1 General information

1.1 For your information

Thank you for choosing a Vaillant boiler. The information

given in this booklet will enable you to obtain the best

performance from your boiler.

ecoMAX 800 series provides both central heating and

domestic hot water, with the domestic hot water

supplied directly from the boiler. The boiler will operate

automatically to provide domestic hot water whenever a

hot water tap is opened, and automatically adjusts to

meet the demand for both central heating and domestic

hot water in the most economical way.

ecoMAX 600 series provides central heating and

domestic hot water where a separate indirect hot water

cylinder is also incorporated to the system.

The benchmark logbook should be completed by the

installer and/or the commissioning engineer and handed

to the user.

All CORGI Registered Installers carry a CORGI ID card,

and have a registration number.

Both should be recorded in your Benchmark Log Book.

You can check your installer by calling CORGI direct on

01256 372300.

If, after reading these instructions, you have any

questions on the operation of the boiler, please contact

either your installer or Vaillant Technical Department.
