VENTING: APPROVED MATERIALS
The Ashby requires a venting system approved for pellet or corn venting by a certified testing
lab. Approved pellet or corn venting materials are: 1) PL vent, a double wall vent with a stainless
steel liner; and 2) Single wall rigid or flexible stainless steel pipe. PL Vent and Single wall vent
is available through manufacturers such as: Energy Vent LTD, James A. Ryder, Simpson
DuraVent and Selkirk Metalbestos and is carried by many local dealers. In this manual approved
venting will be referred to a “PL vent” or “Single wall vent”. All single wall vent adaptors must
be stainless steel.
NOTE: TYPE “B” GAS VENT MUST NOT BE USED IN THE INSTALLATION OF THE
ASHBY-P INSERT
Examples of venting system components follow:
High temperature ceramic roping reduces potential fly ash escaping through joints.
Stainless steel inner liners resist corrosive flue gas damage to the system.
Flex pipe should be stainless steel, 4 ply construction with a total thickness of approximately .07
inches.
