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 fl oor of the chase should be insulated. Vapor and air infi ltration barriers should be installed in the chase as per regional codes for the rest of the home. Additionally, in reagions where cold air infi ltration may be an issure, the inside surfaces be sheetrocked and taped for maximum air tightness.
To further prevent drafts, the ceiling fi restops 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.
