breaching. When chimneys are of an unusual height
or if the draE to be maintained is either very high or
very low, it is advisable to deviate from the rules of
thumb outlined here. Refer to the larger table

Warm outside temperatures will result in
decreased draE. /is can lead to operational
concerns related to poor draE. Changes may be
needed when transitioning between seasons and
warm outside temperatures result in poor draE, or
vice versa, when cold outdoor temperatures result in
increased draE. It sometimes necessary to add a
draE inducer in warmer seasons to maintain the
recommended -.04 to -.08 inches of water column.
/e air@ow through the system and out the
chimney means that oxygen is leaving the home and
will create an oxygen de1cit if this air is not
replaced. /ere is usually suIcient leakage in older
homes, but in well-insulated homes it may be
necessary to provide additional outside air into the
home.
Stovepipe
Use only 22-24 gauge single wall stove pipe in
open areas that are no closer than 18 inches from
walls or ceiling. If the stovepipe must be closer than
18 inches from the nearest wall or ceiling, or if it
must go through walls, closets, or boxed in areas,
then UL listed insulated stovepipe must be used.
Stovepipe that runs along the outside walls of a
building must also be UL listed insulated pipe, even
if it runs along a non-combustible outside wall. /is
requirement is in place in order to prevent cooling of
the stovepipe, which in turn cools the rising smoke
and causes creosote to form quickly (however, this
provision does not apply to the Coal Gun because
there is not suIcient gas generated in the exhaust to
cause creosote).
Proper Chimney Connection
/e boiler must be connected to a listed type HT
prefabricated or masonry chimney. For connecting
pipe, 24 gauge black or blued or stainless steel is the
minimum requirement. Stainless steel is
recommended for durability, preferably 300 series

The airflow through the system and
out the chimney means that oxygen
is leaving the home and will create
an oxygen deficit if this air is not
replaced.
Note: Manually operated dampers must not be
used with the Coal Gun
