.
Valve.
Turn the valve knob to the ON position. Place the ON/OFF switch in
the ON position. Check the millivolt meter a the thermopile terminals.
The millivolt meter should read greater than 125mV. If the reading
is acceptable, and if the burner does not come on, replace the gas
valve.
D
.
Plugged burner orifice.
Check the burner orifice for stoppage. Remove stoppage.
E
.
Wall switch or wires.
Check the wall switch and wires for proper connections. Place the
jumper wires across the terminals at the wall switch. If the burner
comes on, replace the wall switch. If the wall switch is OK, place
the jumper wires across the wall switch wires at the gas valve. If the
burner comes on, the wires are faulty or connections are bad.
4
.
Frequent pilot outage
problem.
A
.
Pilot flame may be too high or
too low, or blowing out (high
pressure), causing pilot safety
to drop out.
Clean thermocouple and adjust the pilot flame for proper flame
impingement. Follow lighting instructions carefully.
5
.
The pilot and main
burner extinguish while in
operation.
A
.
No LP in tank.
Check the LP (propane) tank. Refill the fuel tank.
B
.
Improper gas inlet pressure.
Verify with manometer. NG should read 5-14 inches w.c. LP should
read 10-14 inches w.c.
C
.
Inner vent pipe leaking exhaust
gases back into the system.
Check venting system for damage. Replace/repair improperly
assembled pipe sections.
D
.
Glass installed improperly.
Check to ensure glass is installed properly. Replace glass panel
assembly.
E
.
Thermopile or thermocouple.
Replace pilot if necessary.
F
.
Improper vent cap installation.
Check for proper installation and freedom from debris or blockage.
G
.
High limit switch has been
automatically activated.
This appliance is equipped with an auto reset high limit switch
which will shut down the appliance if it spills under flue blockage or
excessive negative pressure conditions. Shut off the appliance and
the gas supply. Do not attempt to operate the appliance until it has
been examined by a qualified service technician.
6
.
Glass soots.
A
.
Flame impingement.
Adjust the log set so that the flame does not excessively impinge on
it. Refer to log instructions.
B
.
Improper air shutter setting.
Refer to manual for shutter set points. Ensure that set point is correct
for appliance/gas type. If unit has adjustable shutter, it may be
necessary to increase shutter opening.
C
.
Debris around air shutter.
Inspect the opening at the base of the burner. NO MATERIAL
SHOULD BE PLACED IN THIS OPENING.
7
.
Flame burns blue and lifts
off burner.
A
.
Insufficient oxygen being
supplied.
Ensure that the vent cap is installed properly and free of debris.
Ensure that the vent system joints are tight and have no leaks.
Ensure that no debris has been placed at the base of, or in the area
of the air holes in the center of the base pan beneath the burner.
Ensure that the glass is tightened properly on the unit, particularly on
top corners.
B. Intellifire Ignition System
Symptom
Possible Cause
Corrective Action
1
.
Pilot won’t light. The
ignitor/module makes
noise, but no spark.
A
.
Incorrect wiring.
Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor are
connected to correct terminals on module and pilot assembly.
B
.
Loose connections or electrical
shorts in the wiring.
Verify no loose connections or electrical shorts in wiring from module
to pilot assembly. Verify connections underneath pilot assembly are
tight; also verify connections are not grounding out to metal chassis,
pilot burner, pilot enclosure, mesh screen if present, or any other
metal object.
C
.
Ignitor gap is too large.
Verify gap of igniter to right side of pilot hood. The gap should be
approximately .17 inch or 1/8 in. (3 mm).
D
.
Module.
Turn ON/OFF rocker switch or wall switch to OFF position. Remove
ignitor wire “I” from module. Place a grounded wire about 3/16 in.
(5 mm) away from “I” terminal on module. Place ON/OFF rocker
switch or wall switch in ON position. If there is no spark at “I” terminal
module must be replaced. If there is a spark at “I” terminal, module
is fine. Inspect pilot assembly for shorted sparker wire or cracked
insulator around electrode. Replace pilot if necessary.
2
.
Pilot won’t light, there is no
noise or spark.
A
.
No power or transformer
installed incorrectly.
Verify that transformer is installed and plugged into module. Check
voltage of transformer under load at spade connection on module
with ON/OFF switch in ON position. Acceptable readings of a good
transformer are between 3.2 and 2.8 volts AC.
B
.
A shorted or loose connection
in wiring configuration or wiring
harness.
Remove and reinstall the wiring harness that plugs into module.
Verify there is a tight fit. Verify pilot assembly wiring to module.
Remove and verify continuity of each wire in wiring harness. Replace
any damaged components.
C
.
Improper wall switch wiring.
Verify that 110/VAC power is “ON” to junction box.
D
.
Module not grounded.
Verify black ground wire from module wire harness is grounded to
metal chassis of appliance.
E
.
Module.
Turn ON/OFF rocker switch or wall switch to OFF position. Remove
ignitor wire “I” from module. Place ON/OFF rocker switch or wall
switch in ON position. If there is no spark at “I” terminal module must
be replaced. If there is a spark at “I” terminal, module is fine. Inspect
pilot assembly for shorted sparker wire or cracked insulator around
electrode.
3
.
Pilot sparks, but Pilot will
not light.
A
.
Gas supply.
Verify that incoming gas line ball valve is “open”. Verify that inlet
pressure reading is within acceptable limits.
B
.
Ignitor gap is incorrect.
Verify that spark gap from ignitor to pilot hood is .17 in. or 1/8 in (3
mm).
C
.
Module is not grounded.
Verify module is securely grounded to metal chassis of appliance.
D
.
Module voltage output / Valve/
Pilot solenoid ohms readings.
Verify battery voltage is at least 2.7 volts. Replace batteries if voltage
is below 2.7.
