TROUBLESHOOTING
NOTE:
Before troubleshooting the system, make sure the gas shutoff valve is ON. The two most common causes of a malfunctioning gas
appliance are:
1. Loose wiring connections
2. Construction debris clogging the pilot and/or gas control valve filter
OBSERVED PROBLEM
POSSIBLE CAUSE
REMEDY
Igniter will not spark or pilot will not light
1. No gas supply or shutoff valve is OFF
2. Air in gas line
3. Construction debris clogging pilot orifice
4. Low gas pressure
5. Kinked pilot line
6. Control valve knob is not opening
7. No power to unit or the ignition module or
power transformer is bad
8. Vent damper not fully open
1. Check to see if you have gas supply and
that equipment shutoff valve is opened
2. Repeat lighting procedure several
times to purge all air out of lines. If
after repeated attempts appliance does
not light, call for qualified service and
repair
3. Remove debris and dirt, inspect and
clean any other possible obstructions
4. Contact your gas supplier to check
pressure
5. Have a qualified technician replace pilot
line
6. Replace control valve
(refer to Re-
placement Parts, Page 20)
7. Check that main power is on and that
all wire connections are made correctly
to ignition model
(see Wiring Diagram,
Page 19).
Check for 24 VAC at the sec-
ondary side of transformer. If 24 VAC is
present and module does not operate,
have module replaced otherwise have
transformer replaced
8. Open vent damper until fully locked in
OPEN position
Pilot will not stay lit
1. Loose wiring on igniter wire to ignition mod-
ule and/or poor ground to ignition module
2. Pilot flame too low to sense
1. Check wiring connection. Refer to wiring
diagram,
Page 19
, and/or check ground
wire to ignition module
2. Clean and adjust pilot burner and check
gas supply and inlet pressure to unit
NOTE:
Have a qualified technician
replace pilot assembly if broken or
corroded
No gas to burner, although wall switch and valve
are set to the ON position
1. Wall switch wires defective or too long
2. Thermopile not generating sufficient voltage
1. Check electrical connections
2. Recheck problems 1 and 2
