VERTICAL FLUE EXTENSION KIT (APPROVED MODELS)
maximum of 6.1 m.
The inner and outer pipes may be cut if only a
(PART # 946-756)
short length is required.
2. Install spring spacers around 127 mm inner pipe as shown. Slide
outer flex pipe over and all the way down the 127 mm pipe.
3. Apply a bead of Mill Pac around the perimeter of the 127 mm
inner collar of the flex adapter and slip the 127 mm inner flex
pipe from the Vertical termination kit over the flex adapter ensur-
ing that the inner flex pipe overlaps the collar by at least 35 mm.
Fasten with 3 screws.
4. Apply a bead of Mill Pac around the perimeter of the 203 mm
outer collar of the flue adapter and slip it over the 203 mm outer
flex pipe from the vertical termination kit ensuring that the outer
flex pipe overlaps the collar by at least 35 mm. Fasten with the 3
screws.
5. Repeat steps to secure the other end of the flex adapter using
the flex kit.
6. See vertical vent installation instructions for installation of the
complete vent system.
If an offset is necessary in the attic or floor joists
it is important to sup-port the vent pipe every 0.91
m to avoid excessive stress and sagging of the
vent pipe. Wall straps are provided (3 in total) for
this purpose.
All round/plumbers strapping may also be used if
further supports are required.
