4 Openings for combustion air
supply and venting
Caution: Risk of boiler damage and mal-
functions due to missing or inadequate open-
ings for combustion air and venting of the
boiler room.
The openings for combustion air supply and
venting are always required regardless of
whether the combustion air is drawn from the
room (conventional flue) or supplied directly
to the boiler through ducts (balanced flue).
Inadequate venting of the boiler room
may result in excessive ambient tem-
peratures. This can damage the boiler.
Inadequate combustion air supply may
cause malfunctions in operation.
• Make sure that air inlet or outlet vents are
not closed off or their size reduced and
that they are adequately dimensioned.
• The boiler must not be operated until the
obstruction has been removed.
• Draw the operator's attention to any defi-
ciencies and the potential dangers.
Caution: Risk of boiler damage from con-
taminated combustion air.
• Never use cleaning agents that contain
chlorine or halogenated hydrocarbons
(e.g. in spray cans, solvents and cleaning
agents, paints, glues).
• Do not store or use such substances in
the boiler room.
• Avoid excessive dust accumulation.
If impurities in the combustion air are possi-
ble (e.g. installation near swimming pools, dry
cleaners or hairdressing salons), operation
independent of room air is recommended.
Caution: Dangers posed by explosive and
easily combustible materials.
• Do not use or store easily combustible ma-
terials (paper, lace curtains, clothing, thin-
ners, paints, etc.) near the boiler.
• Maintain a clearance of 16 inches from the
boiler.
