Installation  of  brick  should  be 

done after the fireplace is placed 

in a permanent location.

The brick housing panels are already installed in 

the firebox. Each housing is stamped with a letter 

(full size bricks are not stamped). These letters will 

help identify the brick when installing. It is impor

tant to install these bricks exactly as instructed. 

Press the brick firmly into the brick housing until 

it snaps. The groove line on the side of the brick 

will come in contact with the flange on the brick 

housing. This secures the brick into the housing. 

See Figure 20 on page 14.

The bricks are packaged in four separate boxes.
