Optional Cast Facade installation

Install the Facade per instructions provided in 

Facade Kit (ordered separately - see 

Page 27

).

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

 

16 and 17

):

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

lumber.

B. WARNING:  Combustible materials can-

not 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) mea-

sured 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 16

). 

 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 sup-

port 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 WRT3920WS 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 14

).

* The safety metal strip must cover the entire 

width of the fireplace
The combustible floor in front of the fireplace 

must be covered with at least a 1/2 inch of 

non-combustible material (tile, marble, stone, 

etc). See 

Figure 15

.

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).

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

Hearth extension of an elevated fireplace 

must respect the same minimal dimensions 

as a fireplace installed directly on the floor.

Figure 14 - Hearth Extension Requirements

The crack between the fireplace 

and the hearth extension must be 

sealed with a non-combustible ma-

terial such as sand-cement grout.
