TROUBLE SHOOTING GUIDE
SYMPTOM PROBLEM TEST SOLUTION
BEFORE ATTEMPTING TO TROUBLESHOOT, PURGE YOUR UNIT AND INITIALLY LIGHT THE PILOT AND THE MAIN BURNER WITH THE GLASS DOOR REMOVED.
Flames are consist-
ently too large or too
small. Carboning oc-
curs.
- 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. Gauge should
read 7" (minimum 4.5") water column for natural gas or 13" (11" minimum) water
column for propane. Check that main burner is operating on "HI".
Outlet pressure can be checked the same as above using screw (B). Gauge
should read 3.5" water column for natural gas or 10" water column for propane.
Check that main burner is operating on "HI".
AFTER TAKING PRESSURE READINGS, BE SURE TO TURN SCREWS CLOCK-
WISE FIRMLY TO RESEAL. DO NOT OVERTORQUE.
Leak test with a soap and water solution.
Unit is over-fi red or under-fi red.
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 extin-
guishes, especially when main burner ignites. Monitor appliance supply working
pressure.
- check if supply piping size is to code. Correct all undersized piping.
