TECHNICAL DATA
(1) Reference conditions: Room temperature 20°C - Gas temperature 15°C - Barometric pressure 1013 mbar - Altitude 0m above sea level.
(2) Socket pressure 7)(A)p.3 with zero pressure in the combustion chamber.
(3) Sound pressure measured in the manufacturer's combustion laboratory, with burner operating on the test boiler at maximum output and measured from one metre
away and at a frequency of 50Hz.
ACCESSORIES
(optional):
• KIT LONG HEAD
• KIT FOR LPG OPERATION:
the kit allows the RS 34-44/M MZ burners to burn LPG.
• KIT FOR MODULATING OPERATION
• GAS TRAINS TO COUPLE WITH THE BURNER, ACCORDING TO REGULATION EN 676 (complete with valves, pressure adjuster and
filter):
see page 8.
• POTENTIOMETER KIT FOR THE INDICATION OF LOAD POSITION:
