CHAPTER 15
CHIMNEY AND FLUE
Chimney
Principles
The principle of the chimney is to discharge smoke from the flue into
the atmosphere.
Maintenance
Make sure the chimney and chimney extension(s) are clean and in
good condition.
The chimney may be cleaned from the top with a chimney-cleaning
device. Inspect the chimney twice a month during the heating
season to ensure there is not an excessive amount of creosote. If an
excessive creosote buildup has occured, it must be removed promptly
to reduce the risk of a chimney fire.
When the unit is shut down for the summer, inspect and clean the chimney for the next heating season. When
the furnace is not in use, cover the chimney so nothing can enter.
DO NOT connect to a chimney flue serving another appliance.
Chimney Extension(s)
Principles
Chimney extensions discharge smoke higher into the atmosphere. They also discharge sparks higher into the
atmosphere, so they have more chance of being burned out before the reach the ground. Aproved chimney
extensions may be added to the chimney to discharge smoke to higher levels. Discharging smoke at a higher
level helps keep smoke above property level, especially on low pressure or cloudy, hazy or wet days. When
installing chimney extensions, you must have no less than three tech-12 self tapping screws per extension.
Any chimney extension excedding 10 feet must be supported with guide wires.
There is one small extension holder that is specifically made for the model 400-4S. The design of that
extension holder acts as a draft damper and must be installed on the unit.
Please refer to the “Best Burn Practices” located on the inside front cover of this Operations and Maintenance
Manual.
Maintenance/Result
1) See chimney maintenance above.
2) Purchase approved chimney extensions that fit together correctly. If the extensions don’t fit properly,
they may fall off and cause a hazard.
3) Annually remove chimney extensions for cleaning and safety purposes.
In case of chimney fire, shut off combustion fan switch and consult your dealer. 10 inch steel extensions are
available from your local dealer.
NOTE: If more than one extension (more than 3 feet) is used on the model 400-4S, use all insulated steel
extensions after 3 feet. Insulated extensions are also available from your local dealer.
