Combustion Air System
PelletVent Pro
The Combustion Air System (CAS) is a system designed to bring
in outside combustion air directly to your pellet stoves. This
eliminates the use of conditioned inside air for combustion,
improving the eciency of central heating systems.
Combustion Air System is a patent-pending design that pre-heats
combustion air. Inbound air is circulated through baes around
the heated areas of the support box or wall thimble. For PelletVent
Pro, the pre-heated air is delivered down a wall channel to assure
that the pellet vent is not cooled.
CAS enables outside air to be used as combustion air below
grade. The wall thimbles for both wood and pellet stoves provide
combustion air to appliances used in below grade (basement)
installations. Wood stoves utilize the triple wall stove pipe. Pellet
stoves utilize the adjustable air channel. CAS also minimizes down-
drafts in below grade installations. It does not consume warm
indoor air for combustion and not subject to oxygen starvation,
poor draft and other problems associated with ‘tight’ energy
ecient homes.
This system simplies installation with only one wall or ceiling
penetration, eliminating the need for a second penetration in
the building envelope to introduce combustion air. The design is
simple and elegant with decorative black nish. All products are
factory nished in matte black.
