TROUBLESHOOTING
Note: In normal operation, LED blinks once
every two seconds; also, LED will be on
for one second after every valid command
received by the receiver/valve' these are not
error codes.
Failure codes can occur anytime after the pilot
burner is lit. Failure code timing is 1/4 second
on, 1/2 second off.
Sequence is failure code followed by LED not
blinking for four seconds.
In the event of multiple failure codes, the next
failure code follows the previous failure code
by approximately 3 seconds.

LED Failure Codes and Service Action
WARNING: Turn off and unplug heater and let cool before servic-
ing. Only a qualified service person should service and repair heater.
IMPORTANT: Valve system troubleshooting should only be accom
-
plished by a qualified service technician.
Note: Before troubleshooting the gas control system, be sure external gas shut off valve
(located at gas supply inlet) is in the "ON" position.
POSSIBLE CAUSE
REMEDY
OBSERVED PROBLEM
1. Defective ignitor (no spark
at electrode)
2. Defective or misaligned
electrode at pilot (spark
at electrode)
3. Gas supply pressure
errant
4. Pilot orifice plugged
Spark ignitor will not light pilot
after repeated triggering of
ignitor button
1. Check for spark at elec-
trode and pilot; if no spark
and electrode wire is prop
-
erly connected, replace
ignitor
2. Using a match, light pilot.
If pilot lights, turn off pilot
and trigger the ignitor but-
ton again. If pilot lights,
an improper gas mixture
caused the bad lighting
and a longer purge period
is recommended. If pilot
will not light, check gap at
electrode and pilot - gap
should be 1/8" to have a
strong spark. If gap mea-
sures 1/8", replace pilot
3. Check inlet gas pressure. It
should be within the limits
as marked on the rating
plate
4. Clean or replace pilot orifice
