TROUBLESHOOTING
PROBLEM
1) Pilot will not light, and Piezo Igniter does
not produce a heavy blue spark.
2) Pilot will not light, but Piezo Igniter pro-
duces a heavy blue spark.
3) Pilot will not stay lit.
4) Pilot flame stays lit, but main burner will
not light.
5) Main burner stays lit for up to 10 minutes
and then shuts off, pilot flame remains lit.
6) Smell of gas
7) A thin coating of black soot forms on the
window. NOTE: See page 16, Cleaning
Glass.
8) A white coating forms on windows, logs,
and / or inside walls of firebox.
9) Circulation blower makes a humming
sound, but there is no circulation air.
REFERENCE INFORMATION FOR QUALIFIED TECHNICIAN:
Thermopile / Thermocouple Operation
Thermopile: Millivolt production should be a minimum of
325 MV with pilot only.
Thermocouple: Millivolt production should be a minimum of
14 MV with pilot only.
Qualified Technicians Only
CAUSE(S)
a. Electrode wire (at Piezo Igniter) not
pushed completely on.
b. Piezo igniter is defective
a. Incorrect lighting procedure.
b. No gas to appliance due to shut valves or
disconnected gas lines.
a. Thermocouple is not firmly connected to
control valve.
b. Pilot flame is not directed to top of ther-
mocouple.
c. Thermocouple is defective. Make sure
connection is solid.
a. Burner control switch (on control panel) is
in "OFF" position; or thermostat (if in-
stalled) is turned off or temperature set-
ting is too low.
b. Electrical wiring is damaged or poorly
connected
c. One of the following components may be
defective: burner control switch, thermo-
stat, vent spill switch, or thermopile.
a. Vent is blocked; flue gas is "spilling",
which activates the spill switch and shuts
down the appliance.
b. The house is negatively pressurized re-
sulting in spill switch activation.
a. Loose fittings may be allowing gas to leak
out.
a.
Burner primary air inlet is restricted or
blocked.
b.
Flames make contact with logs or other
surfaces.
c.
Improper venting.
a. Residues / impurities being burned off.
a. Impeller blades in circulation blower are
dirty.
b. Circulation blower is defective.
Drop out rate
TP 50-60 MV
TP 1 1/2-2 Min. (3 max.) if longer, replace thermopile.

SOLUTIONS
Make sure connections are solid.
Replace piezo igniter.
Carefully follow the lighting / operating
instructions found in the appliance of this
owner's manual.
Check for multiple gas shut-offs; check
gas supply lines.
Ensure thermocouple is fully inserted into
pilot assembly.
Replace thermocouple.
Position the burner control switch to
"ON"; or adjust the thermostat. Refer to
manufacturer's instructions for thermo-
stat.
Refer to Control and Safety Wiring Dia-
gram (page 18) and check electrical
connections.
Refer to Control and Safety Systems
Wiring Diagram (page 18). Electrically
bypass components one at a time and
replace defective item.
Examine venting system for blockage.
Remove any blockage.
Open a window to see if the problem is
corrected.
Check all joints for leakage: pilot assem-
bly, gas supply system, main burner as-
sembly, pilot and burner adjustment
screws. Use a proper leak check solu-
tion. WARNING: Never use an open
flame to check for leaks.
Be sure all openings (fresh air inlets) in
stove are free from dust and debris. Re-
check these areas periodically.
Make sure ceramic logs are in their cor-
rect positions.
Check for flue blockage, disconnected
flue, improper installation. Make appro-
priate corrections.
Follow cleaning guidelines outlined in the
MAINTENANCE section of this manual.
Disconnect electrical power to circulation
blower, access blower and clean impeller
blades as outlined in the MAINTE-
NANCE section of this manual.
Replace blower.
