3.3 Environmental
conditions Caution
An open appliance may not be used in rooms where chemical substances
are stored or used due to the risk of explosion and corrosion of the appliance.
Some propellants, bleaching agents and degreasing agents etc. disperse
vapours that are explosive and/or cause accelerated corrosion. If the appliance
is used in a room in which such substances are present, the warranty will be
void.
The appliance is suitable for both open and closed combustion.
For closed combustion, the air supply required is independent of the room in
which it is installed. In this event, there are no additional ventilation
requirements. Appliance types possible here are C13 and C33.
The appliances can also be installed as open appliances and may then only
be placed in an open boiler room. The appliance type is B23.
3.3.1 Air humidity and ambient temperature
The boiler room must be frost-free, or be protected against frost. The table
shows the environmental conditions that must be adhered to for correct
