EXTENDED ROOF BRACKET
INSTALLATION
If the chimney extends more than 4 feet above
the rooine, an Extended Roof Bracket must
be installed at every 4-foot increment of height
above the rooine, leaving no more than 4 feet
extending above the last pipe band.
1. Mount Pipe Band: Slip the Pipe Band
around the chimney and secure by tightening
the nut and bolt.
2. Install Roof Brackets: Measure from the
Pipe Band to the points where the conduit will
meet the roof, and form approximately a 60°
angle with the chimney, and with each other.
(Figures 18 and 19). Cut 2 pieces of 3/4 inch
thin wall galvanized steel electrical conduit, (or
rigid galvanized tubing) to these lengths. The
conduit is not furnished by Simpson Dura-Vent,
and must be locally procured. Mount the two
Roof Brackets where the conduit meets the
roof, using 6 roong nails per bracket. Seal
the nail heads carefully with a non-hardening,
waterproof sealant.
3. Attach Conduit: Flatten 1 inch and drill
a 1/4-inch hole at each end of both pieces of
conduit. Bolt each conduit to the Pipe Band
and Roof Brackets with the nuts and bolts
provided.
