Directly on the floor (R value for the hearth extension not required)
In the case where the fireplace is installed directly on the floor the joint between the hearth extension and
the fireplace (
E
) must also be protected by a non-combustible material. For example, a piece of sheet metal
(not included). See Figure 17 : Installation Directly on the floor.
CAUTION
•
THE FLOOR UNDER THE FIREPLACE SHOULD MATCH OR EXCEED THE HEIGHT OF THE FLOOR
PROTECTION.

A noncombustible floor protection must be installed in front of the unit. For more details, see section 1.3.8 -
Minimum Hearth Extension Requirements. The use of an R value is convenient when more than one
material is going to be used in the hearth extension to cover the combustible surface. This is because R
values are additive, whereas K values are not. To find the corresponding R factor to use for some selected
materials, see
Table 3 : Thermal Characteristics of Common Floor Protection Materials

CAUTION
DO NOT LEAVE CARPET UNDER THE FLOOR PROTECTION IN FRONT OF THE FIREPLACE.
