Installation area conditions
WARNING
Incorrect ambient conditions can lead to
damage to the heating system and put
safe operation at risk.
Ensure ambient temperatures are higher
H
than 32°F / 0°C and lower than
104°F / 40°C.
Prevent the air from becoming
H
contaminated by halogenated
hydrocarbons (e.g. as contained in
paints solvents or cleaning fluids) and
excessive dust (e.g. through grinding or
polishing work).
Combustion air for the heating process,
and ventilation of the boiler room must
be free of corrosive contaminants. To
that end, any boiler must be installed in
an area that has no chemical exposure.
The list to the right indicates the main,
currently known sources.
Avoid continuously high levels of
H
humidity (e.g. through frequent drying of
laundry).
Never close existing ventilation
H
openings.
Replacement components, spare and wear
parts
IMPORTANT
Components which are not tested with
the heating system may damage the
heating system, or affect its functions.
Installation or replacement may only be
carried out by a qualified heating
contractor.
