Step 9. Finishing
Figure 37 shows the minimum vertical and corresponding
maximum horizontal dimensions of fireplace mantels or other
combustible projections above the top front edge of the
fireplace. See Figures 2 and 3 for other fireplace clearances.
Only non-combustible materials may be used to cover the
black fireplace front.
WARNING: WHEN FINISHING THE FIREPLACE,
NEVER OBSTRUCT OR MODIFY THE AIR IN-
LET/OUTLET GRILLES IN ANY MANNER.

CAUTION: IF JOINTS BETWEEN THE FINISHED WALLS
AND THE FIREPLACE SURROUND (TOP AND SIDES)
ARE SEALED, A 300°
F. MINIMUM SEALANT MATE-
RIAL MUST BE USED. THESE JOINTS ARE NOT RE-
QUIRED TO BE SEALED. ONLY NON-COMBUSTIBLE
MATERIAL (USING 300° F. MINIMUM ADHESIVE, IF
NEEDED) CAN BE APPLIED AS FACING TO THE FIRE-
PLACE SURROUND. SEE THE DIAGRAM BELOW.
Hearth Extensions
A hearth extension may be desirable for aesthetic reasons.
However, ANSI or CAN/CGA testing standards
do not
require
hearth extensions for gas fireplace appliances.

Installing the Trim
Combustible materials may be brought up to the specified
clearances on the side and top front edges of the fireplace,
but
MUST NEVER
overlap onto the front face. The joints
between the finished wall and the fireplace top and sides
can only be sealed with a 300° F. (149° C) minimum sealant.
WARNING: WHEN FINISHING THE FIREPLACE,
NEVER OBSTRUCT OR MODIFY THE AIR INLET/
OUTLET GRILLES IN ANY MANNER.
Install optional marble and brass trim surround kits as
desired. Marble, brass, brick, tile, or other non-combustible
materials can be used to cover up the gap between the
sheet rock and the fireplace.
Do not obstruct or modify the air inlet/outlet grilles. When
overlapping on both sides, leave enough space so that the
bottom grille can be lowered and the trim door removed.
