for detail.
** 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 the 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 5" (127 mm) higher than the combustible floor in front of it and a floor protection
must extend at least 16" (406 mm USA) and at least 18" (457 mm Canada) without an R
value. If the hearth elevation is lower than 5" (127 mm), the non-combustible (B) floor
protector in front of the insert should have an R value equal or greater than 1.00 and shall
extend 23" (584 mm) in front of the unit.
