The combustion air intake grille should be located in a well ventilated place. To prevent corrosion, the
c
ombustion air must be free of aggressive substances. Aggressive substances are halogenated
hydrocarbons that contain chlorine or fluorine. These substances are found in solvents, paints,
adhesives, gases or liquid propellants and household cleaners. If these conditions cannot be
guaranteed, another location should be chosen for the air intake.
