Maintenance
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service techni-
cian. Propermaintenance and usewill require
more frequent, less extensive inspections and
servicing by the homeowner.
Generally, annual inspections should be per-
formedbyaqualifiedservicetechnician. More
frequent periodic inspections and cleanings
should be performed by the homeowner. Any
discrepancies discovered by the homeowner
should result in a call to a qualified service
technician to effect the repair or correction.
Refer to the maintenance schedule for mainte-
nance tasks, procedures, periodicity and by
whom they should be performed.
IMPORTANT: TURNOFFGASANDANYELEC-
TRICAL POWER BEFORE SERVICING THE
APPLIANCE.
MANUALLY-RESET BLOCKED FLUE SAFETY
SWITCH
This appliance is equipped with a manually-
reset blocked flue safety switch. Refer to
Figure 7 for its location. If during appliance
operation, the flame goes out (independently
of the burner on/off wall switch), it may be due
to the operation of this safety limit switch.
First allow the appliance to cool. Then reset
the safety switch by pushing the red reset
button on the back of the switch.
CAUTION: THE ELECTRONIC APPLIANCE
SHOULD BE TURNED OFF BEFORE REMOV-
ING THE LIMIT SWITCH.
To access the safety limit switch reset button,
remove the two screws. Pull out limit switch
withlowvoltage wiresattached,push thereset
button, then reinstall the limit switch. At this
time turn the electronic appliance back on.
The appliance should then relight and remain
lit. If this does not occur, turn off the appli-
ance and call a qualified service technician.
Burner Adjustments
Flame Appearance and Sooting
Proper flame appearance is a matter of taste.
Generally most people prefer the warm glow of
a yellow to orange flame. Appliances operated
with air shutter openings that are too large, or
with long vertical vent runs, will exhibit flames
that are blue and transparent. These weak, blue
and transparent flames are termed anemic.
Adjustment
To adjust the flame, position the air shutter to
the nominal setting
(Figure 8 ). Allow the
burner to operate for at least 30 minutes.
Observe the flame continuously. If it appears
weak or sooty as previously described, adjust
the air shutter open or closed until desired
effect is achieved.

If the air shutter opening is too small sooting
may develop. Sooting is indicated by black
puffsdevelopingat thetipsof verylongorange
flames.Sootingresultsinblackdepositsform-
ing on the logs, appliance inside surfaces and
onexterior surfaces adjacentto thevent termi-
nation. Sooting is caused by incomplete com-
bustion in the flames and a lack of combustion
air entering the air shutter opening.
To achieve a warm yellow to orange flame with
an orange body that does not soot, the shutter
opening must be adjusted between these two
extremes.
No smoke or soot should be present. Reposi-
tion the log set if the flames impinge on any of
them.
If sooting conditions exist, the air shutter
opening on the main burner can be adjusted.
Normally, the more offsets in the vent system,
the greater the need for the air shutter to be
opened further.

The logs are packaged within the firebox.
The bag of rockwool is in the lower control
compartment. Remove the rockwool from
the packaging and tear into dime size pieces
(Figure9) .Spread across the burner infront
of the front log. See Figure 10. Do not use
more than is necessary to cover the burner.
When properly positioned, the rockwool will
unevenly cover approximately 85% of the
front of the burner with no appreciable gaps.
Theseappliances areequipped with abeautifully
crafted four (4) piece ceramic fiber log set. The
logs, shown in

Millivolt Appliance Checkout
The gas control system on these appliances is
a millivolt standing pilot type. It consists of a
pilotburner, a piezo ignitor, a gas control valve,
a burner assembly and an ON/OFF wall switch.
A temperature limit switch is wired in series
with the millivolt wall switch and gas control
valve. If a higher than normal temperature is
sensed due to a blocked vent or prolonged
downdraft, the limit switch will open and cause
the burner to shut off.
The pilot flame should be steady, not lifting or
floating. Flame should be blue in color with
traces of orange at the outer edge.
The top ³⁄₈" (9 mm) at the pilot generator
(thermopile) should be engulfed in the pilot
flame
(Figure 11).
Figure 11
If the pilot flame pattern is not as shown in
Figure 11 , adjust it as follows:
1. Remove the pilot adjustment cap located on
the main gas valve.
2. Adjust the pilot screw to provide properly
sized pilot flame
(Figure 10 ) . Turn counter
clockwise to enlarge pilot flame and clockwise
to reduce the pilot flame. DO NOT attempt to
adjust pilot flame more than one half turn.
3. Replace the pilot adjustment cap.
Replace logs if removed for pilot inspection.
To light the burner; rotate the gas valve control
knobcounterclockwisetothe“ON”positionand
then turn “ON”the remote wall switch.
Electronic Appliance Checkout
The gas control system on these appliances is
an electronic low voltage gas control valve with
an intermittent ignitor. It consists of a low
voltage gas control valve, an intermittent igni-
tionsystem,anelectroniccontrolmodule,trans-
former and a burner assembly. A temperature
limit switch is wired in series with the gas
control valve. If a higher than normal tempera-
ture is sensed, due to a blocked vent or pro-
longed downdraft, the limit switch will open
and cause the burner to shut off.
The pilot flame should be steady, not lifting or
floating. Flame should be blue in color with
traces of orange at the outer edge.
To light the burner, push the gas control lever
in and toward the left to the “ON”position.

TROUBLESHOOTING THE MILLIVOLT GAS CONTROL SYSTEM
Note: Before troubleshooting the gas control system, be sure external gas shut off valve (located at gas supply inlet) is in
the “ON”position.
Important: Valve system troubleshooting should only be accomplished by a qualified service technician.
CORRECTIVE ACTION
SYMPTOM
A. Defective Ignitor
(no spark at electrode)
B. Defective or misaligned
electrode at pilot (spark at
electrode).
C. Gas supply pressure errant.
D. Pilot orifice plugged.
A. Defective pilot generator
(thermopile) or remote wall
switch wiring.
B. Defective automatic valve
operator.
C. Defective limit switch.
A. Wall switch or wires
defective.
B. Pilot generator may not be
generating sufficient
millivoltage.
C. Plugged burner orifice.
A. Pilot flame may be too low or
blowing (high) causing the pilot
safety to drop out.
Check for spark at electrode and pilot; if no spark and electrode wire
is properly connected, replace the ignitor.
Using a match, light pilot. If pilot lights, turn off pilot and trigger the
red button again. If pilot lights an improper gas mixture caused the
bad lighting and a longer purge period is recommended. If pilot will
not light check gap at electrode and pilot - should be ¹⁄₈"
(3 mm) to have a strong spark. If gap measures ¹⁄₈", replace pilot
assembly
(Figure 11 on page 7) .
Check inlet gas pressure. It should be within the limits as marked on
the rating plate.
Clean or replace pilot orifice.
Check pilot flame. It must impinge on pilot generator
(Figure 11 on
page 7) . Clean and/or adjust pilot for maximum flame impingement
on generator.
Be sure wire connections from generator at gas valve terminals are
tight and generator is fully inserted into the pilot bracket.
One of the wall switch wires may be grounded. Remove wall switch
wires from valve terminals. If pilot now stays lit, trace wall switch
wires for a ground. May be grounded to appliance or gas supply.
With pilot operating (lit), check pilot generator with a millivolt meter.
Take reading at generator terminals of gas valve. Should read 325
millivolts minimum while holding valve knob depressed in pilot
position and wall switch “OFF.”Replace faulty generator if reading
is below specified minimum.
Turn knob to “ON,”place wall switch to “ON.”Millivolt meter should
read greater than 100mV. If reading is OK and the burner does not
come on, replace the gas valve.
Reset the limit switch button. If still not working, isolate the limit
switch. Disconnect the wires from the “ON/OFF”switch and the valve
(label wires for reattachment). Test for continuity with a multimeter.
Ifcontinuity isnot indicated, switch is defectiveand mustbe replaced.
Check wall switch and wires for proper connections. Place jumper
wires across terminals at wall switch. If burner comes on, replace
defective wall switch. If OK, place jumper wires across wall switch
wires at gas valve. If burner comes on, wires are defective or
connections are bad.
Re-check Symptom #2.
Check burner orifice for blockage and remove.
Clean/adjust pilot flame for maximum impingement on pilot genera-
tor
(Figure 11 on page 7) .
POSSIBLE CAUSES
1. Spark ignitor will not
light pilot after repeated
triggering of red button.
2. Pilot will not stay lit
after carefully following
lighting instructions.
3. Pilot burning, no gas to
burner, valve knob “ON,”
wall switch “ON.”
4. Frequent pilot outage
problem.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
TROUBLESHOOTING THE ELECTRONIC IGNITION SYSTEM
N ote: Before troubleshooting, be sure that the appliance main line gas shut-off valve, the gas control valve and the wall switch are in
the “ON”position.
Important: “ON/OFF”switch must be “OFF”before performing continuity test. Adjust multimeter to the ohm setting when performing continuity tests.
Important: Valve system troubleshooting should only be accomplished by a qualified service technician.
Confirm 24Vac output from transformer (red and blue leads). If no, then replace
transformer.
Note: Before replacing transformer check wiring for loose connections or broken wires
and repair as needed. Turn off power before replacing transformer.
Disconnect the two black wires from the two red wires attached to the limit switch and
transformer (label wires for correct reattachment). Test “ON/OFF”wall switch for
continuity with a multimeter. If continuity is not indicated, switch is defective and must
be replaced.
Note: Before replacing “ON/OFF”switch be sure to check switch wiring for loose
connections or broken wires and repair as needed.
Resetthelimitswitchbutton. Ifstillnotworking,isolatethelimit switch in the same manner
as the “ON/OFF”switch (label wires for correct reattachment) and test for continuity with
a multimeter. If continuity is not indicated, switch is defective and must be replaced.
If reading is not 24V at “TH”and “TR”terminals on ignition control, replace ignition
control module.
Check for availability of gas at control. Check that manual valve upstream of gas control
and manual valve on gas control are in the full “ON”position. Check for plugged pilot
orifice or plugged pilot tubing. Also check pilot key adjustment at gas control valve.
Confirm 24Vac at gas valve terminals “C”and “P”of the gas valve. If yes, valve is OK. If
no voltage, check the wiring. If wiring tests OK, check ignition control module.
Confirm24Vacat “PV”and “PV/MV”on ignition control module. If no,replacetheignition
control.
Check if pilot line and pilot orifice are plugged. Clean or replace as necessary. Adjust pilot
flame if necessary.
Confirm that the igniter is sparking at the pilot assembly when the “ON/OFF”switch is
activated. If not, undertake the following steps:
With“ON/OFF”switch “OFF,”remove wire at “TR”terminalat the ignition control module.
Disconnect the electrode wire “IGN”at the ignition control. Connect one end of a jumper
wire to the metal blade of a small screwdriver. Attach the other end of the jumper wire to
any metal part of the chassis. Reconnect the “TR”terminal. Position end of metal blade
approximately ¹⁄₈" (3 mm) from the “IGN”terminal. Activate the “ON/OFF”switch.
Sparking should occur between the “IGN”terminal and screwdriver blade. If sparking
does occur, the ignition control module is OK, but either the electrode wire of the igniter
is faulty and the pilot and electrode assembly should be replaced.
Electrode tip needs to be realigned to correct location. ³⁄₃₂" to ¹⁄₈" (2 –3 mm) gap between
electrode tip and pilot hood is desired.
Pilot and electrode igniter must be properly aligned so that the pilot flame impinges the
top ³⁄₄" (19 mm) of the electrode igniter. The electrode igniter must be pushed all the way
into the pilot bracket. Adjust pilot flame if necessary.
Check main burner orifice(s) for stoppage. Clean or replace.
Check for 24 volts at gas operator terminals “M”and “C.”If there is a 24V reading and the
burner does not come on, the valve operator is defective and the gas valve must be
replaced.
Adjust pilot flame and/or check location of electrode igniter.
SYMPTOM CORRECTIVE ACTION
1. No spark and no pilot gas.
2. Spark but no pilot gas
(no solenoid valve click).
3. Spark but no pilot gas
(solenoid valve click).
4. Pilot gas available, but
pilot does not light
(solenoid click).
5. Pilot burning but main
burners will not come on.
Note: Wait at least 90
seconds after pilot lights
before doing the checkout
for possible causes.
6. Burners come “ON”but go
“OFF.”
A. Faulty transformer.
B. “ON/OFF”switch defective.
C. Limit switch defective.
D. Ignitioncontrolmoduledefective.
A. No gas supplied to pilot valve.
B. Faulty gas valve.
C. Ignitioncontrolmoduledefective.
