WARNING
The boiler must be connected to an approved chimney in good condition. Serious property
damage could result if the boiler is connected to a dirty or inadequate chimney. The interior
of the chimney flue must be inspected and cleaned before the start of the heating season and
should be inspected periodically throughout the heating season for any obstructions. A clean
and unobstructed chimney flue is necessary to allow noxious fumes that could cause injury or
loss of life to vent safely and will contribute toward maintaining the boiler’s efficiency.
