INTRODUCTION

WARNING:Thisproductcontainsand/orgenerateschemicals known to the State of California to cause cancer or birth defects or other reproductive harm.

Models CD32M series, CD36M-A series and CD42M-A series are heat circulating gravity direct-vent fireplaces with sealed combustion chamber.Thesefireplacesusemillivoltgascontrol valve and millivolt ignition system.

These fireplaces are convertible with the standard setupasnaturalgas.Conversionmaybeperformed 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 inside of the appliance opening or consult your mobile home supplier or your local distributor of DESA/Vexar products.

NOTICE: Check local building codesforarearequirementsbefore installing this appliance.

BEFORE YOU BEGIN

Before beginning the installation of your appliance, read these instructions through completely.

ThisDESA/Vexarfireplaceanditscomponentsare safe when installed according to this installation manual and operated as recommended. Unless you use DESA/Vexar components designed and tested for this fireplace system, YOU MAY CAUSE

A SAFETY HAZARD!

The DESA/Vexar warranty will be voided by, and DESA/Vexar disclaims any responsibility for the following actions:

A)Modification to the fireplace, components, doors, blower, fans or vent system.

B)Useofanycomponentpartnotmanufacturedor approved by DESA/Vexar in combination with a DESA/Vexar fireplace system.

Proper installation is the most important step in ensuring safe and continuous operation of the fireplace.Consultthelocalbuildingcodesastothe 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 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, intheabsenceoflocalcodes,withtheNationalFuel 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 FIREPLACE HEATER.

SELECTING LOCATION

To determine the safest and most efficient location for your fireplace, consider the following guidelines:

1.The location must allow for proper clearances (see Figure 1).

2.Consider a location where the fireplace would not be affected by drafts, air conditioning ducts, windows or doors.

3.Alocationthatavoidsthecuttingofjoistsorroof 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 ventilation air. Keep the control compartments accessible.

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 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" (.6 cm) for every12"(30.48cm)ofhorizontalruntowardsthe termination.Themaximumhorizontalrundepends ontheverticalrisefromthefireplaceadaptercollar to the vent termination (see table below).

WARNING: Never allow the vent to run downward as this may cause excessive temperatures which could cause a fire.

WARNING: Horizontal sectionsofthisventsystemrequire a minimum clearance of 2" from the top of the pipe and 1" minimum to the sides and bottom. Vertical sections of this system require a minimum of 1" clearance to combustible materials on all sides of the pipe.

FRAMING

Once the final location has been determined, observing height clearances for vent termination, you may construct framing using dimensions shown in Figures 3 and 4, depending on your installation.

INSTALLATION

WARNING: Read all instructionscompletelyandthoroughly before attempting installation. Failure to do so could result in serious injury, property damage or loss of life. Operation of improperly installed and maintained venting system could resultinseriousinjury,property damage or loss of life.

NOTICE:Failuretofollowtheseinstructions will void the warranty.

VENTING INSTALLATION PRECAUTIONS

Consult local building codes before beginning the installation. The installer must make sure to select the proper vent system for installation. Before installing vent kit, the installer must read this fireplace manual and vent kit instructions.

Only a qualified service person should install venting system. The installer must follow these safety rules:

Wear gloves and safety glasses for protection

Use extreme caution when using ladders or when on roof tops

Be aware of electrical wiring locations in walls and ceilings

The following actions will void the warranty on your venting system:

Installation of any damaged venting component

Unauthorized modification of the venting system

Installation of any component part not manufactured or approved by DESA

Installation other than as instructed by these instructions

WARNING:Thisgasfireplace and vent assembly must be venteddirectlytotheoutside.The venting system must NEVER be attached to a chimney serving a separatesolidfuelburningappliance. Each gas appliance must use a separate vent system. Do not use common vent systems.

WARNING: Horizontal sectionsofthisventsystemrequire a minimum clearance of 2" from the top of the pipe and 1" minimum to the sides and bottom. Vertical sections of this system require a minimum of 1" clearance to combustible materials on all sides of the pipe.

VENTING INSTALLATION

1.Installelbowtofireplacecollaradapterlocated on back of the unit at a 45° angle. Slide elbow over collar and twist to lock. Check to insure proper connection (see Figure 6).

2.Continue to install remainder of pipe for desired installation. Make sure each section is twist-locked securely.

3.When installation of vent pipe is complete, in stall vent termination. Depending on the location of your fireplace, you will vent vertically or horizontally.

4.Allow 1" of pipe to protrude from internal wall, depending on wall thickness. See Figure 7, page 8.

5.For horizontal installation, an optional siding standoff may be installed between the vent cap andtheexteriorwall.Securehorizontalventcap to standoff. Secure standoff/vent cap assembly towall(seeFigure7,page8).Donotsealtermination to vent pipe. The vent termination must be removable for service pipe inspection.
