INSTALLATION INSTRUCTIONS
31
Plan the layout of the vent system:
• Consider the length of horizontal runs,
elbows, clearance requirements, and location
of terminations.
• For horizontal vent runs, maintain at least
a ¼” rise per foot away from the appliance to
prevent collection of condensate or buildup of
heat in the vent.
• Consider condensate drainage, if needed
for your appliance. Refer to the appliance
manufacturer’s installation instructions for
requirements of condensate drainage.
• The CVS system must not be routed into,
through, or within any other vent or chimney,
with the exception of running the vent through
an otherwise unused masonry chimney.
• The vent system must terminate in
accordance with local code requirements and
appropriate National Codes:
o For the US (Gas): NFPA 54 / ANSI Z223.1
National Fuel Gas Code or the International
Fuel Gas Code
o For the US (Pellet): NFPA 211 Standard for
Chimneys, Fireplaces, Vents, and Solid Fuel
Burning Appliances
o For Canada: CAN/GGA-B149.1 Natural
Gas Installation Code or CAN/CGA-149.2
Propane Installation Code.
JOINT CONNECTIONS
M&G DuraVent’s Concentric Vent is connected
together by aligning the Alignment Dimples
on the male and female vent sections, sliding
together and twist locking in either direction
(Fig 1) . The joints will only connect and
come apart at the point where the Alignment
Dimples are aligned. The CVS joint section
can rotate 360-degrees to allow elbows to
point in the desired direction. The vent pipe
sections cannot be cut. Telescoping Adjustable
lengths are available to accommodate specific
installation length requirements. Screws are not required
for joint connection, except as where indicated for
Telescoping Adjustable lengths and Horizontal
Termination Caps.
APPLIANCE CONNECTION
Connect CVS vent pipe to the appliance adapter
Pensotti Part #: PA50-00137 via the DuraVent
Part #: 35CVS-AD-PS.
CONDENSATE DRAINS- GAS FUEL
CVS has an available Condensate Drain if
required by the appliance, and has a 5/8” ID
outlet which can be attached to an appropriate
size plastic tube for drainage. The Condensate
Drain can be used in either horizontal or
vertical orientation. When installing the
Condensate Drain, always create a siphon
loop in the plastic tube to prevent the leakage
of exhaust gases. Follow all local and national
codes for draining acidic condensate.
