GENERAL

The following instructions are given for the guidance of the operator in the use of the RB/RBC
series gas fired steam boiler and to provide adequate information to ensure that when the boiler
is put into use it will be done safely and without risk to health. Where original equipment service
manuals are supplied, they must be read and understood in conjunction with this manual.
All warnings and cautions must be observed.
3.2

CONTROLS

The following brief description of the controls used on the RB/RBC series fuel fired steam boiler is
intended to provide the operator with a basic understanding of the operating principles, which is
essential for the continued efficient operation of the boiler.
3.2.1

SYSTEM CONTROLS

Low Water Safety Relays and Feedwater Pump Relays
These relays operate in conjunction with probes suspended in the boiler shell to automatically
maintain the water level in the boiler between set limits.
If the water should fall to an unsafe level, the burner is cut out and an alarm is sounded.
The probes are located in two, 100 mm diameter standpipe flanges mounted on either side of the
boiler center line towards the front of the boiler.
A standard boiler is fitted with Feedwater Pump On/Off, 1st Low Water and 2nd Low Water
probes.
A 15 mm TDS (surface) Blowdown connection is supplied, fitted with a blank flange.
If a TDS monitored system is fitted it should be interlocked such that the valve will not open when
the feedwater pump is running.
Steam Pressure Control(s). Located on the control panel box and connected to the steam
pressure gauge by copper tube, the pressure regulator controls the on/off cycle of the burner,
shutting the burner off when maximum pressure is reached and switching it on when the steam
pressure falls.
