Heatiator C40 F. Mantel, •Non-CombustibleSealant Material, •Cardboard OR Metal Template

•Non-Combustible Sealant Material

Sealants which will not ignite and burn: Super Calstick

After completing the framing and applying the facing mate-

rial (drywall) over the framing, a bead of non-combustible sealant must be used to close off any gaps at the top and sides between the fireplace and facing to prevent cold air leaks. Large gaps can be bridged with fiberglass rope gas- ket.

Only non-combustible materials may be used to cover the metal fireplace front.

•Cardboard OR Metal Template

A cardboard template of the front is printed on the outside of the shipping box. It measures 1/8 in. (3 mm) bigger all the way around than the actual front. Cut out the template along the outside of the line for use in your installation.

A metal template is also available for more durable continued use remaining accurate over time. See page 64 for catalog number.

F. Mantel

A combustible mantel may be positioned no lower than 60 in. (1524mm) from the base of the fireplace.

The combustible mantel may have a maximum depth of 12 in. (305mm). Combustible trim pieces that project no more than 3/4 in. (19mm) from the face of the fireplace can be placed no closer than 6 in. (152mm) from the side of the decorative front. See Figure 10.9

Combustible trim must not cover:

•the metal surfaces of the fireplace

•where the non-combustible board is placed over the metal surfaces

•the space between the metal face of the fireplace and framing members.

Refer to page 37 for clearance requirements
