BENCHMARK STANDARD
It confirms that the boiler has been installed and commissioned according to the manufacturers
instructions.
The log book provides space for the recording of regular servicing of the boiler/system and this can
become a valuable document when, for example, the householder wishes to sell the property. The log
book will show a potential purchaser that the heating system has received regular professional
attention during its lifetime.
The Benchmark initiative aims to:
Raise standards among professional installers
•
Build and maintain high safety standards in the industry
•
Improve customer satisfaction levels
•
Make a contribution to the nation's commitment to "Climate Change"
•

The Benchmark initiative is a code of practice to encourage the correct
installation, commissioning and servicing of domestic central heating
boilers and system equipment.
A "log book" is dispatched with every boiler. This is a vital document
that needs to be completed by the installer at the time of installation.

Questions and answers
I can’t get my green star I to stay operating it keeps turning off
The Worcester Greenstar i System boiler may keep turning off due to several possible reasons:
1. No Power – Check if the boiler has a permanent mains supply. Inspect Fuse F1 (2.5A) or Fuse F3 (0.5A) and the transformer. If faulty, replace the control board.
2. No Live Demand – Ensure there is a live demand at ST10-L from an external room thermostat or timer. Some older thermostats may not return proper voltage.
3. Diverter Valve Issue – If the boiler operates without a live demand signal, check that no permanent live feed is present at ST10-L from another source.
4. Incorrect Piping – Ensure the cold inlet and DHW outlet are correctly piped and not crossed.
5. Flow Turbine Issue – If the boiler is not operating during hot water demand, test the flow turbine.
Further troubleshooting may require checking the control board and other electrical components.
