INTRODUCTION
The Fireplace models covered in this manual
are Direct-Vent sealed combustion gas fireplace heaters designed for residential application. 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, vent system.

The millivolt appliances are designed to operate on either natural or propane gas. A millivolt
gas control valve with piezo ignition system
provides safe, efficient operation. If any optional accessories which require electrical
power are being installed, the electrical power
must be provided at the time of appliance
installation.
The electronic appliances are designed to operate on either natural or propane gas. An
electronic intermittent pilot system provides
safe, efficient operation. External electrical
power is required to operate these units.

2. When lit for the first time, this appliance will
emit a slight odor for 14 hours. This is due to the
“burn-in” of internal paints and lubricants used in
the manufacturing process.

6. Remember, Millivolt appliances have a continuous burning pilot flame. Exercise caution
when using products with combustible vapors.

Glass Cleaning
It will be necessary to clean the glass periodically. During start-up it is normal for condensation to form on the inside of the glass. This
can cause lint, dust and other airborne particles to cling to the glass surface. Also initial
paint curing may deposit a slight film on the
glass. It is therefore recommended that the
glass be cleaned two or three times with a nonammonia household cleaner and warm water (a
gas fireplace glass cleaner is recommended).
After that the glass should be cleaned two or
three times during each heating season, depending on the circumstances present.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service technician. However, more frequent periodic inspections and cleanings should be performed by
the homeowner. Homeowner must contact a
qualified service technician at once if any
abnormal condition is observed.
Refer to the maintenance schedule for maintenance tasks, procedures, periodicity and by whom
they should be performed. Always verify proper
operation of the appliance after servicing.
IMPORTANT: TURN OFF GAS AND ANY
ELECTRICAL POWER BEFORE SERVICING
THE APPLIANCE.

The following paragraphs address burner adjustment concerns and procedures.
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 will
exhibit flames that are blue and transparent.
These weak, blue and transparent flames are
termed anemic. If the air shutter opening is too
small 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.

Firebox Floor
Glass Door Latch

CDST Shown

To install the front glass enclosure panel,
proceed as follows:
1. Visually inspect the gasket on the backside
of the panel. The gasket surface must be clean,
free of irregularities and seated firmly.
2. Position the glass enclosure panel in front of
the firebox opening at a 45 degree angle and
engage the top flange over the lip at the top of
the firebox opening.
3. Swing the glass enclosure panel down and
back. Ensure the gasket seats evenly as the
panel draws shut. Engage the Vee-flange at the
bottom of the panel with the latches and close
the latches to secure the panel.

If the log set is properly positioned and
sooting conditions exist, the air shutter opening on the main burner tube should be adjusted. Normally, the more offsets in the vent
system, the greater the need for the air shutter
to be opened further.

ENSURE THAT ALL GLASS PANELS ARE IN
PLACE AND SEALED DURING ADJUSTMENT.
Adjustment
CAUTION: THE ADJUSTMENT ROD AND
NEARBY APPLIANCE SURFACES ARE HOT.
EXERCISE CAUTION TO AVOID INJURY WHILE
ADJUSTING FLAME APPEARANCE.
To adjust the flame, rotate the adjustment
rod (located in the lower control area) counterclockwise to increase or clockwise to reduce the air shutter opening. Adjust the air
shutter to the recommended setting as
shown in Figure 5. Allow the burner to operate for at least 15 minutes. Observe the flame
continuously. If it appears weak or sooty as
previously described, adjust the air shutter
by rotating the adjustment rod until the flame
appearance is as desired.

4. Reinstall the top louver assembly or radiant
panel.

Note - Burners are omitted in this view for clarity.

Sooting is caused by incomplete combustion 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. Reposition the log set
if the flames impinge on any part of it.

WARNING: AIR SHUTTER ADJUSTMENT SHOULD ONLY BE PERFORMED
BY A QUALIFIED PROFESSIONAL SERVICE TECHNICIAN.

COOL. TURN OFF ALL GAS TO THE
APPLIANCE BEFORE INSTALLING THE
GRATE AND LOG SET.
WARNING: THIS APPLIANCE IS NOT
DESIGNED TO BURN WOOD. ANY ATTEMPT TO DO SO COULD CAUSE IRREPARABLE DAMAGE TO YOUR APPLIANCE AND PROVE HAZARDOUS TO
YOUR SAFETY.
WARNING: THE SIZE AND POSITION
OF THE LOG SET WAS ENGINEERED TO
GIVE YOUR APPLIANCE A SAFE, RELIABLE AND ATTRACTIVE FLAME PATTERN. ANY ATTEMPT TO USE A DIFFERENT LOG SET IN THE FIREPLACE
WILL VOID THE WARRANTY AND WILL
RESULT IN INCOMPLETE COMBUSTION, SOOTING, AND POOR FLAME
QUALITY.
The log set, the decorative volcanic stone
and the glowing embers (rockwool) are located inside the unit. Refer to the following
information and Figures 6 and 7 for detailed
placement instructions for the logs, the decorative volcanic stone and the glowing embers. Figure 6 also shows a typical flame
pattern for this particular appliance.
Install the unitized log set:
a - The bottom of the log set is notched to
accommodate the pilot.
b - Place the log set so that the four inner
notches on the underside of the log set fit over
the four risers located on the burner ends. See
Figure 6. This procedure is accomplished primarily by feel, as the log set masks the burner
risers as it is being installed.
c - As a final check for correct log set placement, check that the four outer notches on the
underside of the log set fit over the burner
tines as indicated in Figure 6.

gap between the bottom of the horizontal grate
section and the top of the pile of decorative
volcanic stone. Place a few dime-sized pieces
of the glowing ember material on the pan
burner in front of the burned out area on both
sides of the log set. The glowing embers may
touch one another, but should not overlap
each other.

Note: The burners are not identical. Position them so
that the circular burner ports run as shown. Note
especially the vertical run of ports relative to the pilot
burner. Bracket A on the rear burner will interfere
with the pilot burner if an attempt is made to install
the rear burner in the front burner’s position.

TROUBLESHOOTING THE MILLIVOLT GAS CONTROL SYSTEM
Note: Before troubleshooting, make sure that the appliance main line gas shut-off valve and the gas control valve are in the "OPEN"

position and the burner ON/OFF switch is in the “ON” position.

Important: Valve system troubleshooting should only be accomplished by a qualified service technician.

SYMPTOM

CORRECTIVE ACTION

A. Defective ignitor
(no spark at electrode).

Check for spark at electrode and pilot; if no spark and
electrode wire is properly connected, replace ignitor.

B. Defective or misaligned electrode
at pilot (spark at electrode).

Using a match, light pilot. If pilot lights, turn off pilot and
trigger the ignitor 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 (Figure 9 on page 7).

C. Gas supply pressure errant.

Check inlet gas pressure. It should be within the limits as
marked on the rating plate.

D. Pilot orifice plugged.

Clean or replace pilot orifice.

2. Pilot will not stay lit after
carefully following the
lighting instructions.

A. Defective pilot generator
(thermocouple).

Check pilot flame, it must impinge on thermocouple (Figure
9 on page 7) Clean and/or adjust pilot for maximum flame
impingement on thermocouple. Ensure that the connection
between the valve and thermocouple are tight and secure.

3. Pilot burning, no gas to
burner, Valve knob “ON,”
Wall Switch “ON.”

A. Wall switch or wires defective.

Check wall switch and wires for proper connections. 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.

B. Thermopile may not be generating
sufficient millivoltage.

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.

C. Plugged burner orifice.

Check burner orifice for stoppage and remove.

A. Pilot flame may be too low or
blowing (high) causing the pilot/
valve safety to drop out.

Clean and/or adjust pilot flame for maximum flame impingement on thermocouple (Figure 9 on page 7).

1. Spark ignitor will not light
pilot after repeated
triggering of ignitor button.

4. Frequent pilot/burner outage
problem.

TROUBLESHOOTING THE ELECTRONIC IGNITION SYSTEM
Note: Before troubleshooting, make sure that the appliance main line gas shut-off valve and the gas control valve are in the "OPEN"

position and the burner ON/OFF switch is in the “ON” position.
Important: Valve system troubleshooting should only be accomplished by a qualified service technician.

SYMPTOM

POSSIBLE CAUSES

1. Burner will not light.

CORRECTIVE ACTION

A. Faulty Valve System.

See Below.

B. “OFF/ON” or wall switch
defective.

Disconnect the two black wires from the wire nuts. Test switch(s) for
continuity with a multimeter. If continuity is not indicated, switch(s) is
defective and must be replaced.

Note: Before replacing “OFF/ON” switch, be sure to check wiring for loose
connections or broken wires and repair as needed.
2. Burners come “ON” but
go “OFF.”

A. Burner orifice plugged.

Check main burner orifice(s) for stoppage. Clean or replace.

B. Obstructed vent system.

Check vent system for obstructions.
