Error A002 Flame is Not Stable
This alarm code means the unit had flame rectification within one heating cycle; but lost the flame
rectification signal three times within one call for heat. Causes of this issue are: Incorrect gas pressure or gas
supply issues, incorrect vent terminations, restricted exhaust vent, dirty flame rod.
•
Check for water in combustion chamber Remove igniter and flame rod, shine a light through one hole while
looking through the other, or, remove only the igniter and use something (wire, copper tubing, a 1/2” tape
measure will fit) to insert into the hole that will reach the bottom of the chamber (4ft deep or more). Insert till it
stops, remove, is it wet? How many inches of the object is wet? Up to 6 inches of water could be a result of
condensation forming from short cycling but all water must be removed for proper operation. Larger amounts
of water may be suspect for tank leak.
•
Incorrect gas pressure: See page 47 for instructions on checking gas pressure.
•
Check condensate drain line: Condensate that is not draining properly will back up into the exhaust elbow,
restricting the exhaust vent. Is the drain line configured per the Use & Care Manual? THERE SHOULD BE
NO TRAP OR NEUTRALIZER KIT IN THE CONDENSATE RUN. Does condensate line maintain at least
1/4” per foot fall to drain? Runs than cannot maintain at least 1/4” per foot fall and/or are over 15ft in distance
must utilize a condensate pump. If pump is being utilized, is it working?
•
Check venting: Are intake and exhaust vent runs within maximum allowances? Are there any horizontal runs
that may be pitched incorrectly and holding water/debris to create restriction? Is exhaust vent pushed too far
down into the grey exhaust tee? Venting should not go more than 2 inches into the tee.
•
Verify vent terminations: . If concentric vent kit is being used, remove intake vent from heater and recycle. If
no error occurs with intake removed then issue is with the concentric vent kit. Common issues are: kit
connected with intake and exhaust reversed, center pipe missing or loose, non-approved vent kit being used.
•
Check gas valve adjustment: Should only be performed with a combustion analyzer . See page 47.

Troubleshooting Error Codes
Error A003 Intake Switch Open
The intake pressure switch is a normally closed switch. It should only open if there is a blockage/restriction in
the intake venting.
•
Check wiring to the switch to ensure no wires have been broken, damaged or disconnected.
•
Confirm tubing from switch to the air intake is properly connected and not damaged.
•
With unit off, remove wires from intake switch and check for continuity. If continuity is not present, replace
the intake switch.
•
If continuity is present, cycle power back on and clear alarm code. If switch opens (loses continuity) with
blower running, then switch is operating normally and there is something causing vent restriction.
•
Remove the air intake pipe from the rubber fernco connector at blower, if unit will fire with venting
removed then issue is in venting.
•
If error persists with intake removed from blower, verify no debris in blower housing. If no debris found
and switch still opens with intake venting removed, replace the intake pressure switch.
