Straight Vent Pipe
(through ceiling and roof)
*Use only MullToa Vent Pipe. Installing other vent pipe can cause venting problems and odours.*
1.
Position the toilet against the wall.
2.
Drill a 2 1/4” (55mm) hole in the ceiling above the vent connection in the toilet (use Plumb Bob to align vent
pipe with toilet).
3.
Drill a 2 1/4” (55mm) hole in the roof above the hole in the ceiling.
4.
Insert 1 length of white pipe (belled end up) into the rubber vent opening on the back of the toilet.
5.
Continue adding white ventilation pipe, belled end up, through the holes and seal with silicone around the
hole and roof to avoid any leakage.
6.
The white pipe must extend through the
roof, by approximately 2”.
IMPORTANT:
All pipe from ceiling through
any unheated area (i.e. attic space) it must be
insulated. Ensure there are no gaps in
insulation. Use Only MullToa Attic Pipe &
Insulation (additional pieces sold separately).
7.
Insulate the pipe in the area between the
ceiling and the roof. Insulate the pipe
above the roof.
8.
Cut the non-belled black pipe and
insulation to match the angle of the roof.
9.
Slide roof flashing over non-belled black
pipe.
10.
Outline the Flashing on the roof. Raise
Flashing and apply silicone inside the
outline of the flashing.
11.
Slide the Flashing back down, sliding the
flange under the shingles along the top
edge and press it firmly into the silicone.
When flashing is properly placed, the top
part of the flashing should be under the
shingles and the lower portion should be
on top so water sheds easily.
12.
Secure the top of the flashing with corrosion resistant nails or staples at each corner and along the sides at
4” – 6” intervals. Exposed nails or staples should be sealed with silicone.
13.
Attach additional pieces of black pipe, insulation and white pipe.
14.
The end of the last pipe must extend a minimum of 50cm (19.5”) above the peak of the roof or anything
within 10 feet.
15.
Fit the Reducing Coupling down onto the last black pipe.
16.
Attach Insect Netting (optional). In winter (extremely cold areas) icing up can occur and removal of netting
may be necessary.
