Fresh air inlet

Fresh air inlet for operation independent of ambient air

Due to the robust design of the burners, a fresh air inlet is not required for common applications under normal operating conditions. You can install the device with fresh air inlet only if the device is operated in rooms exposed to extreme loads (e.g. due to chemicals or welding dust) or in rooms with ventilation or bleeding systems (see figure). Individual or combined exhaust gas systems can be operated independent of ambient air.
