Rough Framing Dimensions

The Rough Framing Dimensions must be maintained to allow this fireplace to slide into the framing cavity and to provide

the required clearances to the combustible framing structure.

Constructing the Appliance Chase

A chase is a vertical box-like structure built to enclose this fireplace and 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 adhered to.

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.

Wall, 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 of the chase may be sheet rocked and taped for maximum air tightness.

To further prevent drafts, the fire stops should

be caulked with high temperature caulk to seal

the gaps. Gas line holes and other openings

should be caulked with high temp caulk or

stuffed with unfaced insulation. If the appliance

is being installed on a cement slab, a layer of

plywood may be placed underneath this fire-

place to prevent conducting cold up into the

room.
