Chase Installation
A chase is a vertical box-like structure which encloses the
fireplace and/or chimney. Chases are typically built on the
outside of the house with fireplace opening cut into the
outer wall of a room. (Page 4, Fig. 2)
If you need help in determining fireplace location or how
the chimney system should be run, contact your Vermont
Castings Group dealer for assistance.

Insulating Fireplace Enclosure
for Cold Climates
If you live in a cold climate, it is not required but
highly
recommended
that you insulate fireplace enclosure to
eliminate cold air penetration as much as possible.
Insulate base of fireplace with a noncombustible insula-
tion rated for a minimum of 300°F. Insulating is
very
important
for outside wall installations over a concrete
slab. If fireplace is installed on a platform, insulation
should be placed on top of the platform
before
fireplace
is set. (Fig. 7)
When a fireplace is installed in a chase or on a outside
wall, enclosure should be treated like any outside wall
in a home. Insulation should be installed on the inside
wall as well as the outside wall(s). In a chase, it is also
a good idea to install a firestop at the first ceiling level
above the fireplace and enclose the chase with sheeting
material. Insulation may then be installed above sheet-
ing material to assure the space around the fireplace is
totally protected. (Fig. 2)
When installing the chimney,
DO NOT
caulk between
outer pipe and firestop. It is vital that some air be allowed
to flow through this very thin gap.
CAUTION: When installing a fireplace in an insu-
lated enclosure, be sure all required air spaces are
maintained. (Page 13, Fig. 17)
Framing
Framing can be constructed before or after the fireplace
is set in place, however, most installers build the frame
before setting the fireplace.
Frame fireplace with 2 x 4 lumber or heavier materials.
Refer to framing dimensions in Figure 1 for basic fireplace
specifications.
NOTE:
Framing should be positioned to accommodate
wall covering and fireplace facing material.
