Chimney Supports
The chimney system is supported by the fireplace for vertical chimney heights less than 20' (6 m) above the hearth. Chimney supports are required if the vertical height exceeds 20' (6 m). Locate chimney supports at ceiling holes or other structural framing at 20' (6 m) heights. Spacing between chimney supports must not exceed 20' (6 m). Use Chimney Support Model SKCS8 for SK8 chimney. (Note: the chimney support can not be mounted directly to the fireplace.) Support provided by elbow straps fulfills the support require- ment only if they are spaced as previously described. (A chimney support is 2¹⁄₂" (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. 9)

Installation
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
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 sheeting material to assure the space around the fireplace is totally protected. (Fig. 4)
When installing the chimney, DO NOT caulk be- tween 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 REQUIRED AIR SPACES ARE MAINTAINED. (Page 14, Fig. 20)
