HE250 - Installation and Operation Manual 33
6.3.1.1 Raised base installation of more than 4" (R value for the hearth extension not required)
The HE250 may be installed directly on the floor or on a raised combustible or non-combustible base. If the
fireplace is elevated more than 4" (B), an R value for the hearth extension is not required. However, the
upper and lower angle, for the full width of the floor protection, must be protected 2" horizontally and
vertically (E) by a non-combustible material. For example, a sheet metal (not included). Apart from these
two corners, the sheet metal does not have to cover the rest of the wall between the base of the fireplace
and the floor.
Note that the non-combustible hearth extension floor area must extend at least 18" (457 mm) in front of
the hearth as shown in Section 6.3.2: Minimum Heart Extension Requirements.
