1.0 Operating the Boiler

1.1 Operating the Boiler
1. Hinge down the facia cover (Fig. 1).
2. Turn on the main gas and electricity supplies to the
boiler. The Mains On light ( ) will illuminate green
(Figs. 1 & 2).
3. Set the central heating control knob to the required
setting (Fig. 1). (The optimum boiler setting depends
upon type of system, external controls and your
requirements. Your installer will be able to advise you on
this matter.)
4. When the system control(s) call for heat the fan will
start to run and after a short period the ignition spark will
commence. Sparking will continue until the flame is
established then stop automatically. Check that both the
Mains ON light ( ) and Boiler ON light ( ) are
illuminated green (Figs. 1 & 2).
5. The boiler can be switched off by turning all external
controls or the optional integral timer Heating and Hot
Water settings to OFF.
1.2 To shut down the Boiler
1. Turn off the electricity supply to the boiler at the
system isolation switch and turn off all external controls.
2. Your installer should have demonstrated how to shut
down the boiler - if not he will be able to advise you.
1.3 Frost Protection
1. The boiler has integral frost protection. It is
recommended that the installer fits a suitable device to
also protect the system if required. The boiler must be
turned ON at the system isolation switch for frost
protection.
1.4 In Operation
1. The Promax FSB 30 HE is a high efficiency “condensing
boiler”. In common with other condensing boilers its
exceptional efficiency means the flue gases are cooled to
such an extent that a plume of water vapour is often
visible at the outside flue terminal. The amount produced
depends on system design, product use and outside air
temperature but it is not harmful to the individual or the
working of the boiler in any way.
2. The boiler incorporates a condensate pump which
may operate at any time, for up to 30 seconds, even
when the boiler is not running.
1.5 In the Event of a Gas Leak
1. If a gas leak occurs or is suspected, turn off the gas
supply at the meter control.
2. Do not operate electric light or power switches, either
off or on and ventilate the property.
3. Contact your gas supplier.
