The flanges can beturned through 90° or 180° in each case. Pressure measuring points ininlet and in outlet.Filter: Nylon wire gauze with chopped-strands mat fleeceSolenoid valves (T. A):Closing time: < 1 sSwitching frequency:anyDuty factor: 100% DFDegree of protection:IP 54 to IEC 529Adjustable gas pressure switch(only on version KE 15)The gas pressure monitor serves to monitor the gas in-let pressure. The burner is shut down if the gas inletpressure drops below the set minimum value (presetat factory to 12 mbar).
