B. Construct the Appliance Chase
A chase is a vertical boxlike structure built to enclose the gas
appliance and/or its vent system. Vertical vents that run on
the outside of a building may be, but are not required to be,
installed inside a chase.
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.
Walls, ceiling, base plate and cantilever floor of the chase
should be insulated. Vapor and air infiltration barriers should
be installed in the chase as per regional codes for the rest of
the home. Additionally, in regions where cold air infiltration
may be an issue, the inside surfaces should be sheetrocked
and taped (or the use of an equivalent method) for maximum
air tightness.
To further prevent drafts, the ceiling firestops should be
caulked with high temperature caulk to seal gaps. Gas line
holes and other openings should be caulked with high tem-
perature caulk or stuffed with unfaced insulation. If the appli-
ance is being installed on a cement slab, a layer of plywood
may be placed underneath to prevent conducting cold up
into the room.
Fire Risk
• Construct chase to all clearance
specifications in manual.
• Locate and install appliance to all
clearance specifications in manual.
