5.1

GENERAL

The following instructions are given for the guidance of the competent operator in the use of the
VSRT fuel 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.
5.2

CONTROLS

The following description of the controls used on the VSRT 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.
5.2.1

BOILER CONTROLS

Note: All the limiters are of the 'fail-safe' type and are wired in series; failure of any one will automatically shut
down the boiler.
Low Water Limiters, Feedwater Pump and High Water Level Controller
These limiters and controller operate in conjunction with probes suspended in the boiler to
automatically maintain the level of water in the boiler and to cut off the burner should the water
level fall to an unsafe level.
Steam Pressure Control(s)
Located on a bracket above the control panel box and connected to the steam pressure gauge
assembly by copper tube, the pressure transducer controls the modulation of the burner,
shutting the burner off when maximum operating pressure is reached and switching it on when
the steam pressure falls.
Burner Programmer
This is the main control inside the panel box. The programmer in conjunction with a sensing
device 'supervises' the ignition sequence, proves the flame is satisfactory and finally 'monitors'
the established flame. Should any fault occur, either during the ignition sequence or during normal
running, the programmer will immediately go to 'lockout' and the Multi-bloc gas valve will be
closed.
