WinterWarm Fireplace Insert or System

Clearance Requirements
After confirming that your fireplace is the right size,
check the clearances to combustibles. First mark with
tape the exact center of your fireplace opening on the
hearth. Measure the side clearance from this point.
Measure the top trim and/or mantel clearances from the
finished hearth surface. Measure the front clearance (to
furnishings, etc.) from the fireplace face.
NOTE: The clearance between the WinterWarm
Fireplace Insert and the mantel, top trim and side trim
cannot be reduced by installing shields.
Another clearance requirement to consider is that for
movable items such as tables, bookcases, rugs,
furnishings, and your woodbox. All combustible materi-
als of this type should be a minimum of 48" (1219mm)
from the front surface of the WinterWarm. Be sure that
family members are aware of this requirement as well,
so they too will keep objects a safe distance from the
WinterWarm.

1. The minimum depth must be maintained from the floor of the
fireplace to a height of 16” (416mm).
2. These are the minimum damper dimensions required for use of
the Vermotn Castings Flex Connector System.
3. Though the WinterWarm Fireplace Insert will fit into larger
fireplaces, the decorative surround panels will not completely cover
the fireplace opening if these dimensions are exceeded. Custom
made trim may be used.
Fig. 19 Use thes measurements to confirm that the Winter-
Warm will fit into your masonry fireplace.

*The mantel and/or top trim must be 9” (229mm) in depth or less.
For the WinterWarm System, measure from the supplied trim
panel forward.
**Where side trim extends more than 2” (52mm) from the fireplace
facing, the side clearance must be no less than 42” (1067mm).
Measure the side clearance (C) from the exact center of your
fireplace opening on the hearth (X). Measure the top trim (B) and/
or mantel clearances (A) from the finished hearth surface.
Measure the front clearance (to furnishings, etc.) from the
fireplace face.
Fig. 20 Observe these clearances to combustible trim.
Hearth Requirements
In some fireplaces, the hearth in front of the fireplace
opening is brick, stone, slate, or some other non-
combustible material that is in direct contact with
concrete poured over earth. These are the only hearths
that are considered noncombustible.
In other fireplaces, the brick or concrete hearth in front
of the fireplace opening is supported by heavy wooden
framing. Because neither brick nor concrete has good
insulating properties, heat radiated by the fire will pass
downward through the hearth to the wooden framing.
Such hearths are considered combustible.
Unless the fireplace and hearth are constructed over a
completely noncombustible surface (such as unpainted
concrete over dirt), a floor protector must be used in
WinterWarm Fireplace Insert installations in front of and
to the sides of the door as protection against spilled
coals and embers.
Floor protectors must extend at least 8" (203mm) from
the side of the door opening, making the protector 40"
(1016mm) wide. In addition, the floor protector must
extend from the front door opening a minimum of 16"
(410mm) in the United States and 18"(457mm) in
Canada.
