CHECK HUD REQUIREMENTS BEFORE INSTALLING THIS FIREPLACE.

FOR YOUR SAFETY

INTRODUCTION

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

♦ This DESA fireplace and its components are safe

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

♦ The DESA warranty will be voided by and DESA

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 in combination with a DESA 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. Although grounding may not be required by code the manufacturer recommends it.

This Model fireplace C36EMW meets the construction and safety standards of HUD for application in mobile homes when installed according to these instructions.

WARNING: Do not install a fireplace insert in this box unless the manufacturers instructions with the insert specificall tested for use with the insert.

This fireplace is not intended to be used as a substitute for a furnace to heat an entire home. Use for supplemental heat only.

FIRELOGS ONLY.

WARNING: When processed wood fuel fire logs

are used, do not poke or stir the logs while they are

urning. Use only fire logs that have been evaluated fo the application in fireplace and refer to fire log warnings and caution markings on packaging prior to use.

This wood burning fireplace complies with UL 127 standard as a FACTORY BUILT FIREPLACE.

CAUTION: The structural integrity of the mobile home floor, and ceiling/roof must be maintained.

SELECTING LOCATION

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

1.) The location must allow for proper clearances (see figures 1 & 2).

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

3.) A location that avoids the cutting of joists or roof rafters will make installation easier.

4.) An outside air kit is included with this fireplace. For more details refer to section on outside air kit installation on page 4.

MINIMUM CLEARANCES TO COMBUSTIBLES

• Back and side of fireplace -------------- ¾” minimum Note: The ¾” clearance is not required at the nailing flanges

• Floor* ------------------------------------- 0” minimum *See step 2 of “Installing the Fireplace” on page 3

• Perpendicular Wall to Opening of unit - 12” minimum

• Top Spacers ------------------------------ 0” minimum

• Mantel Clearances -------------- see page 8 “Mantels”

• Chimney Outer Pipe Surfaces --------- 1” minimum

insulation or other materials.

MINIMUM / MAXIMUM CHIMNEY HEIGHT

The minimum height of the chimney, measured from the base of the fireplace to the flue gas outlet of the termination, is 11.5 feet for straight flue or a flue with one elbow set. The maximum distance between elbows is 2 feet. For systems with 2 elbow sets, minimum height is 22 feet. The maximum height of any system is 28 feet. This measurement includes the fireplace, chimney sections and the height of the termination assembly at the level of the flue gas outlet (see page 6, figure 15).

FRAMING AND INSTALLING THE FIREPLACE

STEP 1: Frame the opening for the fireplace using the dimensions shown in figures 1 & 2. STEP 2: If the fireplace is to be installed directly on carpeting, tile (other than ceramic), or any combustible material other than wood flooring, the fireplace must be installed upon a metal or wood panel extending the full width and depth of the fireplace.

WARNING: Do not install in a bedroom.

WARNING: Do not pack required air spaces with

STEP 3: Set the fireplace directly in front of this opening and

slide the unit back until the nailing flanges touch the side framing. STEP 4: Check the level of the fireplace and shim with sheet metal if necessary. Make sure the unit is balanced on each side.

Figure 2 CORNER INSTALLATION

Figure 3 TIE-DOWN STRAP

STEP 5: Before securing fireplace to prepared framing, the ember protector (provided), must be placed between the hearth extension (not supplied), and under the bottom front edge of the fireplace to protect against glowing embers falling through. If the fireplace is to be installed on a raised platform, a Z-type ember protector (not supplied) must be fabricated to fit your required platform height. The ember protector should extend under the fireplace a minimum of 1 - 1/2”. The ember protector should be made of galvanized sheet metal (28-gage minimum). STEP 6: Secure the fireplace to the floor using tie-down straps (see figure 3) to prevent shifting.

HEARTH EXTENSION

A hearth extension projecting a minimum of 16” in front of and a minimum of 8” beyond each side of the fireplace opening is required to protect combustible floor construction in front of the fireplace. Fabricate a hearth extension using a material which meets the following specifications: a layer of non-combustible, inorganic material having a thermal conductivity of K = 0.84 BTU IN/FT. HR. F (or less) at 1” thick. For example, if the material selected has a K factor of

0.25, such as glass fiber, the following formula would apply:

0.25 x 1.0” = 0.30 thickness required

0.84

Thermal conductivity “K” of materials can be obtained from the manufacturer or supplier of the non-combustible material. If the hearth extension is to be covered, use non-combustible material such as tile, slate, brick, concrete, metal, glass, marble, stone etc. Provide a means to prevent the hearth extension from shifting and seal gap between the fireplace frame and hearth extension with a non-combustible material (see figure 4).

Figure 4 HEARTH EXTENSION

WARNING: Hearth extension is to be installed onl

as illustrated.

OUTSIDE AIR KIT (MODEL AK-6)

The installation of an outside air kit should be performed during the rough framing of the fireplace due to the nature of its location. Outside combustion air is accessed through the mobile home floor (Refer to AK-6 Installation Instructions for details). In some instances, a wall installation is required (see Figure 5). Note: An AK-6WAI Air Kit must be ordered when a sidewall installation is required (see accessories on page 12). See page 10, figure 25 for instructions on how to operate the air kit.

Figure 5 OUTSIDE AIR KIT

FAN KIT ASSEMBLY (BK3)

A fan kit assembly is preinstalled in this fireplace. Use of blowers or fans other than manufactured by DESA voids the warranty. The fan is operated by pressing the rocker switch located at the lower right hand corner of the fireplace face. Fan kit electrical connections are made through the electrical cover plate located on the side of the fireplace as shown in figure 6a.

Figure 6a FAN SWITCH AND STRAIN RELIEF

FAN KIT WIRING INSTRUCTIONS

i. Loosen the strain relief by turning the plastic screw

counterclockwise.

ii. Remove electrical cover plate (with strain relief)

from the fireplace by removing the two sheet metal screws as shown in figure 6a.

iii. Slide power source wiring through the strain relief

opening and electrical cover plate and make all the necessary connections.

iv. Slide all wiring connections in the electrical housing

as shown in figure 6b.

v. Secure the electrical cover plate with screws

previously removed.

vi. Tighten strain relief plastic screw. NOTE: Electrical housing and cover plate have sharp edges, wear protective gloves.

CHIMNEY PIPE

The DESA chimney system consists of 12, 18, 24, 36 and 48 inch, snap-lock double-wall pipe segments, planned for maximum adaptability to individual site requirements. Actual lengths gained after fitting overlaps must be taken into consideration (lineal gain) and are given in the lineal gain chart (see figure 7). There are two vent kits available, which have been specially designed for common installations in manufactured (mobile homes): MW8K (8’ Vent Kit) and MW9K (9’ Vent Kit). The contents of these kits are listed under accessories on page 12. Most chimney systems for manufactured houses require a standard straight installation as described in this section. If an uncommon offset installation is required, see page 10.

Figure 7 LINEAL GAIN

Important: If the height of the chimney assembly exceeds requirements for transportation of the home, the chimney installation may be completed after the home is sited. Note: the termination must always be installed after the home is sited.
