Care and maintenance
Clean the outer casing of your boiler with a damp cloth
and a little soap. Do not use abrasive or solvent cleaning
agents that may damage the case or the plastic fittings.
The appliance should be serviced at least once per year.
To ensure regular servicing, it is strongly recommended
that arrangements are made with your service agent or
Vaillant Ltd. For further details please contact Vaillant
Service Solutions: 0870 6060777.
Frost protection
Your boiler is equipped with a frost protection function:
If the heating water temperature drops below 5 °C when
the main switch is ON, then the boiler goes into
operation and heats the boiler circuit to approx. 30 °C.
It cannot be guaranteed that water will circulate
throughout the entire heating system.
If the boiler is not operated for several hours during
very cold weather there is therefore the possibility of
the system freezing. Please ensure that if you are
absent during a period of frost the central heating
remains in operation and all rooms are kept above
freezing point.
It must be remembered, however, that the boiler will be
automatically switched off by the built in monitoring
devices if certain faults occur, e.g. interruption in the gas
or electricity supply or faults in the flue gas system. To
overcome this possibility you can drain both the central
heating system and boiler.
Frost protection and monitoring devices can
only function when the main switch of the unit
is set to the „I“ position and the boiler is
connected to the electrical supply.
Troubleshooting
In the unlikely event that a problem occurs with the
operation of the turboMAX pro combination boiler, the
following points should be checked:
1. Boiler fails to operate
• Is the gas supply turned on? (see page 4)
• Is the water supply turned on? (see page 4)
• Is there enough water in the heating system?
• Is the electrical supply switched on?
• Is the main ON/OFF control in the „On” position?
(switch position „I“)
• Is the burner lock out indicator light illuminated? (see
page 6)
2. Hot water operates but no central heating
• Is the heating turned ON? (see page 6).
• Are all external heating controls ON?
If your boiler still does not operate then please consult
your installer or Vaillant Service Solutions:
