of combustible materials.
If a finishing material is installed inside the enclosure, its thickness must be added to the following
measurements.
The M and N values are minimum measurements and may need to be increased to allow the
installation of the fresh air intake, the forced air distribution or the type of finishing material
used.
M : Framing depth 53 ½" (1359 mm)
N : Framing width (Installation with centered fireplace) 75 ½" (1918 mm)

too tight duct curves. Smaller dimensions can be used depending on the size and type of duct as well as the configuration of the installation.
HVAC duct, as per ULC S110 or UL 181, class 0 or class 1, must withstand temperatures up to 250oF.
