ROUGH FRAMING DIMENSIONS
Rough Framing Dimensions
The Rough Framing Dimensions must be main-
tained to allow this fireplace to slide into the fram-
ing cavity with a 90
0
elbow installed on the top
starter collar. After the ML47 Fireplace is inserted
into the rough framed cavity, install one 2x4 on
each side adjacent to the side of this fireplace’s
body and one 2x4 on top of the top framing
standoffs to close the air gap and to act as nailing
studs for finishing materials.
If the fireplace is to be recessed in a cavity deeper than 19-1/2”, all framing and finishing materials protruding past the
front face of this fireplace must be of the NON-COMBUSTIBLE variety.
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 fireplace to prevent conducting cold up into
the room.
