SELECTING LOCATION
To determine the safest and most efficient location for your fire-
place, consider the following guidelines:
1. The location must allow for proper clearances (see Figure 1).
2. Consider a location where the firepace would not be affected
by drafts, air conditioning ducts, windows or doors.
3. A location that avoids the cutting of joists or roof rafters makes
ventilation installation easier.
In selecting a location, the following precautions must be observed:
• Do not connect this appliance to a chimney system used for solid
fuel burning fireplace.
• Due to high temperatures, do not locate this appliance in high
traffic areas or near furniture and draperies.
• Never obstruct the openings of the appliance or flow of ventila-
tion air. Keep the control compartments accessible.
• Do not locate appliance close to where gasoline or other flam-
mable liquids may be stored. The appliance must be kept clear
and free from combustible materials.
• Do not use this appliance if any part has been under water. Imme-
diately contact a local service technician to examine the appli-
ance and to replace any part(s) of the control ignition system and
other related components that have been submerged under water.
Figure 1 - Common Fireplace Locations
Flush installation is recommended where living space is limited.
Projected installation may be ideal for a new addition to an
existing finished wall.
Cornerinstallationmakesuse of a space thatmay not normally be
used and provides a wider and more efficient range for radiant heat
transfer.
CLEARANCES TO COMBUSTIBLES
Minimum clearances to combustibles for the fireplace are:
• Back and Sides of Fireplace.................................................. 0"
• Floor ......................................................................................0"
• Perpendicular Wall ................................................................ 6"
• Front ....................................................................................36"
• Top of Standoffs ....................................................................0"
CAUTION: Do not block required air spaces with
insulation or any other material. Do not obstruct the

VENT TERMINATION CLEARANCES
The final position of your fireplace depends on the location of the
vent termination in relation to the clearances that must be observed
as shown in Figure 5 on page 5.
The vent system serves as the “chimney” as well as the combustion
air supply (air intake). The horizontal run must have a rise of 1/4"
(.6 cm) for every 12" (30.48 cm) of horizontal run towards the
termination. The maximum horizontal run depends on the vertical
rise from the fireplace adapter collar to the vent termination (see
table below).
WARNING: Horizontal sections of this vent sys-
tem require a minimum clearance of 2" from the top
ofthepipeand1"minimum to the sides and bottom.
Vertical sections of this system require a minimum
of1"clearancetocombustiblematerialsonallsides
of the pipe.
VERTICAL HORIZONTAL
0 to 1 ft (30.48 cm)
1 ft (30.48 cm) to 4 ft (121.92 cm)
2 ft (60.96 cm) to 8 ft (243.84 cm)
3 ft (91.44 cm) to 12 ft (365.76 cm)
4 ft (121.92 cm) to 16 ft (487.68 cm)
5 ft (152.40 cm) to 15 ft (457.20 cm)
6 ft (182.88 cm) to 14 ft (426.72 cm)
7 ft (213.36 cm) to 13 ft (396.24 cm)
8 ft (243.84 cm) to 12 ft (365.76 cm)
WARNING: Never allowtheventtorun downward

FRAMING
Once the final location has been determined, observing height clear-
ances for vent termination, you may construct framing using dimen-
sions shown in Figures 3 and 4, depending on your installation.
If the appliance is to be installed directly on carpeting, tile (other
than ceramic), or any combustible material other than wood floor-
ing, the appliance must be installed on a metal or wood panel
extending the full width and depth of the appliance.

GAS LINE HOOK-UP
WARNING: Gas line hook-up should be done by
your gas supplier or a qualified service person.
WARNING: Before you proceed, make sure your
gas supply is OFF.
Anequipment shutoff valve has beenincluded inthe fireplace's gas
supply system. However, consider installing an extra shutoff valve
outside the appliance’s enclosure (check local codes), where it can
be accessed more conveniently with a key through a wall as shown
in Figure 12.
Inconformance withlocal codes, routea 1/2"NPT gasline towards
the appliance coming in from either the left or right side of the
fireplace (see Figure 13).
Install a sediment trap between the incoming gas line and the gas
controlbox.(seeFigure14).Thesedimenttrapshould extend down
a minimum of 3" (7.62 cm) beyond the center of the pipe.
When routing gas line through conduit sleeve, make sure to repack
insulation to fill gaps between gas line and conduit sleeve. Com-
poundsusedon threaded jointsofgas piping shallberesistant to the
action of propane or natural gas. Compounds should be applied
lightly to ensure excess sealant does not enter the gas line.
WARNING: All gas piping and connections must
betestedfor leaks aftertheinstallationiscompleted.
Never use an open flame to check for a leak. After
ensuring that the gasvalve is open apply commercial
leak detection fluid to all gas joints. Bubbles forming
show a leak. Correct all leaks at once.
Do not operate any appliance if a leak is detected.

Lava Rock and Ember Material
1. For all models, place lava rock along sides and front of firebox
bottom in areas that are visible. It is not necessary to use all
lava rock provided.
NOTICE: Do not put lava rock on or under burner.
Placing lava rock on burner could cause perfor-
mance problems.
2. Pull embermaterial apartintopieces nolargerthana dime.Place
loosely and directly onto exposed section of front burner and
along space between burner and grate prongs. These will create
glowing ember appearance as flame touches ember material.
Do not block air slots by using too much ember material in one
area. It is not necessary to use all ember material provided.
3. When lava rock and ember material are in place, close and
latch glass door and secure louvers in place.
WARNING: The glass door must be securely in
place before operating fireplace. Do not operate fire-
place if glass is missing or broken.
DECORATIVE FACING
Any noncombustible material may be used as facing (glass, tile,
brick, etc.) as long as the proper clearances are observed (see
Clearances to Combustibles, 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.
FACE EXTENSION FOR MODEL CD32M ONLY
Model CD32M comes equipped with a front face extension. The
front face extension would add 3 1/2" to the width and 3/4" to the
height of the fireplace face.
To install face extension:
1. Remove existing screws from front face assembly as shown in
Figure 29.
2. Align holes on top face extension with holes on top side of
frontface assembly andsecure withscrews previously removed

OPERATION GUIDELINES
• When used 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 lu-
bricant used in the manufacturing process.
• Keep compartments, logs, burners and area surrounding logs
clean by vacuuming and brushing at least twice a year or as
necessary.
• Turn off gas and remote 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 vent system at the
startof each heating seasonfor any obstruction which will hinder
its normal operation. Never obstruct the flow of combustion and
ventilation air. Keep the front of the fireplace clear of all ob-
stacles and materials
