2.0 Operating the Boiler

2.1
1. Hinge down the lower door panel as shown
(Fig. 1).
2. Turn the boiler thermostat knob fully anti-
clockwise to the '0' position (Fig. 3).
3. Turn on the main gas and electricity supplies to
the appliance.
4. Set the thermostat control knob to the required
setting. (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.)
5. The fan will start to run and after a short period
the ignition spark will commence. Sparking will
continue until the pilot flame is established then
stop automatically. The main gas will then come
on and the burner will light from the pilot flame.
The bottom four indicator lights should be
illuminated (Fig. 2).
2.2
1. Turn off the electricity supply to the appliance at
the mains.
2. Turn the thermostat knob to zero (Fig. 3) then
turn off the gas supply at either the appliance gas
cock or the meter.

1. The appliance incorporates a frost protection
thermostat that will light the appliance when it's

pipework may require the protection of an
additional frost thermostat.
2. To set the appliance to frost protection but
without normal heating. Turn the control knob to
the *
3. The frost protection will only operate if gas
and electrical supplies are switched on.
2.4
1. The water pressure in the central heating
system is indicated by the pressure gauge.
3
2. The normal operating pressure is the range
between 1 and 2.5 (Fig. 4).
3. A pressure of 3 or greater indicates a fault. The
safety pressure relief valve will operate at a
pressure of 3 (Fig. 5). It is important that your
Service Engineer is contacted as soon as
possible.
4. The MINIMUM pressure for correct operation
is 1.
5. If the pressure falls below 1, this may indicate a
leak on the central heating system (Fig. 6).
6. The system must be re-pressurised by your
Service Engineer.
