Insulating Fireplace Enclosure for
Cold Climates
If you live in a cold climate, it is not required but
highly recommended that you insulate fire-
place enclosure to eliminate cold air penetration
as much as possible.
Insulate base of fireplace with a noncombustible
insulation rated for a minimum of 300°F. Insu-
lating is very important for outside wall installa-
tions over a concrete slab. If fireplace is in-
stalled on a platform, insulation should be
placed on top of the platform before fireplace is
set. (Fig. 10)
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 sheeting 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 FIRE-
PLACE IN AN INSULATED ENCLOSURE, BE
SURE ALL REQUIRED AIR SPACES ARE
MAINTAINED. (Page 14, Fig. 20)
Installation
Chimney Supports
The chimney system is supported by the fireplace for
vertical chimney heights less than 30' (9m) above the
hearth. Chimney supports are required if the vertical
height exceeds 30' (9m) with SK8 chimneys or 20'
(6m) with 3-wall chimneys. Locate chimney supports
at ceiling holes or other structural framing at 30' (9m)
(SK8) or 20' (6m) (3-wall) heights. Spacing between
chimney supports must not exceed 30' (9m) (SK8) or
20' (6m) (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
2¹⁄₂" (64mm) long when installed.)
Angled chimney runs require a support every 6' (1.8m)
in addition to the elbow straps. Chimney supports are
used for this function. (Fig. 9)
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)
