Ceiling Support Box
Fresh air is drawn and warmed through
the top of the ceiling support box in the
attic. The air continues down an inner
chamber of the combustion air stove
pipe, and stubs out at the top of the
stove or tee. Aluminum flex completes
the connection to the appliance.
CAS system for DuraTech and DuraPlus HTC can
be used with both vertical (through-the ceiling)
and horizontal (through-the-wall) chimney
installations. DuraTech & DuraPlus HTC CAS
wood stove systems are available in 6” and 8”
chimney diameters, using system specic triple-
wall connector pipe, elbows, and tees to deliver
combustion air to the appliance from outside
the room through the chimney penetration,
eliminating the need for a separate penetration in
the structure for combustion air intake.
