DuraVent PolyPro Reline Hanger Support: holds flex liners beneath the chimney’s support plate
The DuraVent PolyPro Reline Hanger Support is a hanger that holds a flexible vent liner beneath a support plate at the chimney top. It lets two or more PolyPro Flex liners hang within the same chimney. A clamp wraps around the liner, and the hanger attaches to a support plate made for the job on site. A reline upper plate goes over the hanger. The same hanger fits 2 to 4 inch flex. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters.
The flexible liner does not attach directly to the appliance. Rigid PolyPro pipe carries the exhaust to the chimney base, where a male flex adapter joins it to the liner. At the top, a female flex adapter joins the liner back to rigid pipe. These adapters are fittings that connect the two pipe types. Plastic vent pipe must not pass through a fire rated wall or floor. DuraVent also recommends a vent inspection each year. Need the plate that covers the hanger? See the DuraVent PolyPro Reline Upper Plate cover. The DuraVent PolyPro Reline Hanger Support ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
