TECHNICAL DATA
(1) Reference conditions: Ambient temperature 20°C - Barometric pressure 1000 mbar - Altitude 100 m a.s.l.
(2) Pressure at test point 8)(A)p.8, with zero pressure in the combustion chambre, with open gas ring 2)(B)p.16 an maximum burner output
(3) Sound pressure measured in manufacturers combustion laboratory, with burner operating on test boiler and at maximum rated output.
VARIANTS:
ACCESSORIES
(optional):
• KIT FOR LPG OPERATION:
The kit allows the RS 28-38-50/M burners to operate on LPG.
• VIBRATION REDUCTION KIT
•
OUTPUT POWER REGULATOR 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: • Power regulator to install to the burner; • probe to install to the boiler.
•
GAS TRAIN ACCORDING TO REGULATION EN 676 (with valves, pressure governor and filter):
see page 19.

OPERATION
• On-Off (1 stop min each 24 hours).
This burner is also fitted for the continuos operation, if it is equipped
with the control box LANDIS type LGK 16.333 A27 (interchangeable
with the burner control box Landis LFL 1.333).
• Progressive two-stage or modulating by kit (see ACCESSOIRES).
