TROUBLE SHOOTING LP Burner Spark Ignition
Turn power switch ON and
check for sparks at electrodes
at pilot light.
Switch OFF then ON again to
purge air from gas lines.
Check fuel supply and fuel
valve, check for 10 to 20 lbs on
regulator, repair or replace regula-
tor if necessary.
Check that the pilot valve is
open 4 to 6 turns.
Check for plugged pre-orifice
(located at the pilot valve)
Clean orifice with compressed air or
a .013" orifice cleaner.
Check pilot solenoid valve for
12 volts when power switch is
first turned ON.
Listen to, and feel pilot sole-
noid for activation when power
switch is first turned ON. If no
activation is observed
replace solenoid.
Pilot won't ignite Pilot ignites & then goes out.
(flame not sensed causing control to
lock out)
Check for sufficient flame to
be sensed.
•Check fuel pressure, 10-20
lbs nominal.
•Open pilot valve 4-6 turns.
•Check for plugged pre-
orifice (located at
the pilot valve) Clean orifice
with com-
pressed air or a .013" orifice
cleaner.
•Clean pilot orifice
Clean electrodes
with a fine grade of emery
cloth.
Check for proper
electrode gap.
of .125"+ .031
Replace electrodes
if out of spec.
Check for faulty wiring be-
tween sensing electrode and
ignition control. Check for poor
ground connections.
Check for a low battery or bad
fuse in control panel.
Check for 12-14 volts at red
wire at Ignition Control.
Check for faulty wiring
or a poor ground connection.
Check for low battery, bad
fuse in control panel, or faulty
wiring between solenoid and
ignition control.
Replace Ignition Control.
