Floor Protection
A tremendous amount of heat radiates from the bottom plate of your stove. The floor area directly under and around the stove will require protection from radiant heat as well as from stray sparks or embers that may escape the firebox.
Heat protection is provided through the use of a Ver- mont Castings Bottom Heat Shield #1905. Spark and ember protection must be provided by a floor protector constructed with noncombustible material as specified.
Most installations will require the bottom heat shield be attached. Only when the stove is placed on a complete- ly noncombustible surface such as unpainted concrete over earth may it be used without the heat shield.
Even when the bottom heat shield is installed, you must provide special protection to the floor beneath. For installations with the heat shield attached, use a non- combustible floor protector such as 1/4” nonasbestos mineral board or equivalent, or 24 gauge sheet metal. The floor protector may be covered with a noncombus- tible decorative material if desired. Do not obstruct the space under the heater.
Protection requirements vary somewhat between the Untied States and Canada as follows:
In U. S. installations the floor protector is required under the stove and must extend at least 16” (not including the ash lip) from the front of the stove (“F”, Fig. 12), and at least 6” from the sides and rear. (“D” and “E”, Fig. 12)
It must also extend under the chimney connector and 2” to either side. (“C”, Fig. 12) For the 8” (203 mm) connector, the protector must be a minimum of 12” (305 mm) wide. For the 6” (152 mm) connector, the protector must be 10” (254 mm) wide. The protector must be centered under the connector.
To meet these requirements, a floor protector must be at least 42” wide and 43” deep.
In Canada: A noncombustible floor protector is required under the stove as well. The floor protector must extend 18” (457 mm) to the front (“F”, Fig. 12), and 8” (203 mm) from the sides and rear. (“D” and “E”, Fig. 12)
To meet these requirements, a floor protector must be at least 46” (1168 mm) wide and 47” (1194 mm) deep.

Floor Protection for Fireplace Installation
Do not assume that your fireplace hearth is completely noncombustible. Many fireplace hearths do not satisfy the “completely noncombustible’ requirement because the brick or concrete in front of the fireplace opening is supported by heavy wood framing. Because heat passes readily through brick or concrete, it can easily pass through to the wood. As a result, such fireplace hearths can be a fire hazard and are considered a com- bustible floor.
