F. Assembly of DuraVent PolyPro Vent Systems
1. This boiler has been approved for use with the DuraVent PolyPro single wall PolyPropylene vent system to be provided by
the installer.
WARNING
Asphyxiation Hazard. Follow these instructions and the installation instructions included by the
original PolyPropylene venting component manufacturers, M&G/DuraVent. Failure to do so could
cause products of combustion to enter the building, resulting in severe property damage, personal
injury or death. Where a conflict arises between M&G/DuraVent instructions and these instructions,
the more restrictive instructions shall govern.
Do not mix vent components or joining methods for listed manufacturers.
Examine all components for possible shipping damage prior to installation.
All condensate that forms in the vent must be able to drain back to the boiler.
2. Assemble the vent system, starting at the boiler:
a. The vent adaptor has two different inside diameters. The smaller, lower, inside diameter accepts 3" nominal PolyPro
(Figure 7.26). Lubricate the upper gasket in the vent adaptor with soapy water and insert the first piece of 3" PolyPro into
the adaptor until it bottoms out. Tighten clamp on vent adapter to secure vent pipe.
b. If 2" PolyPro is to be used for the vent system, reduce the first piece of 3" PolyPro installed in Step (a) to 2" using
DuraVent #3PPS-R2. Otherwise assemble the next piece of 3" PolyPro.
c. For each joint, verify that the gasket is evenly seated in the bell (female) end of the pipe. Lubricate this gasket with water.
Slide a locking band over the male end of the pipe to be joined as shown in Figure 7.34. Push the male end of the next
section of pipe into the bell until it bottoms out, then back out 1/4-5/8" to provide room for thermal expansion. Push barb
on locking band over the bell end of the first section of pipe as shown in Figure 7.34.
d. Assemble the rest of the vent system per the manufacturer’s installation instructions, being sure to pitch horizontal
sections back towards the boiler 5/8" per ft.
e. Support each horizontal pipe section with a minimum of one wall strap each and at intervals not exceeding 4ft.
