4.1 Central Heating System Pressure
1. The normal operating water pressure is between 1
and 2.5 bar (Fig. 1). If the pressure exceeds 3 bar the
safety pressure valve will operate and a fault is indicated
(E117 displayed). Contact your installer.
2. It may be necessary to repressurise the system
occasionally (as Fig. 2 or E118 displayed). A filling device
(the filling loop) will be fitted on the system. This will be
on the boiler itself, or on pipework near to the boiler.
3. If you are unsure of its position, or cannot identify it,
consult the installer who fitted the boiler.
4. The filling loop consists of two taps and a separate
copper pipe with connection fittings.
5. Only when repressurising should the copper pipe be
connected between the two taps. Ensure that the nuts
on the pipe ends are tightened onto the taps.
6. Fully open one of the taps first, and then while
watching the pressure gauge, carefully open the second
tap.
7. The system pressure is shown at all times on the
gauge under the boiler and can be viewed on the display
when there is power to the boiler.
8. To display the water pressure press 6 times. ‘05’
will alternate with the system pressure. (NOTE: When
the pump is running the gauge under the boiler may
show a slightly different reading to the display)
9. When the needle on the gauge or figures on the
display indicate 1 or more turn both taps off.
10. Disconnect the copper pipe from the taps (a small
amount of water may be present) and remove it. Keep
the pipe in a safe place for future use.
4.2 ‘Service Due’ Message
1. After 11 months operation the ‘Service Due’ message will
be shown on the boiler display.
2. Please contact your Installer, Annual Service Provider or
Baxi Customer Support on 0344 871 1525 to arrange your
Annual Service.

5.0 Clearances
8© Baxi Heating UK Ltd 2015
5.1 For your Safety
1. This appliance must have been installed in accordance
with the manufacturer’s instructions and the regulations
in force.
2. Any modification that may interfere with the normal
operation of the appliance without express written
permission from the manufacturer or his agent could
invalidate the appliance warranty. In GB this could also
infringe the Gas Safety (Installation and Use) Regulations.
3. Your boiler must not be operated without the casing
correctly fitted.
4. Do not interfere with any sealed components on this
boiler.
5. Take note of any warning labels on your boiler.
6. Your boiler should have the following minimum
clearances for Safety and Maintenance
(Figs. 3 & 4):-
Top - 175mm
Bottom - 150mm*
Left side - 5mm
Right Side - 5mm
Front - 5mm (In Operation)
- 450mm (For Servicing)
*This is MINIMUM recommended dimension. Greater
clearance will aid installation and maintenance.
7. If your boiler is installed in a compartment, do not use
it for storage purposes. Do not obstruct any purpose
provided ventilation openings.
8. Flammable materials must not be stored in close
proximity to your boiler.
9. Avoid skin contact when your boiler is in operation, as
some surfaces may get hot e.g. pipework.
10. Ensure that the flue terminal, outside the house,
does not become damaged or obstructed, particularly
by foliage.
11. It is important that the condensate drain system is
not blocked, modified or damaged in any way as this
would affect the operation of your boiler. Your installer
should have insulated any exposed pipework.
