOTE: Controls are provided with adjustment screws
set at the maximum pilot flow position.
