Constructing 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 building.
These instructions are not substitutes for the requirements
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 oor of the chase
should be insulated. Vapor and air in ltration barriers should
be installed in the chase as per regional codes for the rest of
the home. Additionally, in regions where cold air in ltration
may be an issue, the inside surfaces may be sheetrocked
and taped for maximum air tightness.
To further prevent drafts, the wall shield and ceiling restops
should be caulked with high temperature caulk to seal gaps.
Gas line holes and other openings should be caulked with
