Hearth Protection Requirements - Vermont Castings 2115 Installation Manual

B. Hearth Protection Requirements
FLOOR PROTECTION: It is necessary to install a Type I
floor protector.
In the US: The unit may be installed on a combustible floor
if the bottom heat shield is installed and non-combustible
spark & ember protection is used. The bottom heat shield
is required unless the unit will be installed on a completely
non-combustible surface (example: unpainted concrete over
bare earth). There is no required R or K value. The floor
protector should extend 8" (203 mm) from either side of the
loading door, 16" (406 mm) from the front of the unit and 6"
(152 mm) to the rear of the unit. The floor protector must
extend underneath any horizontal run of chimney connector
and extend 2" (51mm) beyond each side.
In Canada, similar floor protection must be provided 18" (457
mm) in front, 8" (203 mm) from the sides and 6" (152 mm) to
the rear of the appliance. Figure 3.8
