INTRODUCTION
-
Models CD32M-B, CD36M-B series and
CD42M-A series are heat circulating gravity
direct vent replaces with sealed combustion
chamber. These replaces use millivolt gas
control valve and millivolt ignition system.
These fireplaces are convertible with the
standard setup as natural gas. Conversion
may be performed by the OEM mobile home
builder or by a qualied service person on-
site. If you are uncertain as to what gas your
unit is equipped for, please check the rating
plate located inside of the appliance opening
or consult your mobile home supplier or your
local distributor of DESA/Vexar products.

BEFORE YOU BEGIN
Before beginning the installation of your
appliance, read these instructions through
completely.
This DESA/Vexar replace and its compo-
nents are safe when installed according to
this installation manual and operated as
recommended. Unless you use DESA/Vexar
components designed and tested for this re-
place system, YOU MAY CAUSE A SAFETY
The DESA/Vexar warranty will be voided by,
and DESA/Vexar disclaims any responsibility
for the following actions:
A) Modication to the replace, components,
doors, blower, fans or vent system.
B) Use of any component part not manu-
factured or approved by DESA/Vexar in
combination with a DESA/Vexar replace
system.
Proper installation is the most important step
in ensuring safe and continuous operation of
the replace. Consult the local building codes
as to the particular requirements concerned
with the installation of all factory built re-
places. This replace, when installed, must be
electrically grounded in accordance with local
codes or in the absence of local codes, with
the National Electrical Code, ANSI/NFPA 70 or
the Canadian Electrical Code, CSA C22.1.
The installation must conform with local codes
or, in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1 or the
Canadian Installation Code, CAN/CGA B149.
This appliance complies with ANSI Z21.88-
1998 and CSA 2.33-M98 as a vented gas
replace heater.
SELECTING LOCATION
To determine the safest and most efcient
location for your replace, consider the fol-
lowing guidelines:
1. The location must allow for proper clear-
ances (see Figure 1).
• Flush installation is recommended where
living space is limited.
• Projected installation may be ideal for
a new addition to an existing nished
wall.
• Corner installation makes use of a space
that may not normally be used and pro-
vides a wider and more efcient range
for radiant heat transfer.

INSTALLATION
2. Consider a location where the replace
would not be affected by drafts, air con-
ditioning 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 precau-
tions must be observed:
• Do not connect this appliance to a chim-
ney system used for solid fuel burning
replace.
• Due to high temperatures, do not locate
this appliance in high trafc areas or near
furniture and draperies.

• Never obstruct the openings of the appli-
ance or ow of ventilation air. Keep the
control compartments accessible.
• Do not locate appliance close to where
gasoline or other ammable 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. Immediately contact a
local service technician to examine the
appliance and to replace any part(s) of the

VENT TERMINATION CLEARANCES
The nal position of your replace depends on
the location of the vent termination in relation
to the clearances that must be observed as
shown in Figure 5 on page 6.
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"
(0.6 cm) for every 12" (30.48 cm) of horizontal
run towards the termination. The maximum
horizontal run depends on the vertical rise
from the replace adapter collar to the vent
termination (see table below).
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. For horizontal installation, an optional
siding standoff may be installed between
the vent cap and the exterior wall. Secure
horizontal vent cap to standoff. Secure
standoff/vent cap assembly to wall (see
Figure 7). Do not seal termination to vent
pipe. The vent termination must be remov-
able for service pipe inspection.
6. For vertical installation, a vertical termi-
nation is available. A vertical ue restrictor
must be installed into inner collar of re-
place as shown in Figure 6, page 7.
When installing a length of pipe for vertical
termination that is over 3 ft., support the
pipe every 3 ft. using metal wall straps.
Vertical to horizontal pipe must be kept at
a 1 ft. to 4 ft. 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 sup-
port the vent pipe every 3 ft. to avoid
excessive stress on the elbows and
possible separation (see Figure 8).

INSTALLATION FOR VERTICAL
TERMINATION
Note
1. Determine the route your vertical venting
will take. If ceiling joists, roof rafters, or
other framing will obstruct the venting
system, consider an offset (see Figure 19)
to avoid cutting load bearing members.
Note: Pay special attention to these instal-
lation instructions for required clearances
(air space) to combustibles when passing
through ceilings, walls, roofs, enclosures,
attic rafters, etc. Do not pack air spaces
with insulation. Also note maximum verti-
cal rise of the venting system and any
maximum horizontal offset limitations.
2. Set the replace in desired location. Drop
a plumb line down from the ceiling to the
position of the replace exit ue. Mark the
center point where the vent will penetrate
the ceiling. Drill a small locating hole at
this point.
Drop a plumb line from the inside of the
roof to the locating hole in the ceiling.
Mark the center point where the vent will
penetrate the roof. Drill a small locating
hole at this point.

DECORATIVE FACING
Any noncombustible material may be used as
facing (glass, tile, brick, etc.) as long as the
proper clearances are observed (see Clear-
ances to Combustibles, page 4). Louvered
openings must not be obstructed and upper
and lower panels must remain accessible for

BURNER FLAME
ADJUSTMENT
The burner ame adjustment (shutter open-
ing) has been factory preset (for natural gas)
to the proper air-to-gas ratio. This ratio results
in an even, clean burning ame across the
burner (see Figure 42).
If adjustment is necessary, you can restore
the proper ame setting by loosening the air
shutter screw and rotating the air shutter until
proper setting is achieved (see Figure 43).
The correct shutter openings are as follows:

OPERATING FIREPLACE
• When used for the rst time, the replace
may emit a slight odor for about 16 to 24
hours. This is normal and is due to the “cur-
ing” of the logs and the “burn-in” of internal
paint and lubricant used in the manufactur-
ing 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 replace
must be replaced prior to operation.
• Have a qualied agency periodically inspect
vent system at the start of each heating
season for any obstruction which will hin-
der its normal operation. Never obstruct
the ow of combustion and ventilation air.
Keep the front of the replace clear of all
obstacles and materials.
