General information 1
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 600 series provides central heating and
domestic hot water where a separate indirect hot water
cylinder is also incorporated to the system.
The benchmark gas boiler commissioning checklist (in
the installation manual) should be completed by the
installer and/or the commissioning engineer.
All CORGI Registered Installers carry a CORGI ID card,
and have a registration number. Both should be recorded
in the Benchmark gas boiler commissioning checklist.
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.

Vaillant ecoMAX appliances are made to fulfil the latest

These appliances are designed as boilers for use in central heating and hot water supply systems.

The purpose of EC designation is to certify that the boiler complies with the requirements of the directives
covering gasfired appliances (Council directive
90/396/EEC) and electromagnetic compatibility (Council
directive 89/336/EEC).
These appliances also comply with the requirements of
the directive on operating efficiency (Council directive
