IMPORTANT NOTE
These dimensions are guidelines only. Features in your
fireplace may change for minimum size requirements.
IMPORTANT NOTE
If the fireplace lintel is wider than 8” (203mm), the height
of the fireplace opening may need to be increased a few
inches to allow for a gradual offset in the exhaust and/or
intake vent pipes.
