Framing, Facing And Mantel

The construction of the framing, facing, and 

mantel must be in accordance with the stan-

dards and the following illustrations (

Figures 

9, 10 and 11):

A.  Frame the fireplace using 2” x  3” or heavier 

lumber.

B. 

WARNING:  Combustible materials 

cannot be used in the space directly 

above the fireplace, except for the 

studs above the facade that support 

the facing and mantel.  This area must 

remain empty for a height of 6’8” 

(2,032 mm) measured from the base 

of the appliance.

C.  Frame the fireplace with vertical studs at the 

sides of the fireplace running from floor to 

ceiling (see 

Figure 11). 

 If combustible facing 

is to be used, position the studs back, from 

the front edge of the fireplace (a space that 

is the thickness of the facing material, so 

that the facing can be installed flush with the 

fireplace facing).  Frame headers between 

the vertical studs only as follows:

• 

Place 2” x 3”  or  2” x 4” headers, 

only along the upper part of the front, 

side and back faces (some codes 

may require a 2” x 6 ” on an outside 

bearing wall).  Do not put wood or any 

combustible material within the area 

above the fireplace except on the front 

facing.

• 

Place headers only as required to support 

the facing and mantel.

D. 

WARNING: The fireplace must not be in 

contact with any insulation or loose fill-

ing material. Cover the insulation with 

Drywall panels around the fireplace.

Hearth Extension Requirements

The WRT4820WS fireplace may be installed 

directly on a combustible floor. The supplied 

safety metal strip must be positioned as follows:  

One half under the front of the fireplace and the 

other half must extend on the floor over which 

the hearth extension will be built (see 

Figure 9).

*   The safety metal strip must cover the entire 

width of the fireplace

The combustible floor in front of the fireplace 

must be covered with a non-combustible 

material (tile, marble, stone, etc). See 

Figures 

9 and 10

.

COLD CLIMATE INSTALLATIONS

Climates where temperatures will fall below 

32° F (0° C).

The heating performance of the appliance will 

vary depending upon the level of insulation, 

house design, how the appliance is operated, etc.
If this fireplace is being installed in a cold 

climate, it is especially important to seal all 

cracks around the fireplace and wherever cold 

air could enter the room with noncombustible 

material.

Also, the outside air inlet duct should be wrapped with noncombustible insulation to minimize 

the formation of condensation. Do not place insulation materials directly against the chimney 

sections.  We recommend that you use the insulated wall radiation shield since it will maintain 

the home’s thermal barrier. AC chimney is NOT recommended in very cold climates (in areas with 

temperatures below 32°F (0°C).

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

WARNING: THE HEARTH EXTEN-
SION IS TO BE INSTALLED ONLY

The crack between the fireplace 

and the hearth extension must be 

sealed with a non-combustible 

material such as sand-cement 

grout.

 Elevated fireplace installations re-

quire a special “Z” Metal Safety Strips 

(field provided), in place of the safety 

metal strip shown above. The safety 

strip should extend the full width of 

the fireplace.  When more than one 

safety strip is used they must overlap 

by a minimum of 1”.  Hearth extension 

of an elevated fireplace must respect 

the same minimal dimensions as a 

fireplace installed directly on the floor
