rotate 360-degrees to allow elbows to point
in the desired direction. The PolyPro vent
pipe lengths may be cut to achieve specic
lengths. Alternatively, an Adjustable Pipe
adjusted or malfunctioning appliance
can deposit soot and other debris which
can enter the vent system. Any such
accumulation should be removed and the
appliances adjusted to eliminate future
accumulation. Use only a soft brush for
cleaning the sections and ttings. If any
leakage is found at joints the connected
appliances should be turned o and the
leaks repaired. A venting system must
not be routed into, through, or within any
other vent, such as an existing masonry or
factory-built chimney ue, unless that vent
or chimney is not being used to vent another
appliance and is only used as a conduit for
the gas-vent system.
Plastic venting systems shall not pass
through re rated separations.
JOINT CONNECTIONS
M&G DuraVent’s PolyPro vent is connected
together by slipping the male pipe end into
the female end (Figure 1) with about 2"
(50mm) of overlap. PolyPro vent products
have gaskets installed in the female pipe
ends. Before connecting the vent pipe
sections or components, verify the gasket
is seated evenly inside the groove in the
female end. The PolyPro joint section can

length that slips into the previous vent
pipe section is also available. Screws are
not allowed for joint connection. Never
penetrate the wall of PolyPro vent pipe
sections.
A Locking Band is required at every exhaust
vent joint, and optional for the air inlet vent
joints. To attach the Locking Band, slide it
over the male end of the pipe with the hook
and leg facing the joint. Push the male and
female ends together as described in these
instructions, and snap the hook in place over
the ared female end. To release the Locking
Band, pry the hook up. If the Locking Band
is installed at a joint where the Wall Strap
is used, align the Locking Band's hook with
the gap of the Wall Strap. The Locking Band
meets ULC S636 requirements for securing
the joint. In addition, supporting Wall Straps
are required at least every 10 feet (3 meters)
for vertical vent pipe sections, and horizontal
or sloped sections of vent pipe require one
supporting Wall Strap for each pipe section.
(Figure 2).
There are two options for Wall Straps: the
polypropylene snap-clamp style, and the
metal bolt-clamp style. (Figure 2, 3A & 3B)
Both options are approved and listed for
use with PolyPro. The polypropylene Wall
Strap can be attached at either the female
end of the pipe or on the body of the vent
pipe. Determine the location where the Wall
Strap’s anchor bolt will mount into the wall
