DuraVent PolyPro Flex Puller: an optional tool for guiding flex down a chimney
The DuraVent PolyPro Flex Puller is an optional tool for guiding a flexible liner down a masonry chimney from the roof. It comes with a rope to help guide the liner as it goes down. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters. Choose a 2, 3, 4, or 5 inch puller on this page. The 2 inch version snaps directly onto the flex. The larger sizes attach to the male flex adapter with a quarter turn to lock in place.
A qualified professional installs the PolyPro Flex liner, and the appliance manufacturer determines the allowed vent length. Flex carrying exhaust must stay inside a chimney or chase. It cannot run horizontally or bend more than 45 degrees away from vertical. Only flex supplying combustion air, the air used to burn the gas, can run outside an enclosure or on its side. Need the liner too? See the DuraVent PolyPro Flex Length flexible chimney liner. The DuraVent PolyPro Flex Puller ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
