VENT INSTALLATION INSTRUCTIONS
1. Install pipe to fireplace collar adapter located on back
of unit at a 45 deg. Angle. Connect our starting pipe
to a 45 deg. Starting section by sliding it over the
collar adapter on the fireplace. Twist-lock for proper
installation check to insure proper connection (see
figure 5).
Figure 5 VENT INSTALLATION
2. Once the elbow is properly fastened to the fireplace
adapter, continue to install the remainder of the pipe
for the desired installation.
3. Install every section of the pipe making sure that all
joints are properly twist-locked.
4. After steps 1, 2 and 3 are completed, install the vent
termination. Depending on location of termination,
you may use a vertical or horizontal termination.
5. Depending on the wall thickness, allow one inch to
protrude from internal wall as shown in figure 6.
6. For vertical venting application, install vertical flue
restrictor into inner collar of fireplace as shown in
figure 5.
Figure 6 VENT TERMINATION
7. An optional siding standoff may be installed between
the vent cap exterior wall. Secure horizontal top to
standoff and then secure the complete assembly to
wall (see figure 6). The vent termination must be
removable for service pipe inspection.
The vent system serves as the “chimney” as well as the
combustion air supply (air intake). The horizontal run must
have a rise of ¼” (6 mm) for every 1 foot (305 mm) of
horizontal run towards the termination. Never allow the vent
to run downward. The maximum horizontal run depends on
the vertical rise from fireplace adapter collar to the vent
termination (see table below).

WARNING: Vent pipe air space clearances to
combustibles are 1” on all sides except on the horizontal
sections, which require 2” clearances from the top of the
pipe. Where the termination cap penetrates a combustible
wall, 1” air space clearance is required.
When installing length of pipe over 3 ft. (914 mm)
horizontally, support the pipe every 3 ft. (914 mm) using
metal straps. Vertical to horizontal pipe must be kept at a one
foot (305 mm) to 4 ft. (1219 mm) ratio with a maximum run
of no more than 20 ft.
If an offset is necessary in the attic to avoid obstruction, it is
important to support the vent pipe every 3 ft. (914 mm), to
avoid excessive stress on the elbows and possible separation
see figure 7).

GAS SUPPLY TESTING
NOTE: This section is intended as a guide for qualified
technicians installing gas to the appliance.
WARNING: Do not connect appliance before pressure
testing gas piping. Damage to gas valve may result and a
unsafe condition may be created.
The appliance and its individual shut-off valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of ½
psig (3.5 kPa).
The appliance must be isolated from the gas supply piping
system by closing its individual manual shut-off valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than ½ psig (3.5 kPa).
The gas control valve is secured underneath the firebox. Two
1/8 NPT plugged tappings are provided on the gas control
valve for pressure test gauge connections (see figure 12).
GAS LINE HOOK-UP
Gas line hook-up should be done by your gas supplier or
licensed service technician.
NOTE: Before you proceed, make sure your gas supply is off.
A manual shut-off valve has been included in the fireplace’s
gas supply system. However, consider installing an extra
shut-off valve outside the appliance’s enclosure (check with
local codes), where it can be accessed more conveniently with
a key through a wall as shown in figure 13.
In conformance with local codes, route a ½” NPT gas line
towards the appliance coming in from either the left or right
side of the fireplace (see figure 14).
CAUTION: Do not kink flexible gas line.

Install a sediment trap between the incoming gas line and the
d
n
N
gas control box (see figure 15). The sediment trap should
extend down a minimum of 3 inches (76 mm) beyond the
center of the pipe.
Figure 15 SEDIMENT TRAP
When routing gas line through conduit sleeve, make sure to
repack insulation to fill gaps between gas line and conduit
sleeve. Compounds used on threaded joints of gas piping shall
be resistant to the action of propane or natural gas.
Compounds should be applied lightly to ensure excess sealant
does not enter the gas line.
Complete your gas line installation by connecting the
incoming gas line to flexible gas line. Secure tightly with a
wrench but do not over-tighten.
CAUTION: All gas piping and connections must be teste
for leaks after the installation is completed. After ensuring
that the gas valve is on, apply a commercial leak detectio
solution to all connections and joints. Bubbles forming
show a leak. Correct all leaks at once. DO NOT USE AN
OPEN FLAME FOR LEAK TESTING AND DO NOT
OPERATE ANY APPLIA
DETECTED. LEAK TESTING SHOULD BE DONE BY
A QUALIFIED SERVICE PERSON.
PILOT ADJUSTMENT
The pilot or electrode assembly is factory preset for the proper
flame height. Alterations to these settings may have occurred
during shipping and handling. If this is the case, some minor
readjustments may be necessary and should be done by a
qualified service technician. The proper settings for the
thermopile height should be at a distance of 3/8” (10mm) to
½” (13mm) from the pilot flame as shown in figure 16.

LOG INSTALLATION
Each log is marked with a number in the following diagrams.
These numbers will help in identifying the logs when
installed. It is very important to install these logs exactly as
instructed. Do not modify logs and only use logs supplied
with fireplace.
FOR MODELS CD32M AND CD36M SERIES
• Place log #1 (back log) on top of grate. Make sure
the notches in the bottom of the log fit over the grate.
• Rest log #2 (large front log) on the pins on the front
part of the grate.
• Place log #3 (C-shaped crossover log) onto the rear
and front logs. Make sure it is seated properly on the
smooth surface on the front log and on the pin on the
back log as shown below.
• Place log #4 (small, round log) on the pin on the right
side of front log as shown below.
• Place log #5 (small log) onto the front left part of the
grate making sure the notches fits over the prongs of
the grate.
• Place log #6 onto two pins on the left side of back
and front log.
• Place lava rock along sides and front of firebox
bottom in areas that are visible. It is not necessary to
use all of the lava rock provided.
FOR MODEL CD42M
• Place log #1 (base log) onto pin on left side of grate.
• Rest left side of log #2 (front log) onto top of log #1.
Place right side of log onto second pin located on the
right side of the grate.
Place log #3 (rear log) onto pins on rear of grate.
• Place log #4 (crossover log) onto pins from both logs
#2 and #3.
• Place log #5 (top log) onto right pin of front log (#2)
and the smooth surface of rear log (#3). Make sure it
is seated properly.

• Place log #6 (left log) onto left pin of front log (#2)
r
p
and the smooth surface of rear log (#3). Make sure it
is seated properly.
• Place log #7 onto right pin of top log (#5). Make sure
it is seated properly.
WARNING: Improper installation, adjustment,
alteration, service or maintenance can cause injury o
roperty damage. Refer to this manual for assistance.
Consult a qualified installer for additional information.
NOTICE: Do not put lava rock on or under the burner.
Placing lava rock on burner could cause performance
problems.
• Pull ember material apart into pieces no larger than a
dime. Place these pieces loosely and directly onto
the exposed section of the front burner and along the
space between the burner and grate prongs. These
will create the glowing ember appearance as the
flame touches the ember material. Do not block air
slots by using too much ember material in one area.
It is not necessary to use all of the ember material
provided.
• Close glass door, lock door latches and secure
louvers in place.
WARNING: The glass door must be securely in place
before operating the fireplace. Do not operate the fireplace
if glass is missing or broken.
BURNER FLAME ADJUSTMENT
The burner flame adjustment (shutter opening) is factory
preset (for natural gas) to the proper air-to-gas ratio. This ratio
results in an even and clean burning flame across the burner
(see figure 19).
Figure 20 AIR SHUTTER ADJUSTMENTS
DECORATIVE FACING
Any non-combustible material may be used as facing (glass,
tile, brick etc.) as long as the proper clearances are observed
(refer to section on clearances on page 3). Louvered openings
must not be obstructed and upper and lower panels must
remain accessible for service. Use only heat-resistant, noncombustible mortar or adhesive when securing decorative
facing materials.
OPERATING GUIDELINES
When lit for the first time, the fireplace may emit a slight odor
for about 16 to 24 hours. This is normal and is due to the
“curing” of the logs and the “burn-in” of internal paint and
lubricant used in the manufacturing process.
Keep compartments, logs, burners and area surrounding the
logs clean by vacuuming and brushing at least twice a year or
as necessary.
Turn off gas and remote wall switch before servicing
appliance. Any safety screen or guard removed for servicing
the fireplace must be replaced prior to operation. Have a
qualified agency periodically inspect the vent system at the
start of each heating season for any obstruction, which hinder
its normal operation. Never obstruct the flow of combustion
and ventilation air. Keep the front of the fireplace clear of all
obstacles and materials.
Figure 19 BURNER FLAME
If adjustment is necessary, you can restore the proper flame
setting by loosening the air shutter screw and rotating the air
shutter until proper setting is achieved (see figure 20). The
correct shutter opening is listed below.

blowing (high) causing the valve
safety to drop out.
• Check pilot flame. It must
impinge on thermocouple.
• Clean or adjust pilot for
maximum flame impingement on
thermocouple.
• Ensure that the connection
between the valve and
thermocouple are tight and
secured.
• Check remote wires for proper
connections. Jumper wire across
terminals at remote control, if
burner comes on, replace
defective remote. If okay, jumper
wire across remote control 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 remote control off.
Replace thermopile if reading is
below specified minimum.
• Check burner orifice for stoppage
and remove.
• Check thermocouple with
millivolt meter. Take reading at
thermocouple terminals of gas
valve. Should read 18 millivolts
minimum with remote control off.
Replace faulty thermocouple if
reading is below specified
minimum.
• Clean and/or adjust pilot flame
for maximum flame impingement
on thermocouple.
