2.0 Operating the Boiler
4
2.1 Operating the Boiler
1. Remove the lower door panel by gripping it’s
lower edge and rotating upwards (Fig. 1).
2. Turn on the main gas and electricity supplies
to the appliance.
3. Set the boiler thermostat control knob to the
required setting (Fig. 3). (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. 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 on. Mains ON is indicated
by green and boiler ON by yellow (Fig. 2).
5. Flashing mains ON light indicates that there is
a mains electrical supply to the boiler, but the
control knob is in the OFF position. Turn the
control knob on and ignition will start.
2.2 To shut down the Boiler
1. Turn off the electricity supply to the appliance
at the mains.
2. Turn the boiler thermostat control knob to OFF
““(Fig. 4), then turn off the gas supply at either
the appliance gas cock or the meter.
2.3 Frost Protection
1. The boiler does not have integral frost
protection. It is recommended that the installer
fits a suitable protection device to the system
controls if required. For frost protection the boiler
must be turned on.
2.4 In Operation
1. The 100 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 steam 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
appliance in any way.

4.1 Clearances around the Boiler
(Figs. 8 & 9)
1. The minimum clear spaces needed around
the boiler are:
Top - 200mm
Bottom - 50mm
Both sides - 5mm
Front - 500mm (For Servicing)

vented to the outside through the flue terminal
which must be kept free from obstruction as this
would interfere with the correct operation of the
boiler.
