Chimney Supports
The chimney system is supported by the fireplace for verti-
cal chimney heights less than 30' (9 m) above the hearth.
Chimney supports are required if the vertical height exceeds
30' (9 m) with SK8 chimneys or 20' (6 m) with 3-wall chim-
neys. Locate chimney supports at ceiling holes or other
structural framing at 30' (9 m) (SK8) or 20' (6 m) (3-wall)
heights. Spacing between chimney supports
must not
exceed 30' (9 m) (SK8) or 20' (6 m) (3-wall). Use Chimney
Support Model SKCS8.
(NOTE: The SKCS8 can not be
mounted directly to the fireplace.)
Support provided by
elbow straps fulfills the support requirement only if they are
spaced as previously described. (A chimney support is 2
¹⁄₂
"
(64 mm) long when installed.)
Angled chimney runs require a support every 6' (1.8 m) in
addition to the elbow straps. Chimney supports are used
for this function. (Fig. 10)
Chase Installation
A chase is a vertical boxlike 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 5, Fig. 5)
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. 11)
When a fireplace is installed in a chase or on an 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. 5)
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 INSULATED ENCLOSURE, BE SURE ALL RE-
QUIRED AIR SPACES ARE MAINTAINED.
