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

Fused Spur.
2. Turn off the gas supply at either the appliance gas

2.3 Frost Protection

protection device to the system controls if required. For
frost protection the boiler must not be switched off at
the isolation switch on the wall.
2.4 In O eration
1. The 100/2 HE Plus 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.
