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 replace and facing to prevent cold air
leaks. Large gaps can be bridged with berglass rope gas-
ket.
Only non-combustible materials may be used to cover the
metal replace 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.
