FRAMING
3.3 Framing Clearances and Mantle
A chase is a vertical box-like structure built to enclose the gas fireplace and its vent system. In cooler
climates the vent should be enclosed inside the chase.
NOTICE: Treatment of ceiling firestops and wall shield firestops and construction of the chase
may vary with the type of building. These instructions are not substitutes for the requirements
of local building codes. Therefore, you MUST check local building codes to determine the
requirements to these steps.
A chase 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 may be sheet
rocked and taped (or an equivalent method may be used) to achieve maximum air tightness.
To further prevent drafts, the wall shield and ceiling firestops should be caulked with caulk rated for a
minimum of 300°F continuous exposure rating to seal gaps. Gas line holes and other openings should
be caulked or stuffed with unfaced insulation.
If the fireplace is being installed on a cement surface, a layer of plywood may be placed underneath to
prevent conducting cold up into the room.
Attention:
Cold climate installation recommendation: When installing this fireplace against a non-
insulated exterior wall, it is recommended that the outer walls be insulated to conform to applicable
insulation codes.
WARNING
Before building the framing, make sure to remove the
glass door latch tool secured to the top of the left side for
shipping. This tool is needed to open the glass door.
