Vermont Casting CR36L Chase Installation, Insulating Fireplace Enclosure For Cold Climates

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 4, Fig. 2)

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 non-combus- tible 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 sheet- ing 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 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 12, Fig. 17)
