In the United States, do not use any other chimney

Guidelines for an Outside Air Supply
Outside air may be introduced to the WinterWarm at
either of two available ports: at the lower left corner of
the back of the cabinet (as viewed from the front), or at
the lower left corner of the left side panel.
An outside air duct must be 3” (75 mm) in diameter,
must be no longer than 20’ (6 m), and must not have
more than three elbows. No part of the outside air duct
(including the outside air inlet) may be higher than the
89"
(2260mm)

cut-out panel on the WinterWarm shroud, and it should
terminate at an outside air source. It may not terminate
in a garage or basement, nor near another fuel-fed ap-
pliance. The air inlet must be covered by a wire mesh
screen (not included) with openings not larger than 1/4”
x 1/4” (6 x 6 mm) to prevent rodents from entering from
the outside. The optional duct kit includes a valve to
close off incoming air when the WinterWarm is not in
use.
Hearth Requirements
Unless the Fireplace System Cabinet will be installed
on a completely noncombustible surface such as
unpainted concrete over earth, a floor protector must
be used in the installation for protection against radi-
ated heat as well as protection against spilled coals and
embers.
Floor protectors must extend at least 8” (203 mm) from
the side of the door opening, making a total width of 40”
(1016 mm). In addition, the floor protector must extend
from the front door opening a minimum of 16” (410 mm) in
the United States and 18”(460 mm) in Canada. (Fig. 31)

protector.

A floor protector must satisfy these requirements.
The approved construction of a floor protector calls for
24 gauge galvanized sheet metal covered with a listed
floor protector material that is at least 7/16” (11 mm)
thick (such as Wonderboard® or Durock®). The floor
protector may be covered with a noncombustible deco-
rative material if desired.
