INTRODUCTION

Models DVF32TMHST (with fan) and DVF32TMHST-1
(without fan) are heat circulating gravity direct vent gas
fireplaces with sealed combustion chamber. These fireplaces
use a 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 O.E.M.
mobile home builder or by a qualified service person on-site.
If you are uncertain as to what gas your unit is equipped for,
please check the rating plate located in the interior of the
appliance opening or consult your mobile home supplier or
your local distributor of DESA/Coleman products.

BEFORE BEGINNING THE INSTALLATION OF THE
FIREPLACE, READ THESE INSTRUCTIONS THROUGH,
COMPLETELY.

♦ This DESA/Coleman fireplace and its components

are safe when installed according to this installation
manual. Unless you use DESA/Coleman components,
which has been designed and tested for the fireplace
system, you may cause a fire hazard.

♦ The DESA/Coleman warranty will be voided by and

DESA/Coleman disclaims any responsibility for the
following actions:

-2 - For more information, visit www.desatech.com

a) Modification of the fireplace, components, doors,
blower, fans, air inlet system and damper control.
b) Use of any component part not manufactured or
approved by DESA/Coleman in combination with a
DESA/Coleman fireplace system.

PROPER INSTALLATION is the most important step in
ensuring safe and continuous operation of the fireplace.
Consult the local building codes as to the particular
requirements concerned with the installation of all factory
built fireplaces. This fireplace, when installed, must be
electrically grounded in accordance with local codes, or in
absence of local codes, with the National Electrical Code
ANSI/NFPA 70 and CSA C22.2 Canadian electrical code for
Canada.
The installation must conform to local codes, or in the absence
of local codes, with the national Fuel Gas Code ANSI Z223.1
– current installation code CAN/CGA-B149. This appliance
complies with ANS Z21.88-2000/CSA 2.22-2000 VENTED
GAS FIREPLACE HEATERS.

SELECTING LOCATION

To determine the safest and most efficient location for the
fireplace, you must take into consideration the following
guidelines:

 The location must allow for proper clearances (see

figure 1).

 Consider a location were the fireplace would not be

affected by drafts, air conditioning ducts, windows or
doors.

 A location that avoids the cutting of joists or roof

rafters will make 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 front opening of the appliance or

the flow of combustion and ventilation air. Keep

control compartments accessible.

 Do not locate close to where gasoline or other

flammable liquids may be stored. The appliance area

must be kept clear and free from these combustible

materials.

 Do not use this appliance if any part has been under

water. Immediately contact a local service technician

to examine the fireplace and to replace any part of the

control ignition system and other related components

that has been submerged under water.

MINIMUM CLEARANCES TO COMBUSTIBLES

• Back, side and top spacers ------------------ 0”

• Floor ------------------------------------------ 0”

• Perpendicular wall --------------------------- 2”

• Ceiling to opening --------------------------- 36”

• Sidewall (at nailing flange) ---------------- 0”

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 7).

Figure 7 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 8.

Figure 8

6. 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 8). The vent termination must be
removable for service pipe inspection.

7. For vertical installation, use vertical termination.

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), 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 9).
