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).  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 fireplace.) 
 Support provided by elbow straps fulfills 
the support requirement only if they are spaced as pre-
viously 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. 6)

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 5, Fig. 2)
If you need help in determining fireplace location or how 
the chimney system should be run, contact your Ver-
mont Castings 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 
insulation 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 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. 2)
When installing the chimney, DO NOT caulk between 
outer pipe and firestop. It is vital that some air be al-
lowed 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)
