1.The minimum depth must be maintained from the floor of the fireplace to a height of 16” (416 mm).

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 fire- places, 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.

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 Fire- place Insert and the mantel, top trim and side trim can- not 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” (1219 mm) 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.

*The mantel and/or top trim must be 9” (229 mm) 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” (1067 mm). Measure the side clearance (C) from the exact center of your fire- place 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-com- bustible 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” (203 mm) from the side of the door opening, making the protector 40” (1016 mm) wide. In addition, the floor protector must extend from the front door opening a minimum of 16” (410 mm) in the United States and 18”(457 mm) in Canada.
