The correct sparkgap should be 7/64" to 1/8".22. The pilots must be securely mounted relative to the main burner in such a position that main burnerignition will occur with minimum delay with a low pilot flame just sufficient to open the main gas valve.23. If the pilot fails to light when the control circuits are closed it may require manual resetting. Always waitat least 5 minutes before resetting the system. To reset turn the main switch to pump #1/only, then backto burner #2.

If delay is longer adjust the pilot and check spark gap (7/64").NOTE: When the trigger gun is released for more than 4.5 minutes the machine will shut off. Youmust turn the control switch to the "OFF" position then "ON" to restart.
