GENERAL

The following instructions are given for the guidance of the operator in the use of the Series 'E' gas fired
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.

BOILER CONTROLS

The following brief description of the controls used on the Series E gas fired 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.
Note: All the controls are of the 'fail-safe' type and are wired in series; failure of any one will automatically
shut down the boiler.
Low Water Relays and Feedwater Pump Relays. These relays operate in conjunction with probes
suspended in the boiler and water column 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 the control panel box and connected to the steam pressure gauge
assembly 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.
Burner Programmer. This is the main control in 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 'lock-out' and both main and pilot gas valves
will be closed.
Air Pressure Switch. Mounted on the burner scroll, this switch is operated by the pressure of air entering
the burner through the throat of the scroll. Lack of air, or insufficient pressure, will prevent the switch
completing the circuit thus preventing the burner from operating.
Gas Head Assembly. Consists of pilot and main gas supply lines, each line having a manual gas cock,
a governor and electrically powered gas valves. The governors maintain a constant pressure of gas
entering the burner and are adjustable. The electrically powered gas valves are controlled by the
burner programmer.
