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 regulator 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. (check voltage within 5 sec.)

Listen to, and feel pilot solenoid 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 between 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.
