D. Secure Offset/Return

E. Install Ceiling Firestops

CAUTION!

Risk of Fire!

Ceiling firestops must be used

whenever the chimney penetrates a ceiling/floor.

• Chase construction requires ceiling firestops at each

floor or every 10 ft. (3.05 m) of clear space.

• The ceiling firestop slows spread of fire and reduces

cold air infiltration.

• Install a ceiling firestop whenever chimney penetrates

ceiling/floor.

• Mark and cut an opening in ceiling as shown in Figure 5.4.

• Frame the opening with the same size lumber used in

the ceiling joists.

• Nail the ceiling firestop to the bottom of the ceiling joists

when there is a room above.

• Use an attic insulation shield if the ceiling is insulated.

The ceiling firestop may then be attached above or below

the joists.

WARNING! Risk of Fire! DO NOT

seal area between

firestop opening and chimney pipe except where they en-

ter the attic or leave the warm air envelope of the home

(use 600° F sealant).

Figure 5.4 Installing the Ceiling Firestop

When offsets and returns are joined to straight pipe sec-

tions, they must be locked into position with the screws

provided* (outer only), using the predrilled holes. To pre-

vent gravity from pulling the chimney sections apart, the

returns and the chimney stabilizers have hanger straps for

securing these parts to joists or rafters. See Figure 5.3.

* Use # 6 or # 8 sheet metal screw, or larger, no longer

than 1/2 in. (13 mm).

WARNING! Risk of Fire!

• Secure offsets with screws (not to exceed 1/2 in./13 mm

In length).

• Secure returns with strapping.

• Straight chimney sections may be secured with screws

(not to exceed 1/2 in./13 mm In length) at the joints.

• Keep chimney sections from separating or twisting.
