11.0 Framing
11.1 Wall Enclosure Rough Opening
IMPORTANT
Framing dimensions should allow for wall covering thickness and fireplace facing materials. If using a hearth, adjust rough opening
size as necessary to maintain at least minimum clearance requirements.
Non–combustible facing material
may be applied over (but not directly to) fireplace face. This will prevent facing material from
falling off due to heat expansion. Do not obstruct the flow of ventilation air.
WARNING
Provide adequate clearances around air openings into the combustion chamber. Do not obstruct upper and lower grill openings.
Room air enters through lower passage, is heated and exits through upper passage. Blocking these passages may result in
overheating, creating a potentially hazardous situation.
Determine exact position of your fireplace, including hearth
height, width, and depth (if applicable). If possible, place
fireplace in such a manner that vent termination will be
between two studs, eliminating the need for additional
framing.
Consider height of hearth finish material (stone, brick etc.)
when building fireplace platform.
Install fireplace on hard metal or wood surface extending
the full width and depth of fireplace.
If masonry is to be used (optional), prepare the necessary
foundation for the masonry load. When masonry
construction is used, a lintel iron must be used over top
of fireplace to support the added weight. Never use this
fireplace to support additional weight.
Build hearth to desired size and height. If a hearth
extension is desired, combustible material may be used.
