1.The minimum depth must be maintained from the floor of the fireplace to a height of 21¹⁄₂” (540mm)

2.Though the WinterWarm Small Insert will fit into larger fireplaces, the decorative optional CFM Corporation Surround Panels will not completely cover the fireplace opening if these dimensions are exceeded. Custom made trim pieces may be used.

Fig. 3 Use these measurements to confirm that the Winter- Warm Small Insert will fit into your masonry fireplace.

Clearance Requirements

After confirming that your fireplace is the right size, check the clearance 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. (Fig. 4)

Fireplace Clearances

A. Mantel*	34” (865mm)
B. Top Trim*	34” (865mm)
C. Side Trim**	20¹⁄₈” (510mm)

*for more details on mantel and top trim, see Note below. ** Where side trim extends more than 2” (50mm) from the fireplace facing, the side clearance must be no less than 20⁵⁄₈” (525mm).

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. 4 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 nei- ther 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 non-combustible surface (such as unpainted concrete over dirt), a floor protector must be used

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 41” (1041mm) wide. In addition, the floor protector must extend from the front door opening a minimum of 16” (406mm) in the United States and 18” (457mm) in Canada. (Fig. 5)
