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

in the Benchmark gas boiler commissioning checklist. 
You can check your installer by calling CORGI direct on
