PELLETVENT PRO CAS
INSTALLATION
the Simpson Dura-Vent’s CAS system for
PelletVent Pro can be used for horizontal
(through-the-wall) installations; the CAS system
cannot be used with vertical (through-the-ceiling)
installations. the CAS system is designed to
connect to the stove’s air-inlet while still safely
venting the exhaust. figure 1 shows two typical
styles of installation using the CAS system for
PelletVent Pro, the first goes directly out the back
of the unit using the Wall thimble, the second
uses the Wall Channel and the Wall thimble for
when vertical rise is needed.
Step 1. locate both the air-inlet and the vent
exhaust outlet on the pellet-burning appliance.
the CAS system for PelletVent can only be
installed if your appliance has an air-inlet used
for combustion.
Step 2. Determine the location of the CAS
Wall thimble. the CAS Wall thimble should
be located between wall studs and to allow a
convenient connection for the air inlet of the
appliance. Avoid cutting wall studs if possible.
Depending on your installation, you may or
may not need to use the Adjustable Wall
Channel. the Adjustable Wall Channel is used
for installations where the wall penetration
is higher on the wall than the flex length
can reach. If using the CAS Adjustable Wall
Channel, position the CAS Wall thimble so
that the channel will be positioned directly
behind the appliance. If the CAS Adjustable
Wall Channel is not used, make sure the CAS
Wall thimble is positioned so the intake-air flex
can reach the air inlet of the appliance (Fig 1).
