Desa (V)gM42 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 clearances (see Figures 1 and 2).

2.Consider a location where the fireplace will 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 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.
Model GM36	12" min.
Top spacers	0" min.
Mantel clearance	see Mantels, page 7
Chimney outer pipe surface	2" min.
Models GM36	1" min.

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

Framing

1.Frame the opening for the fireplace using the dimensions shown in Figures 1 and 2.

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

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

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

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 fire- place 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 gauge minimum to prevent corrosion.

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

WARNING: Do not pack re- quired air spaces with 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 16 feet for straight flue or a flue with one elbow set. The maximum distance between elbows is 6 feet. For systems with two elbow sets, the minimum height is 22 feet. The maximum height of any system is 50 feet. This
