3.3 Wall Enclosure Rough Opening

IMPORTANT: If this fireplace is installed on an exterior wall, it must be
insulated the same as any other exterior wall to prevent cold air from
entering the home.
IMPORTANT: Allow a minimum of 6" (152mm) in framing
width dimensions for the combustion air duct pipe, which will
be installed after fireplace has been inserted into framing.
See Figure 3.2 on page 11.
CAUTION: Consider the height of the hearth extension when framing
the opening. The height of a hearth extension material may require the
fireplace to be raised on a platform so the hearth extension material
does not block the air inlet and outlet grills. If the air inlet or outlet grills
are blocked, this may cause the fireplace to overheat.
• Frame the opening to fit fireplace. All required clearances must
be maintained.
• Minimum wall enclosure dimensions: 41-1/2" (1080mm) wide x
38-1/4" (792mm) high x 26-1/4" (667mm) deep.
• If masonry (optional) is to be used, prepare the foundation
necessary to support the full masonry load. A lintel is required to
support the added weight of the masonry construction above
the fireplace.
