Installation
■ Avoid air contamination through halogenated hydrocarbons (e.g. as
in sprays, paints, solvents and cleaning agents)
■ Avoid very dusty conditions
■ Avoid high levels of humidity
■ Prevent freezing and ensure good ventilation
Otherwise, the system may suffer faults and damage.
In rooms where air contamination through halogenated hydrocar-
bons may occur, install the boiler only if adequate measures can be
taken to provide a supply of uncontaminated combustion air.
