aDDItIonal InStruCtIonS For
tErmInatIon
M&G Duravent's PP Flex terminations are
specifically designed for use with high-
efficiency appliances that are known to
produce high volumes of fluid due to
condensation of moisture within flue gases.
DO NOT modify these terminations.
IMPORTANT: Unless the appliance is designed
to address flow of condensates from the
vent system, a drain must be incorporated
within the vent to allow condensates and
rainwater to escape. This drain must include
a trap to prevent combustion gases from
entering living spaces. Be sure to check
the appliance manufacturer's installation
instructions closely in regards to condensate
management.
InStallatIon oF FlEx gaSKEt:
PP Flex pipe must always have gaskets
installed on both ends of any installation.
Gaskets are installed on the flex pipe, with the
gasket seating inside the flex pipe grooves
(Fig.1). Use soapy water to assist installation.
1. Cut PP flex pipe (knife, saw, etc) to
desired length. Special care should be taken
to ensure cut is square, and the edge is
deburred.
2. Place Flex Gasket over Flex pipe and install
in the first whole groove nearest the end.
3. Open the locking tabs (x2) of the
appropriate flex fitting to accept the flex pipe
(Fig.2)
4. Apply soapy water to the gasket, and push
pipe/gasket into appropriate flex fitting,
seating pipe down until it bottoms out
(Fig.2).
