Safety
Mechanical room conditions
Prevent the air from becoming contaminated by homogenate
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.
For the main, currently known sources refer to “sources
of combustion and ventilation air contaminants”.
Avoid continuously high levels of humidity (e.g. through
frequent drying of laundry).
Never close existing ventilation openings.
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 be a
qualified heating contractor.
WARNING
Incorrect ambient conditions can lead to damage to the
heating system and put safe operation at risk.
WARNING
The boiler must not be located in areas or rooms where
chemicals are stored, or aggressive vapors (i.e. bleach,
hair spray, methyl chloride, carbon tetrachloride or
perchloroethylene) or high dust levels or humidity levels
are present. Heat exchanger corrosion might occur and
reduce the lifetime of the boiler significantly. If above
criteria are not properly observed and boiler damage
results, any warranty on the complete boiler and related
components will be null and void.
