Troubleshooting The Gas Control System - Barbara Jean OFP4336S1 Manual

Outdoor Burners - Troubleshooting the Gas Control System
NOTE: Before troubleshooting the gas control system, be sure external gas shut off is in the "ON" position.
Problem
Spark igniter will not
light
Pilot will not light
Pilot will not stay lit
after carefully
following lighting
instructions.
Pilot burning, no gas
to burner, Valve
knob "ON", Wall
Switch "ON"
Frequent Pilot
outage problem
Burners burn with
yellow flame,
accompanied by the
smell of gas.
Possible Causes
Defective or misaligned electrode
at pilot.
Defective igniter
(push-button)
Safety Switch is Depressed.
Defective Valve Magnet
Wall Switch or wires defective
Generator may not be generating
sufficient voltage
Plugged burner orifice
Defective automatic valve
operator
Pilot flame may be too low or
blowing (high) causing the pilot
safety to drop out
Windy Conditions
Possible spider web or other
debris.
Corrective Action
Check for spark at electrode and pilot: if no spark and
electrode wire is properly connected, replace igniter.
Using a match, light pilot, If pilot lights, turn off pilot and
push the red button again. If pilot will not light, check gap
at electrode and pilot- gap should be 1/8" to 1/4" to have
a strong spark.
Clear any obstructions and make sure Lever Arm is not
bent or damaged.
Turn valve knob "ON", place wall switch "ON". Millivolt
meter should read greater than 100mv. If the reading is
okay and the burner does not come on, replace the gas
valve.
Check wall switch and wires for proper connections.
Jumper wire across terminals at wall switch. If burner
comes on, replace defective wall switch. If okay, jumper
wire across wall switch wires at valve. If burner comes
on, wires are faulty or connections are bad.
Check generator with millivolt meter. Take reading at
generator terminals of gas valve. Should read 325
millivolts minimum while holding valve knob depressed in
pilot position and wall switch "OFF". Replace faulty
generator if reading is below specified minimum.
Check burner orifice for stoppage and remove.
Remove all switch wires from gas valve. Install jumper
wires from TPTH and TH terminals of gas valve. Turn
valve "ON". If main burner does not light, replace valve.
Clean and/or adjust pilot flame for maximum flame
impingement on generator.
-Move appliance to a less windy area if possible
-Use when conditions are less windy
-Install a wind guard
Thoroughly clean burner venturi.
