Exterior Chimney - Osburn 2200 Owner's Manual

1.5.3.3

Exterior Chimney

Chimneys constructed outside of the home on an exterior wall should be avoided if possible,
especially in colder climates. Exterior chimneys may not draft well and in fact may down draft
(reverse flow) due to the difficulty in heating them up to operating temperature while trying to
evacuate the stack gases. All else being equal, cooler chimneys will have less draft than hotter
ones; this may lead to creosoting and poor performance. If an exterior chimney is used to remove
the stack gases the best results will be obtained by using a connector vertically off the unit to the
highest possible point before elbowing off horizontally to the chimney. For efficiency and safety
reasons the stove be installed with an insulated chimney connected directly to the
must not
appliance.
