2. Framing the Fireplace
The North Star Fireplace will fit the framed opening width of
43-7/8" tall. The finished cavity depth must be no less than 24".
Framing must extend straight up all the way to the ceiling.
Figure 10A shows a typical framing (using 2 x 4 lumber) of the
fireplace, assuming combustible materials are used. All required
clearances to combustibles around the fireplace must be adhered
to. Any framing across the top of the fireplace must be above
the level of the top standoffs.
CLEARANCES!
A minimum 1" air clearance must be maintained at the back and sides
of the fireplace assembly.
Chimney sections at any level require a 2" minimum air space
clearance between the framing and chimney section.
WARNING!
Do not apply combustible finishing materials over
any part of the front of this fireplace or a structure
fire may result. The metal fireplace face may only
be covered with noncombustible materials such
as ceramic tile, brick, or stone. Do not cover or
block any cooling air slots.

When planning your fireplace location, the chimney construction and necessary clearances must be considered. The fireplace
system and chimney components have been tested to provide flexibility in construction. The following figures are the minimum
distances from the base of the fireplace.
1. Min overall straight height
2. Min height with offset/return
3. Max height
4. Max chimney length between
an offset and return
