Venting The Stove - Cumberland Stove Works MF3800 Installation And Service Manual

Venting the Pellet Stove:
• Do not install flue damper in the exhaust venting
system of this unit.
• Use an approved wall thimble when passing the vent
through walls. Use a ceiling support/fire stop spacer
when passing the vent through ceilings (make sure to
maintain clearance to any combustibles.)
• if using more than one tee and 180
use 4" venting pipes.
NOTE: To achieve optimum performance, it is recommended
that yo keep the vent as short as possible, especially in
regard to the horizontal run.
The vent must have a support bracket every 5' of pellet vent
when on the exterior of the structure.
The vent height and run must not exceed the distance as
illustrated in the diagram below.
Venting into this (the lighter) shaded area may require
combustion motor off-set adjustments. See "Fan Options"
on page 24 for more information.
