3.2.2 Chimney Specifications
WARNING: Any chimney clean-outs must fit properly.
This fireplace insert is to be installed into a solid fuel masonry or
factory built non-combustible fireplace that has been installed in
accordance with the national, provincial, state, and local building
codes.
The existing chimney must be comprised of one of the following:
•
Factory-built solid fuel chimney: 7" (178mm) minimum inside
diameter
•
Masonry chimney: 6" x 8" (152mm x 203mm) minimum inside
diameter
Existing chimney height:
•
Minimum: 10' (3.05m) Maximum: 50' (15.24m)
In certain circumstances where a chimney no longer terminates
through the roof line, a co-linear to co-axial adapter may be installed
where the existing chimney ends. After the adapter, the co-axial pipe
must maintain 1" (25mm) clearance to combustibles on all sides of the
vent pipe. Refer to Sections 4.2 (pg. 13) and 6.3 (pg. 16) for other
co-linear to co-axial conversion considerations and requirements.
3.2.2.1 Determine Length of Existing Chimney
1.
Remove and discard existing chimney cap.
2.
NOTE: It is helpful to have two people complete this step.
Position one person at the fireplace opening and another person
at the top of the chimney.
3.
Measure from the fireplace base to the top of the chimney.
4.
Subtract the height of the insert from the previous
measurement.
5.
This is the total length of the co-linear flexible aluminum pipe
required for your installation. If using Kozy Heat #816, cut to
length.
