2.1 Operating the Boiler
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 To shut down the boiler
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.
2.3 Frost Protection
1. The appliance incorporates a frost protection
thermostat that will light the appliance when it's
temperature falls to near freezing. Note that this is
designed to protect the boiler only - the system
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 *position (Fig. 3).
3. The frost protection will only operate if gas
and electrical supplies are switched on.
2.4 Central Heating System Pressure
1. The water pressure in the central heating
system is indicated by the pressure gauge.
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.

1. Your boiler is fitted with an additional safety
device which shuts down the appliance should the
system overheat. The "overheat" indicator light will
be illuminated if the appliance needs resetting.
NOTE: Any interruption to the electricity supply
may cause the device to operate. In the case of
persistent operation of the device, turn off the
boiler and consult your service engineer as an
appliance or system fault is indicated.
3.2 Resetting

2. Allow the boiler to cool if hot.
3. Hinge down the lower door panel (Fig. 7).

4.0 Clearances
6
4.1 Clearances around the boiler (Fig. 10)
1. The minimum clear spaces needed around the
boiler are:
Top: 50mm (2 in)
Bottom: 100mm (4 in)
Sides: 5mm (3/16 in)
Front: 5mm (3/16 in)
2. These clearances must not be obstructed in
any way. Blocking the clearance spaces will
result in the appliance overheating and possible
damage may occur.
3. The boiler may be installed in a cupboard if these
minimum clearances are kept. Note that the label
affixed to the front of the boiler must be left in place
to ensure future servicing is successfully
undertaken.
4. The compartment should be large enough to
house the boiler and ancillary equipment only.
5. IT SHOULD NOT BE USED AS A STORAGE
CUPBOARD.
6. The gas burning compartment of your boiler is
completely sealed from the room in which it is fitted.
Products from the combustion of gas are 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.
