* For a 8" (203 mm) mantel shelf. See Section 8.3 Compliance of a Combustible
Mantel Shelf for other mantel shelf dimensions. Note that you can reduce the
combustible mantel shelf clearance with the use of a Heat Shield, sold separately.
See Appendix 4: Top Surround and Mantel Shelf Heat Shield Installation
(AC01317) for détail.
** Where a fresh air intake is needed, we suggest you add a minimum of 4'' to the
width of the minimum masonry opening.
Note 1: From door opening. The depth of hearth extension in front of the insert is
included in the calculation of the floor protector's dimensions. The masonry hearth
should be at least 4 inches (102 mm) higher than the combustible floor in front of it. If
the hearth elevation is lower than 4 inches, the non-combustible (B) floor protector in
front of the insert should have an R value equal or greater than 2.00 and shall extend
29 inches (737 mm) in front of the unit.
