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
Ignitor will not spark or pilot will not light
Pilot will not stay lit
No gas to burner, although wall switch and
valve are set to the ON position
POSSIBLE CAUSE
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. Loose wiring on ignitor wire to ignition
module and/or poor ground to ignition
module
2. Pilot flame too low to sense
1. Wall switch wires defective or too long
2. Thermopile not generating sufficient volt-
age
REMEDY
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 re-
peated 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 pres-
sure
5. Have a qualified technician replace pilot
line
6. Replace control valve (refer to Replace-
ment Parts, page 19)
7. Check that main power is on and that all
wire connections are made correctly to
ignition model (see Wiring Diagram, page
18). Check for 24 VAC at the secondary
side of transformer. If 24 VAC is present
and module does not operate, have mod-
ule replaced otherwise have transformer
replaced
8. Open vent damper until fully locked in
OPEN position
1. Check wiring connection. Refer to wiring
diagram, page 18, 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
1. Check electrical connections
2. Recheck problems 1 and 2
