Non-conforming installs
Only use Dickinson Marine OEM
chimney parts for your install. The
use of some pipes, such as
aluminum or galvanized ducting (A)
is considered a safety hazard.
A barometric damper will operate
only on a vertically oriented pipe,
the damper cannot be mounted on
any kind of angle (B)
Elbows limit the chimneys ability to
develop and maintain a good draft.
Most of a chimney’s draft is
generated in its first 2-3 feet.
Having an elbow mounted within 2-
3 feet (C) will severely limit the
draft you’re able to achieve.
A.
90° bends in the chimney will
prevent it from venting
adequately (D) The 90° bends
baffle the exhaust gasses and
prevent them from rising and
creating a strong draft.
Chimney’s over 8 feet in
height may generate too
much draft and will unbalance
combustion inside the burner
(E) which may prevent it from
generating enough heat.
A barometric damper placed
too high on a chimney (F) will
not function as intended. For
best results place the
barometric damper within the
first 2 feet of chimney.

Double walled or insulated chimney
pipes are not compatible with Dickinson
chimney parts (G)
Altering the chimney diameter along its
run is not recommended (H) Each
appliance is designed to be supported
by the recommended chimney size.
Altering the chimney diameter can
affect its ability to draft unpredictably.
