heat shield.
EXAMPLE: The rear clearance defined for a Model B (FIGURE 1 and TABLE) measurement B, is listed as twenty
inches (20”, 500mm.) This rear clearance, for a Model B may be reduced up to 66% but never less than twelve inches
(12”, 300mm) by using either of the wall protection procedures listed in ITEM 5 and ITEM 6.
5. Tested and Listed Wall Protectors: Clearances to combustibles may be reduced if a tested and listed wall
protector is installed over a combustible surface when the following conditions exist:
a. A dead air space of 1” must separate the tested and listed wall protector from the combustible wall
surface.
b. The tested and listed wall protector must extend from floor to ceiling with a full 1” clearance for air
circulation. This air circulation must be between the combustible walls and the tested and listed wall protector all the way
from the floor to the ceiling.
c. Spacers ( preferably 1”ceramic rather than metal ) must be located at the corners on the tested and listed
wall protector rather than behind the heater or the chimney connector.
6. Untested and Unlisted Wall Protectors: Untested and Unlisted Wall Protectors may be constructed of masonry,
24-gauge metal or thicker sheet metal, or non-combustible half-inch (0.5”, 12.5mm) thick insulation board. If
untested and unlisted protectors are used, then Item 5a, 5b, and 5c above must be modified to read one and a half
inches (1.5”, 37.5mm) instead of the 1” separation.
NOTE: If the installer plans to use a reduced clearance by using double wall chimney connectors as shown in
TABLE 1, then the stove clearances may not be further reduced by utilizing any of the methods listed in ITEM 5
or ITEM 6.
