Mantel - Heat & Glo NORTHSTAR-BK Owner's Manual

• 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.
Warning Fire Risk!
Maintain clearances
Use only non-combustible material below standoffs, mate-
rial such as cement board is acceptable.
Framing or finishing material used on the front of, or in
front of, the appliance closer than the minimums listed,
must be constructed entirely of non-combustible
materials (i.e., steel studs, concrete board, etc.).
WARNING! Fire Risk
Hearth & Home Technologies is not responsible for discol-
oration, cracking or other material failures of finishing ma-
terials due to heat exposure or smoke.
