Chimney Supports
The chimney system is supported by the replace for
vertical chimney heights less than 30’ (9m) above the
hearth. Chimney supports are required if the vertical
height exceeds 30’ (9m). Locate chimney supports
at ceiling holes or other structural framing at 30’ (9m)
heights. Spacing between chimney supports must not
exceed 30’ (9m). Use Chimney Support Model TCS8A.
(NOTE: The TCS8A cannot be mounted directly to
the replace.) Support provided by elbow straps fullls
the support requirement only if they are spaced as pre-
viously described. (A chimney support is 2Z\x" (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. 6)

Chase Installation
A chase is a vertical box-like structure which encloses
the replace and/or chimney. Chases are typically built
on the outside of the house with replace opening cut
into the outer wall of a room. (Page 4, Fig. 2)
If you need help in determining replace location or how
the chimney system should be run, contact your MHSC
dealer for assistance.
Installation
Insulating Fireplace Enclosure
for Cold Climates
If you live in a cold climate, it is not required but
highly recommended that you insulate replace
enclosure to eliminate cold air penetration as much
as possible.
Insulate base of replace with a noncombustible
insulation rated for a minimum of 300°F. Insulating
is very important for outside wall installations over
a concrete slab. If replace is installed on a platform,
insulation should be placed on top of the platform
before replace is set. (Fig. 7)
When a replace 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 restop at
the rst ceiling level above the replace and enclose
the chase with sheeting material. Insulation may
then be installed above sheeting material to assure
the space around the replace is totally protected.
(Fig. 2)
When installing the chimney, DO NOT caulk be-
tween outer pipe and restop. It is vital that some air
be allowed to ow through this very thin gap.
CAUTION: When installing a replace in an insu-
lated enclosure, be sure all required air spaces
are maintained. (Page 13, Fig. 17)
