Positioning the Unit
It is necessary to have a floor protection made of non-combustible materials that meets the
measurements specified in table
FLOOR PROTECTION
(see
Section 8.5
. To determine
the need to add floor protection (D) beyond the hearth extension, you must do the
following calculation using the data in Table
Data for floor protection calculation
of this
section: D = B - (A - C). If the value (D) is negative or zero, you do not have to add more
floor protection in front of the unit, because the masonry fireplace hearth extension is large
enough. If the value (D) is positive, you will need floor protection in front of the hearth
extension at least equivalent to the result (D).
Here is a sample calculation to determine the need to add a non-combustible materials
floor protection. For someone living in the USA whose insert would protrude 3" (76 mm)
into the room (C) the calculation would be:
Value D = B - (A - C)
Value D = 16" - (16" - 3")
Value D = 16" - 13"
Value D =
3"
Non-combustible floor protection of at least
3" (76 mm)
in depth must be installed in front
of the fireplace hearth extension.
