SYMPTOM PROBLEM TEST SOLUTION

Pilot goes out while standing; Main burner is in ‘OFF’ position.

Gas piping is undersized.	- turn on all gas appliances and see if pilot fl ame fl utters, diminishes or
	extinguishes, especially when main burner ignites. Monitor appliance
	supply working pressure.
	- check if supply piping size is to code. Correct all undersized piping.

Flames are consis- tently too large or too small. Carbon- ing occurs.

- check pressure readings:

Inlet pressure can be checked by turning screw (A) counter-clockwise 2 or 3 turns and then placing pressure gauge tubing over the test point. Check with burner operating on “HI”. Gauge should read 7” (minimum 4.5”) water column for natural gas or 13” (11” minimum) water column for propane.

Outlet pressure can be checked the same as above using screw (B). Check with burner operating on “HI”. Gauge should read 3.5” water column for natural gas or 10” water column for propane.

AFTER TAKING PRESSURE READINGS, BE SURE TO TURN SCREWS CLOCKWISE FIRMLY TO RESEAL. DO NOT OVERTORQUE.

Leak test with a soap and water solution.
