SUPPLEMENT – VENTING INSTRUCTIONS FOR INSTALLATION AND OPERATING INSTRUCTION MANUALS

WARNING

The venting system must be properly installed. Failure to properly install the vent system could result in property
damage, personal injury, or death.

DO NOT install damaged venting system components. If damage is evident then please contact the supplier where
the water heater or venting system components were purchased for replacement parts.

Use only the vent terminals provided or factory authorized terminals for venting this water heater.

The water heater requires its own separate venting system. Do not connect the exhaust vent into an existing vent pipe
or chimney.

All of the exhaust venting connections must be leak checked with a soap solution upon initial start-up of the water
heater. Any leaks must be repaired before continuing operation of the water heater.

Do not terminate the venting where noise from the exhaust or intake will be objectionable. This includes locations
close to or across from windows and doors. Avoid anchoring the vent and intake pipes directly to framed walls, floors,
or ceilings unless rubber isolation pipe hangers are used. This prevents any vibrations from being transmitted into the
living spaces.

Do not exceed the venting distances or the number of elbows listed in the instruction manual supplied with the water
heater. Exceeding the maximum venting distances may cause the water heater to malfunction or cause an unsafe
condition.

DO NOT operate this water heater until the venting installation is complete and the piping completed. Failure to
complete installation before operation can result in property damage, personal injury, or death.

DO NOT install Duravent Polypro venting components with any other manufacturer’s vent components. Duravent
components must be used exclusively throughout the entire venting system from the water heater coupling or vent
connection to the outside wall or ceiling near the vent terminal location.

This supplement is intended only for additional information for installing Duravent Polypro single wall venting system
and the instruction manual supplied with the water heater must be followed for the detailed information provided for the
venting system installation.

INSTALLATION OF DURAVENT POLYPRO® SINGLE WALL POLYPROPYLENE VENTING SYSTEMS

This supplement is for the installation of polypropylene single wall venting system manufactured by M&G DuraVent, Inc.
The DuraVent Polypro venting system is a CSA approved alternative to the PVC, ABS, and CPVC venting components for
the High Efficiency Commercial Condensing, Commercial Power Direct Vent, Residential Power Direct Vent, Commercial
Power Vent and Residential Power Vent model series.

The DuraVent venting system components are ULC S636 approved and listed by a recognized agency and may be
installed in the U.S. and Canada. All components used must be from the same manufacturer and are designed for use
with the above noted products. The DuraVent components may be purchased from plumbing supply distributors. The
vent size diameter and maximum vent lengths must be followed as detailed in the Installation and Operating Instruction
Manual that was supplied with the water heater. Thoroughly read and understand the venting section of the instruction
manual supplied with the water heater before proceeding with the following instructions in this supplement. The vent
terminals supplied with the water heater or the factory approved accessory vent terminal kits must be used with this
venting system.

Step 1: Thoroughly read and understand the venting section of the Installation and Operating Instruction Manual that

WARNING

Use only water for lubricating the gaskets and pipe ends to allow easy insertion. DO NOT use any other kind of
lubricant, since deterioration of the gasket may result, which may allow dangerous flue gases to leak into the room.
If the vent pipe needs to be disassembled after the gasket has dried, wet the joint thoroughly to loosen the
connection.

was supplied with the water heater before determining the location of the water heater and the vent terminals. Locate
the water heater for the shortest practical vent length to the outside. Measure the total venting distance required to
reach the outside wall or roof. Determine the diameter of the venting components to use for the length of vent pipe
(and combustion air supply for direct vent models) required by referring to the venting tables in the instruction manual
for the maximum vent length for each diameter pipe size. Obtain all the necessary venting system components for the
installation.

Step 2: Before installation, inspect each vent component for damage making sure the gaskets for each component are
fully intact and in undamaged condition. Do not attempt to install or repair damaged components. If a gasket is
damaged, these are available from the supplier of DuraVent components. Do not use gaskets from another
manufacturer and do not try to repair the gasket.

Step 3: A DuraVent PVC to Polypropylene adapter (referred by DuraVent as Appliance Adapters, 2PPS-AD, 3PPS-AD, or
4PPS-AD) must be used to connect into a PVC coupling or tee (Commercial and Residential Power Direct Vent air intake
connections), condensate elbow (High Efficiency Commercial Condensing models) or the exhaust outlet adapter for
Commercial Power Vent and Residential Power Vent models. To make the insertion of the gasketed fittings into the
coupling easier, rotate the joints slightly and use water to lubricate the gaskets. DO NOT use any other kind of lubricant.

Wet the gasket surface and inside of the coupling using your finger or wet paper towel and insert the male end of the
adapter with the exterior gasket into the coupling, condensate elbow or exhaust outlet adapter connection. If a larger
vent diameter size is to be used, use the appropriately sized reducer coupling first on the water heater intake or exhaust
vent connection as detailed in the installation manual supplied with the water heater. See the following photos.

High Efficiency Condensing Commercial Models: Use the appropriate primer and cement (refer to venting section of
instruction manual with water heater) for cementing a PVC coupling (not supplied with water heater) to the end of the
PVC air intake pipe connection. Using your finger, wet with water the male gasketed end of the DuraVent PVC to
PolyPro adapter and fully insert into the air intake coupling. Loosen the DuraVent adapter connector clamp (PPS-PAC)
and install over the PVC coupling. See following photos.

DuraVent Adapter Connector Clamps (p/n: PPS-PAC) MUST be properly
installed to secure the PVC Vent Adapter. DO NOT operate the vent system
without first installing the Flue Adapter Connector Clamps.
