TROUBLESHOOTING Qualified Technicians Only
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) Smell of gas
6) A thin coating of black soot forms on the
window. NOTE: See page 19, Cleaning
Glass.
7) A white coating forms on windows, logs,
and / or inside walls of firebox.
8) 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.
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, or thermopile.
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 (Figure 11) and check electrical
connections.
• Refer to Control and Safety Systems
Wiring
Diagram.
Electrically
components one at a time and replace
defective item.
• 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, negative air
pressure inside building (with respect to
exhaust exit), or "down draft" situation.
Make appropriate 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.
