For your information

Thank you for choosing the Vaillant turboMAX pro boiler.
The information given in this booklet will enable you to
obtain the best performance from your boiler. TurboMAX
pro 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. If, after reading these instructions,
you have any questions on the operation of the boiler,
please contact either your installer or Vaillant Technical
Department.
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.
