IMPORTANT
To prevent possible recirculation of flue
gases, the installer must consider the
effects of prevailing wind conditions,
eddy zones, nearby buildings,
obstructions, or other obstacles such as
shrubs when planning exhaust and air
intake locations. M&G DuraVent can not
be held responsible for poor appliance
performance or damage to buildings
due to an incorrect installation. The
minimum clearances detailed within our
instructions may not be adequate in some
circumstances depending on the specifics
of the installation. For this reason we
always recommend vertical venting.
JOINT CONNECTIONS
Verify the gasket is seated evenly inside the
groove in the female end. There are two
versions of locking band available, one with
standoff legs (Fig.2), one without (Fig.3).
For both: Slide Locking Band on male pipe
section. Fig.2: For pipe without Locking
Button: Slide pipe sections together until
joint is bottomed out then slide apart ¼”
to 5/8” (7.5 - 15 mm) for expansion. Clip the
locking band clasp onto the female hub.
Fig.3: For PP/Metal pipe with Locking Button:
Insert locking button into locking band
recess, rotate button away from Locking
Band Clasp, insert pipe sections, push
lock band clamp downward into socket,
disengage button 1/4" from socket. Screws
are not allowed for joint connection.
Never penetrate the wall of PolyPro vent
pipe. (Exception- a SS screw may be
used outside the building on exterior
termination fittings to orient an elbow,
etc).
