GENERAL INSTALLATION NOTES
Read these instructions before beginning.
You must use only authorized M&G DuraVent
PolyPro vent parts, or other parts specifically
authorized in these instructions and/or listed
by the appliance manufacturer in order to
maintain a safe, approved system.
•
Do not fill any air space clearance
(
Table 1
) with insulation.
•
Do not mix parts or try to match with
other products or use improvised
solutions.
•
Do not install damaged or modified
parts.
•

Never use Petroleum base lubricants.
If these directions and those of the appliance
manufacturer differ, follow the more
conservative requirements. If you have any
questions, contact either your dealer or M&G
DuraVent directly. A venting system must
not be routed into, through, or within any
other vent, such as an existing masonry or
factory-built chimney flue, 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 fire rated separations
without approved firestopping.
