TECHNICAL DATA
(1) Reference conditions: Ambient temperature 68 °F (20 °C) - Barometric pressure 394” WC - Altitude 329 ft.
(2) Pressure at test point 8)(A)p.4, with zero pressure in the combustion chamber, with open gas ring 2)(B)p.8 at maximum burner output
(3) Sound pressure measured in manufacturer’s combustion laboratory, with burner operating on test boiler and at maximum rated output.

ACCESSORIES
(optional):
•
Kit for LPG operation:
The kit allows the RS 28-38-50/M burners to operate on LPG.
•
Modulating control kit:
Under modulating operation, the burner automatically adapts to one of an infinite number of firing rates between the low
and high flame output position, thus ensuring stable operating conditions in terms of temperature or pressure. Two components should be ordered: •
Modulating control to install to the burner; • probe to install to the boiler.
•
Gas train according to UL Standards:
see page 9.
• Kit for lengthening the combustion head
