Stratford Fireplace Installation and Operation Manual
6.3.1.1 Raised base installation of more than 4" (R value for the hearth extension not required)
The Stratford 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 16" (41 cm) in
front of the hearth as shown in Section 6.3.2: Minimum Hearth Extension Requirements.
