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
g
higher than 32° F / 0° C and
lower than 104° F / 40° C.
Prevent the air from becoming
g
contaminated by halogenated
hydrocarbons (e.g. as contained in
paint 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
g
humidity (e.g. through frequent
drying of laundry).
Never close existing ventilation
g
openings.
