OPERATION - 3
Do not attempt to start the boiler until this section has been read and fully understood. Carry out
the following procedure on the initial start up of the boiler and on every subsequent occasion
when restarting the boiler after a shut-down.
1. OPEN the steam valve.
2. OPEN all the valves in the feedwater line. Ensure the feedwater pump is primed.
3. Switch the door isolator switch to the ON position.
4. With the boiler selector switch ON
and the boiler and tank elements (when fitted)
ON. Turn
the Feedwater Pump On/Off switch to the OFF position. Open the boiler blowdown valve and
lower the water level in the boiler until the Low Water Alarm Reset button is illuminated and the
alarm sounds.
Note: When the Low Water Level alarm sounds, elements that are energised should de-energise and the
Element Switches should extinguish.
5. CLOSE the blowdown valve. Turn the Feedwater Pump On/Off switch to the ON position. The
feedwater pump should start and restore the water level to the normal position and stop.
6. Press the Low Water Level Reset button. The light should extinguish and the audible alarm
should cease. The elements should re-energise, the Element Switches should illuminate.
The boiler is now ready for use.
The on/off steam pressure controller will control the on/off cycle of the elements once the boiler
is operating. The low water relays automatically maintain the level of water in the boiler (and tank
if fitted) and will immediately shut off the power to the elements should the water level fall to an
unsafe level. The Element Switches situated on the control panel enable elements to be switched
on or off independently to meet steam requirements.
