Masonry Veneer Construction Details
Brick, stone or other masonry veneer finished fronts to
Fire-Lite fireplaces are possible. Special attention is required with
regards to:
(1) the placement of the proposed masonry veneer facing and its
interface with the Fire-Lite fire brick lining, and
(2) Clearance to combustible framing and sheathing from any
steel “L” support used in the masonry veneer around the front of
the Fire-Lite unit behind the veneer facing.
Any proposed brick, stone or other masonry veneer
facing must have sufficient foundation to support the full weight
of the veneer work. This may require review by a local structural
engineer prior to construction.
The veneer facing, when installed, must present a tight
seal with the leading edge - the room edge - of the Fire-Lite fire
brick lining at the sides of the Fire-Lite firebox opening. (Figure
37)
A steel “L” will need to span the top of the finished
fireplace opening to carry the masonry veneer as it spans over the
Fire-Lite firebox opening. (Figures 36-38)
By code requirement this steel “L” must have a mini-
mum four inch (4”) end bearing. This bearing surface area shall
be provided in the veneer work. (Figure 39) It is important that
the steel “L” is set tight against the Fire-Lite’s damper beam front
and set in a mud joint to avoid creating a “false chimney” be-
tween the back of the steel “L” and the Fire-Lite’s damper beam
front. (Figure 40)
Steel “L” or “angle” used to support masonry veneer
as it spans the Fire-Lite’s firebox opening must, in all cases,
have a two inch (2”) minimum clearance to all combustible
materials. The vertical leg of the steel “L” cannot exceed six
inches (6”) in height.
Note:
Properly placed combustible sheathing is kept a mini-
mum of eight inches (8”) away from the Fire-Lite firebox
opening sides and top.
Important:
Combustible framing members, normally set at
one and one-half inch (1-1/2”) clearance to the sides of the
Fire-Lite firebox must be moved to at least two inch (2”)
clearance to the firebox sidewalls to maintain minimum two
inch (2”) clearance to the steel “L” to avoid a potential fire
hazard.
Moving framing members two inches (2”) away
from the firebox side walls will maintain the minimum re
-
quired two inch (2”) clearance from the steel “L” and, at the
same time allow full four inch (4”) end bearing required for
the steel “L”. (Figure 39)
