B36LA8 & B36RA8 Woodburning Fireplaces

TRIM INSTALLATION

TRIM INSTALLATION

The face of your fireplace may be left exposed or trimmed with any noncombustible material such as brick, 
stone or marble. 

Figure 30.

 If a noncombustible trim is installed, be sure it is fastened snugly to the face of 

the fireplace. A crack between the material and the face of the fireplace could pose a fire hazard and impair 
the proper operation of the fireplace. Blocking the fireplace with framing and attaching the base to the sup-
porting floor will further reduce the possibility of such a crack developing.

CAUTION:

 Do not allow any trim materials to extend closer than 3/8” to the vertical edges of the firebox 

opening if you plan to equip the fireplace with glass doors.
Wall ties should be fastened to the face of the fireplace with sheet metal screws and placed in the mortar 
joints of masonry trim.
Combustible material must not be installed below the top spacers of the fireplace or overlap the sides of 
the fireplace face.  Seal the face of the fireplace to the surrounding wall with noncombustible caulk or trim 
materials to prevent cold air leakage around the fireplace.

CAUTION:

 No trim should block or restrict in any way the flow of air into the air inlets in the face of the 

fireplace. 

Figures 30 and 31

Be sure to provide the required floor protection as described in a preceding section of this manual. Page 
13, 

Figure 10

Combustible mantels and trim must be installed in accordance with the National Fire Protection Association 
- ANSI NFPA 211 Standard - Section 7-2.3.3.

Glass Door Installation

This fireplace has been tested and listed for use with Model MGD36B or MGD36PB glass doors. For instal-
lation of the Model MGD36B or MGD36PB glass doors, refer to the instructions provided with the doors.

NOTE:

 On B36LA8 or B36RA8 Models, noncombustible facing materials may be installed to the 

top of the fireplace opening. This facing material must be secured and sealed to the face of the 
fireplace. Failure to properly secure and seal noncombustible facing material to the fireplace can 
cause a possible fire hazard and will void the warranty.
