ELBOW INSTALLATION
1. IHP provides a 15
(SPSE15) and 30
°
chimneys to avoid framing members or roof peaks. A maximum
of 30
from the vertical is allowed, and a total of four elbows (two
°
pair) for each chimney installation. Maintain 2" clearance to com-
bustibles.
2. Attach the elbow(s) to the chimney pipe or other support part and
push to lock. Using the offset chart, add chimney sections between
the elbows. A support band (SPSB) is required at the upper elbow
of the pair to support the load, as shown in Figure 30. Attach the
upper elbow to bring the chimney back to vertical.
Offset combinations: see Table 5 and illustration, Figure 31.

FLASHING INSTALLATION
1. Continue the SP chimney to the roof. Cut the roof opening, cen-
tered over the chimney. A 2 inch-airspace around the chimney is
required as it penetrates the roof. The size of hole in the roof will
vary depending on the roof pitch.
2. Install the next SP chimney section through the roof. See Figure 32.
NOTE: If your roof is already shingled, be sure to slide the upper edge
under the shingles to prevent leakage.
3. Install a bead of caulk around the pipe at the top edge of the flash-
ing. Wrap the storm collar around the pipe and imbed the edge in
the caulk to prevent leakage around the pipe.
4. Continue to install pipe sections until the proper termination height
is reached. See termination section.
