Requirements For Chimneys, Flues And Other Boiler Parts During Operation With; Chimneys; Flue Way - Atmos CP85KS Operation And Maintenance Manual

5. Requirements for chimneys, flues and other boiler parts
during operation with pneumatic burner cleaner

Chimneys

All requirements are identical to the requirements detailed in the boiler operation manual.

Flue way

Principle requirements are identical to the requirements detailed in the boiler operation manual.
You should be aware, however, that during pneumatic cleaning of the burner, expansion of compressed
air takes place in the burner and boiler combustion chamber. As such, you need to secure the flue
from falling out of the chimney and falling from the boiler neck. The flue must be mechanically
affixed to the boiler neck with a pin or screw. Similarly, other parts such as elbows or extensions
should be carefully secured to each other at joints.
You should also ensure that ash and dust is not blown out of flue joints between the boiler and
chimney during pneumatic cleaning. As such, all joints and flue outlets should be tightened with an
aluminium strip, putty or other similar method.
Securing the flue with a screw
WARNING – When using draught limiter placed on the flue way between the boiler and
the chimney is not permitted to use the type for the open double flap out of the flue way
(explosive type) because of possible dusting into the boiler room. If required, install draught
limiter into the cleaning hole at the foot of the chimney.
