Did the Damper Assembly
fully open?
Check Damper for obstruc-
tions—remove if necessary. Did Damper fully open?
1. Remove Ignition Cable and check for
good continuity, replace if necessary.
2. Check Ignitor Electrode gap for
proper spacing (1/8” to 5/32”). Correct if necessary.
3. Examine Ceramic Insulator on Pilot
Assembly for cracks. Replace if cracks are evident.
If all of the above components check okay, replace Ignition Control Module.
Is 24 VAC present between the
Gray ground wire and the Red 24 V wire connected to the Ignition Control Module?
Check continuity of Red
and Gray wires between Damper Assembly and Ignition Control Module. Is continuity “good”?
Remove Damper Drive
Motor cover; is the green “CALL FOR HEAT” LED illu- minated?
Damper Assembly is defective and must be replaced. The water heater may still be used until a replacement Damper Assembly can be installed by following these steps:
Turn off power to the water heater at the main power switch located on the side of the control enclosure. Order a replacement Damper Assembly.
Honeywell Damper: With power still off, remove Damper Drive Motor cover and move the Service Switch located to the right of the motor from th “NORMAL” position to the “SERVICE
position. Using a standard flat screwdrive, rotate the slotted white knob, located below the motor, counter-clockwise until the damper blade is in the open (fully vertical) position. Replace
cover.
Effikal Damper: With power still off, move the Service Switch located on the left side of the control enclosure from the “NORMAL” position to the “SERVICE” position. With pliers secured
on the damper shaft near the controller, rotate the damper counter-clockwise until the damper is in the fully open (fully vertical) position.
All Dampers: Turn power on at the main power switch located on the side of the control enclosure. The heater should now attempt its firing sequence. * Denotes these boxes are for use with the “Power Assist Burner & Xtreme models” only.
