Desa WCM-42J Fireplace Installation, Selecting location, Minimum clearance to combustibles

Fireplace Installation

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 clear- ances (see Figures 4 and 5).

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

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

4.An outside air kit is available with this fireplace (see Optional Outside Air Kit on page 8).

Minimum clearance to combustibles

Back and sides of fireplace		1 1/2" min.*
Front of fireplace		48" min.
Floor**		0" min.
Perpendicular wall to opening		18" min.
36" Models		12" min.
Top spacers		0" min.
Mantel clearances	see Mantels, page 7
Chimney outer pipe surface		2" min.
36" Model		1" min.

*Not required at nailing flanges ** See step 2 of Framing

Framing

1.Frame opening for fireplace using dimen- sions shown in Figures 4 and 5.

2.If fireplace is to be installed directly on carpeting, tile (other than ceramic) or any combustible material other than wood flooring, fireplace must be installed upon a metal or wood panel extending full width and depth of fireplace.

3.Set fireplace directly in front of this open- ing and slide unit back until nailing flanges touch side framing.

4.Check level of the fireplace and shim with sheet metal if necessary.

5.Before securing fireplace to prepared framing, ember protector (provided) must be placed between hearth extension (not supplied) and under bottom front edge of fireplace to protect against glowing embers falling through. If fireplace is to be installed on a raised platform, a Z-type ember pro- tector (not supplied) must be fabricated to fit your required platform height. Ember protector should extend under fireplace a

minimum of 1 1/2". Ember protector should be made of galvanized sheet metal (28 gauge minimum to prevent corrosion.

6.Using screws or nails, secure fireplace to framing through flanges located on sides of fireplace.

WARNING: Do not pack re- quired air spaces with insulation or other materials.

Minimum/Maximum Chimney Height for Residential Installation

Minimum height of chimney, measured from base of fireplace to flue gas outlet of termina- tion, is 16 feet for straight flue or a flue with one elbow set. Maximum distance between elbows is 6 feet. For systems with two elbow
