EXHAUST VENTING
CONDENSATION: When planning the installation of your Corn stove, keep in mind that
condensation is detrimental to exhaust systems. Corn has higher moisture content than
pellets and can be more susceptible to condensation forming in certain types of
installations. Install the stove with a minimum of the system exposed to the cold
temperatures outside the envelope of the house. Check with the manufacturer of your
venting system that they honor the warranty of their PL Vent with the use of corn
.
VENTING: APPROVED MATERIALS
The stove requires a venting system, approved for pellet stoves by a certified testing lab.
Approved pellet stove 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 pellet stove 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 ANY CORN STOVE
INSTALLATION.
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 is 430 stainless steel, 4 ply construction with a total thickness of approx. .07 inches.
