Rough Framing Dimensions
The Rough Framing Height must be maintained to allow this fireplace and the 90-degree elbow connected directly to the top,
on certain vent systems, to slide into the framing cavity. Once the fireplace is positioned inside the framed cavity, a secondary
nailer stud should be added at a minimum height of 38 inches above the floor level of this fireplace. The nailer stud will allow
for securing facing materials.
Special consideration for vertical
vent systems
If a straight-up vertical vent system is being
considered, the top plate on the front wall of the
chase will need to be notched to allow the proper
1” clearance from the top plate to the vertical
vent pipe. Furthermore, all framing headers and
members that are located within the 1” clearance
requirement to the vent stack or vent components must be positioned on edge (on the 1-1/2” edge) to allow proper clearance
to the vent stack or component.
