© Baxi Heating UK Ltd 2010
5.1 Cleaning the Outer case
The painted panels should be wiped with a damp cloth and
then dried completely. DO NOT USE ABRASIVE
CLEANING AGENTS.
5.2 Protection & Precaution
1. The boiler incorporates an integral frost protection feature
that will operate when the selector switch is in the ( )
position. If the boiler temperature falls below 5° C, then the
boiler will operate until the water temperature has been
raised.
2. If a system frost thermostat has been fitted (your installer
will be able to advise you), then to operate correctly and
protect your system, the gas and electricity must be left on and
the appliance set in the central heating mode.
3. The boiler incorporates an integral pump protection feature
which continually monitors the time since the pump last
operated. To prevent seizure, the pump will operate for
approximately 1 minute if it has not run in the last 24 hours.
5.3 Fault Indication
1. If a fault occurs on the boiler an error code may be shown
on the facia display (Fig. 5).
2. The codes are either two or three digit, preceded by the
letter 'E'. For example, code E133 will be displayed by 'E1'
alternating with '33'. E50 is shown as 'E' then '50'.
3. E20, E28, E50, E125 & E160 indicate faulty components.
You should make a note of the displayed error code and
contact your installer or service engineer.
4. If E110 or E130 is displayed overheat of the primary water
or flue system has occurred. Turn the selector switch to the
reset position and hold for at least 5 seconds. If the boiler
does not relight, or the code is displayed regularly contact your
installer or service engineer.
5. E119 is displayed when the primary water pressure is less
than 0.5 bar. After repressurising the system the boiler should
operate. Your installer will be able to advise you about the
method of repressurising. See page 6 for further details.
6. E133 indicates that the gas supply has been interrupted,
ignition has failed or the flame has not been detected. Ensure
that the gas supply has not been turned off, and turn the
selector switch to the reset position and hold for at least 5
seconds. If the boiler does not relight, or the code is displayed
regularly contact your installer or service engineer.
