Air Flow Clearance
A
4-inch
clearance from the heat barrier vent openings along the top of the fireplace is required. Framing and building material is
NOT
permitted in this area. Doing so will block the vents and cause the entire surrounding to overheat.
NOTE: It is acceptable if the flat stud immediately above the fireplace hangs over heat barrier vents
slightly
when using
standard metal framing (as shown in diagram above).
Framing Clearance
Maintain a minimum
1
/
4
inches
of space between the framing and the face of the fireplace.
