A chase is a vertical boxlike structure built to enclose the
replace and/or its vent system. Vertical chimneys that run
on the outside of a building must be installed inside a chase.
In cold climates, it is recommended that the chase insulated
using batt type insulation between the joists.
Construction of the chase may vary with the type of build-
ing. These instructions are not substitutes for the require-
ments of local building codes. Local building codes MUST
be checked.
Chases should be constructed in the manner of all outside
walls of the home to prevent cold air drafting problems. The
chase should not break the outside building envelope in any
manner. All outer walls need to be insulated.
Building codes require false ceiling and ceiling restops at
each oor of the chase or every 10 ft (3.05 mm) of clear
space to control spread of re.
Walls, ceiling, base plate and cantilever oor at the rst level
of the chase should be insulated. See Figure 9.1 Vapor and
air inltration barriers should be installed in the chase as per
regional codes for the rest of the home. Additionally, Hearth
& Home Technologies recommends that the inside surfac-
es be sheet rocked and taped (or the use of an equivalent
method) for maximum air tightness.
Holes and other openings should be caulked with high tem-
perature caulk or stuffed with unfaced ber glass insulation.
