General Information
The fireplace models covered in this manual
are direct-vent sealed combustion gas fireplace
heaters designed for residential application.
These direct-vent appliances operate with the
combustion chamber completely isolated from
the indoor environment.
All air for combustion is brought in from the
outside and exhaust gases are vented through
the same direct-vent, co-axial (intake/exhaust)
vent system.
The Millivolt appliances have a millivolt gas
control valve with piezo ignition system. If any
optional accessories that will require electrical
power are to be installed, the electrical power
must be provided at the time of appliance installation.
The Electronic appliances have an electronic
intermittent pilot ignition system. External
electrical pow-er is required to operate these
appliances.
These appliances comply with National Safety
Standards and are tested and listed by OMNI-Test
Laboratories, Inc. (Report No. 116-F-48-5) to
ANSI Z21.88 (in Canada, CSA-2.33), and CAN/
CGA-2.17-M91 in both USA and Canada, as
vented gas fireplace heaters.
The Installation must conform to local codes
or, in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1/NFPA
54-latest edition, or the Natural Gas and Propane
Installation Code, CAN/CSA B149.1-latest edition. The appliance, when installed, must be
electrically grounded in accordance with local
codes or, in the absence of local codes, the
latest edition of the National Electrical Code,
ANSI/NFPA 70, or the Canadian Electrical Code,
CSA C22.1 - latest editions.
The vent termination is hot while in
operation and for a period of time following the use of the fireplace. Young
children should be carefully supervised
when they are in the same area as a
hot termination. To prevent contact with
hot surfaces, we recommend the use of
a termination guard. See Page 18 for
ordering information.
These fireplaces are designed as supplemental heaters. Therefore, it is advisable
to have an alternate primary heat source
when installed in a dwelling.
These appliances must not be connected to
a chimney or flue serving a separate solid
fuel burning appliance.

BURNER ADJUSTMENTS
(QUALIFIED TECHNICIANS ONLY)
Flame Appearance and sooting
Proper flame appearance is a flame which is
blue at the base and becomes yellowish-orange
in the body of the flame. When the appliance
is first lit, the entire flame may be blue and will
gradually turn yellowish-orange during the first
15 minutes of operation. After 15 minutes of
operation, if the flame is blue, or if the flame is
orange with evidence of sooting (black tip), the
air shutter opening may need to be adjusted.
If the air shutter opening is closed too far, sooting
may develop. Sooting is indicated by black puffs
developing at the tips of very long orange flames.
Sooting results in black deposits forming on the
logs, appliance inside surfaces and on exterior
surfaces adjacent to the vent termination.
Sooting is caused by incomplete combustion in
the flames and lack of combustion air entering
the air shutter opening. To achieve a warm
yellowish-orange flame with an orange body
that does not soot, the shutter opening must be
adjusted between these two extremes.
Air Shutter Adjustment Guidelines
• Ifthereissmokeorsootpresent,rstcheck
the log set positioning to ensure that the
flames are not impinging on any of the logs.
If the log set is properly positioned and a
sooting condition still exists, then the air
shutter opening should be increased.
• Themoreoffsetsintheventsystem,thelarger
the air shutter opening will need to be.
• Anapplianceoperatedwith theairshutter
opened too far, may have flames that appear
blue and transparent. These weak, blue and
transparent flames are termed anemic.
• Propane models may exhibit ames which
candle or appear stringy. If this is present and
persists, adjust the air shutter to a more open
position, then operate the appliance for a few
more minutes to ensure that the flame normalizes and the flames do not appear sooty.
The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.

Burner Air Shutter Adjustment Procedure
WARNINGS
• Air shutter adjustment should
only be performed by a qualified professional service
technician.
• Ensure front glass panel are
in place and sealed during
adjustment.
Note: See Figure 13 for proper burner flame
appearance.
CAUTION: DO NOT BEND THE AIR SHUTTER
ROD. MAKE SURE THE AIR SHUTTER MOVES
WHEN THE LEVER ARM IS OPERATED.
The adjustment rod and associated adjustable
air shutter is patented technology. Flame adjustments can be made quickly and accurately
to taste without the need of disassembling the
appliance and waiting for 15 minutes after each
adjustment.
Millivolt Appliance Checkout
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" (10 mm) at the pilot generator
(thermopile) and the top 1/8" minimum (tip)
of the quick drop out thermocouple should be
engulfed in the pilot flame. The flame should
project 1" (25 mm) beyond the pilot hood at all
three ports (see Figure 15).
To light the burner, refer to the lighting instructions on Pages 19 and 20.
CAUTIONS
• Soot will be produced if the
air shutter is closed too much.
Any damage due to carboning
resulting from improperly
setting the air shutter is not
covered under the warranty.
• The air shutter door and nearby
appliance surfaces are hot.
Exercise caution to avoid
injury while adjusting flame
appearance.
To adjust the flame, move the lever arm up or
down (located in the lower control area as shown
in Figure 14). When the arm is positioned all
the way down it is fully open. When the arm is
positioned all the way up, it is closed.
Ensure that the air shutter is closed (push lever
all the way up).
To adjust the flame, move the adjustment rod
(located in the lower control area) up or down
to increase or reduce the air shutter opening,
respectively. Position the air shutter to the factory
setting as shown in Figure 14. Allow the burner
to operate for at least 15 minutes. Observe the
flame continuously.
The adjustment rod, arm and associated
adjustable air shutter is patented technology.
Flame adjustments can be made quickly and
accurately to taste without the need of disassembling the appliance and waiting for 30
minutes after each adjustment.
Propane models may exhibit a flame pattern
that may candle or appear stringy. If this is
problematic or persists as the appliance is
continually operated, adjust the air shutter
closed as described in the previous paragraphs.
Operate the appliance for a period of time as the
effect diminishes, ensuring that the appliance
does not develop sooty flames.
Leave the control knob in “ON” position and
turn the remote switch “OFF.” Close the lower
control compartment panel.

TROUBLESHOOTING GUIDE - MILLIVOLT GAS CONTROL SYSTEM
Note: Before troubleshooting the gas control system, Ensure external gas shut off valve, located at gas supply inlet, (and
wall switch, iff applicable), is in the “ON” position.
Important: Valve system troubleshooting should only be accomplished by a qualified service technician.
SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION
1. Spark igniter will not light pilot after
repeated triggering of igniter button.
WARNING: if the pilot will not light
after 1 minute of attempting, wait
for at least 5 minutes for gas to
clear before attempting again.
2. Pilot will not stay lit after
carefully following the lighting
instructions.
3. Pilot burning, no gas to burner, Valve
knob “ON,” and the (standard) burner
OFF/ON switch is “ON." Read important note below.
IMPORTANT NOTE: If an optional
*remote switch is used for burner
operation, if the standard burner
OFF/ON switch is still installed on
appliance it must be in the "OFF"
position.
*Optional remote switch kits - wall
switch, wall thermostat or remote
control.
4. Frequent pilot/burner outage prob-
lem.
A. Defective igniter
(no spark at electrode).
B. Defective or misaligned electrode at pilot
(spark at electrode).
C. Gas supply pressure errant. Check inlet gas pressure. It should be within the limits
D. Pilot orifice plugged. Clean or replace pilot orifice.
A. Defective pilot generator
(thermocouple)
A. Wall switch or wires defective. Check wall switch and wires for proper connections.
B. Thermopile may not be generating suf-
ficient millivolts.
C. Plugged burner orifice. Check burner orifice for blockage and remove.
D. OFF/ON Switch & *Remote Switch are in
the "ON" position resulting in excessive
resistance.
A. Pilot flame may be too low or blowing
(high) causing the pilot/valve safety to drop
out.
Check for spark at electrode and pilot; if no spark
and electrode wire is properly connected, replace
igniter.
Using a match, light pilot. If pilot lights, turn off pilot
and trigger the igniter 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"
to have a strong spark. If gap measures 1/8", replace
pilot (see Figures 15 or 16 on Page 14).
as marked on the rating plate.
Check pilot flame, it must impinge on thermocouple
(see Figures 15 or 16 on Page 14). Clean and/or
adjust pilot for maximum flame impingement on
thermocouple. Ensure that the connection between
the valve and thermocouple are tight and secure.
Jumper wire across terminals at wall switch, if burner
comes on, replace defective wall switch. If okay, jumper
wires across wall switch wires at valve, if burner comes
on, wires are faulty or connections are bad.
Check thermopile with millivolt meter. Take reading
at thermopile terminals of gas valve. Should read
325 millivolts minimum with optional wall switch
“OFF.” Replace faulty thermopile if reading is below
specified minimum.
When turning on the burner using a *remote switch,
ensure that the standard OFF/ON switch is in the "OFF"
position. If both switches are in the ON position, it
may result in excessive resistance (& millivolt drainage) and the burner may not come on.
Clean and/or adjust pilot flame for maximum flame
impingement on thermocouple (see Figures 15 or
16 on Page 14).

TROUBLESHOOTING GUIDE - ELECTRONIC GAS CONTROL SYSTEM
Note: Before troubleshooting the gas control system, Ensure external gas shut off valve, located at gas supply inlet, (and
wall switch, iff applicable), is in the “ON” position.
Important: Valve system troubleshooting should only be accomplished by a qualified service technician.
SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION
1. Nothing happens when ON/OFF switch is
turned on (pilot does not spark).
2. The main burner does not light and the
igniter is sparking.
A. Low voltage/or bad lead wires. Check voltage on AC terminals of module. The value
should be around 24 VAC. Confirm that wire connections are secure.
B. Damaged igniter wire. Check for visible cracked casing, cuts, etc.
C. Damaged pilot assembly. Check pilot assembly for visibly broken spark elec-
trode, etc.
D. On/Off switch defective Check switch and connections. Replace switch, if
necessary.
A. No fuel supply. Ensure that the gas supply is turned on.
B. Loose sensor wire. Ensure sensor wire connection is secure to purple
wire of ignition control.
C. Loose wires to valve. Ensure blue and white (2) wires connection is secure
to valve.
D. Air in the gas line. Purge gas line of air.
E. Low voltage. Test voltage at AC terminals of module for 24 VAC.
If no voltage, replace module.
Check electrical connections between module and gas
control. If okay, replace gas control (valve).
3. The main burner come "ON" but then go
"OFF".
4. The log and glass soot. A. Flame impingement on the log. Check for proper log placement.
A. Gas supply is turned "OFF". Turned gas supply to "ON".
B. Loose wire connection on valve or
ignition module.
C. Flame does not engulf flame sensor. Check location of sensor.
D. Obstructed vent system. Check vent system for obstructions.
B. Improper air shutter opening. Check for proper air shutter openings.
Check wire connection.
