FOR YOUR SAFETY

INTRODUCTION

Models CD32M series, CD36M series and CD42M are heat circulating gravity direct vent gas fireplaces with sealed combustion chamber. These fireplaces 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 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, pleas 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:

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

WARNING: Do not block required air space wit insulation or any other material. Do not obstruc effective opening of appliance with any type of facing material.

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 figures 3 and 4. 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.

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).
