Step 4.
Assemble the desired lengths of GS pipe and elbows necessary to reach from
the stove up through the round support box. Ensure that all pipe and elbow
connections are in their fully twist-locked position. Be sure to seal the outer pipe
with appropriate sealant (high temperature silicone).
Step 5.
Cut a hole in the roof centered on the small drill hole placed in the roof in Step 2.
The hole should be of sufficient size to meet the minimum requirements for
clearance to combustibles, as specified. Continue to assemble lengths of pipe
and elbows necessary to reach from the ceiling support box up through the roof
line. Galvanized pipe and elbows may be utilized in the attic, as well as above
the roofline. The galvanized finish is desirable above the roofline, due to its higher
corrosion resistance.
NOTE:
(1)
If an offset is necessary in the attic to avoid obstructions, it is important to sup-
port the vent pipe every 3' (914mm) to avoid excessive stress on the elbows, and
possible separation. Wall straps are available for this purpose (page 38, Figure
11).
(2)
Whenever possible, use 45° elbows, instead of 90° elbows. The 45° elbow of-
fers less restriction to the flow of flue gases and intake air.
Step 6.
Slip the flashing over the pipe section(s) protruding through the roof. Secure the
base of the flashing to the roof with roofing nails. Insure the roofing material
overlaps the top edge of the flashing as shown in Figure 14. Verify that the
chimney is the required height above the roof. See “2-10-3 Vertical Termination
Rule” on page 28 of this manual
Step 3.
To install the round support box/wall thimble in a flat ceiling, cut a 10" (254mm)
square hole in the ceiling, centered on the hole drilled in Step 2. Frame the hole
as shown in Figure 13.
