•Check for spark: Spark cannot be seen through the sight glass. When display shows “ignition” do you have flame?
Yes – If flame is present then igniter does not need to be checked any further.
If No – To verify spark at igniter, turn gas off, remove igniter, leave wires connected, recycle heater and look for
spark at igniter rods. If no spark is present, confirm the spark gap is approximately 3/16
th
at tip of rods. Clean igniter
rods with an abrasive material such as emery cloth, steel wool, etc. and repeat check for spark. If still getting no spark,
disconnect igniter cable from main control board. Hold igniter cable approximately an 1/8
th
of an inch from spark
terminal on the board. Cycle the unit back on and check for spark from board when the display showing “ignition”. If
no spark is present from the board to the cable, replace the ignition control board. If spark is present from board to
cable, replace the igniter assembly.
•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 kits 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.
•Flame recognition: If the unit fires and goes out then the board does not sense flame.
Confirm flame rod wire is secure
at board and wire is not damaged. Turn unit off, remove and clean flame rod with an abrasive material such as emery
cloth, steel wool, etc. If possible, measure flame current (minimum flame current for board to sense flame is 0.5uA).
minimum flame current is present and code continues, replace control board.
•Gas valve adjustment: MUST BE DONE WITH COMBUSTION ANALYZER. See page 48.

Error A001 Ignition Lockout
This unit has failed ignition 27 consecutive cycles. The unit will fail nine times and give an A029. It will fail 9
more times and give an A029. On the 27
th
failure, the unit will lock out with an A001 code.
The only visible check is to look through the sight glass window into the combustion chamber. The sight glass is
located on the mounting plate next to the igniter and flame rod. ANY flame, no matter how long, means the igniter
and gas valve are both operational.
