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).

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.
