FRAMING

1. Frame opening for fireplace using dimensions shown in Figures

6 and 7.

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 opening and slide unit back

until nailing flanges touch side framing.

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

5. Before securing firebox to prepared framing, ember protector

(provided) must be placed between hearth extension (not sup-

plied) and under bottom front edge of firebox to protect against

glowing embers (see Figure 8 and Hearth Extensions). If firebox

is to be installed on a raised platform, a Z-type ember protector

(not supplied) must be fabricated to fit your required platform

height (see Figure 7). The ember protector should be made of

sheet metal (28 gauge minimum) to prevent corrosion.

6. Using screws or nails, secure fireplace to framing through flanges

located on sides of fireplace (see Figure 9).

HEARTH EXTENSIONS

A hearth extension projecting a minimum of 20" in front of and a

minimum of 12" beyond each side of fireplace opening is required

to protect combustible floor construction in front of fireplace. Fab-

ricate a hearth extension using a material which meets the following

specifications: a layer of noncombustible, inorganic material having

a thermal conductivity of k = .84 BTU IN/FT

thick. For example, if 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 manu-

facturer or supplier of noncombustible material.

If hearth extension is to be raised, a "Z" type ember protector must

be used (see Figure 7 and Figure 11, page 7).

WARNING: Hearth extension is to be installed

only as shown in Figure 10, page 7.
