FAULT
Check for 14V at
Transformer
Check for 14V at
Control Box
Check for breaks in Pilot
Igniter
Check Pilot Igniter wiring &
Connector
Is pilot valve opening?
Ensure pilot flame
is impinging on the
thermocouple
Is the thermocouple
securely connected to the
control box?
LED flashing 3 times, no
recycle?
LED flashing 4 times, no
recycle? (Flame sense fault)
LED flashing 5 times, no
recycle? (Valve Fault)
Shuts down before main
burner lights
Shuts down after being on
for several minutes or hours
and does not re-light
Unit shuts down for 1

ACTION(S)
Make sure transformer is powered. If so, replace
transformer.
Check wiring for continuity, replace if broken.
Ensure wire is <50 feet long and 12AWG minimum
(smaller number is bigger wire). Replace with
larger wire or shorten length. Replace with
correct wiring if incorrect.
Replace Pilot Igniter.
Repair.
Check input gas pressure. Maximum pressure 1/2
PSI. Install regulator if higher.
Check voltage to pilot valve. Voltage should read
>10.2VDC. Check "No or Low Voltage" above if
less.
Check pilot coil for open circuit. Replace pilot
valve if open.
Ensure air has been bled from gas line
Consult burner manufacturer for minimum gas
pressure
If natural gas, ensure pilot jet is not for LP
Check pilot injector for clogged jet. Clean or
replace.
If pilot can be lit with a match, check igniter
position and adjust, or check "No or Low Voltage"
above.
Check for clogged pilot or injector and clean.
Check for correct pilot injector. (LP or NG)
Tighten Connection
Replace Thermocouple
Maximum flame losses per heat cycle exceeded.
Recycle power to reset.
Ensure pilot flame is impinging on the
thermocouple and is adequately sheltered from
the wind. If impingement is consistent and no
wind present, replace thermocouple.
Turn power off for 10 seconds and back on. If
persistent, replace control module.
Turn power off for 10 seconds and back on. If
persistent, check "No or Low Voltage" above. If
voltage is okay, replace control module.
Check "No or Low Voltage" above.
Over temperature - ensure control compartment
remains under 175° F. If continued operation
above this temperature, life of product will be
reduced.
This is normal operation for validation of safety
circuitry.
