A Keston magnetic system filter protects your boiler by capturing sludge, debris, and magnetic contaminants from the heating system. Installing a Keston 22mm System Filter with a Combi or System boiler extends the warranty from 5 to 7 years. The filter should be cleaned during annual servicing. It is fitted on the return pipe close to the boiler.

What is the Benchmark commissioning checklist for Keston boilers?

The Benchmark commissioning checklist is a document completed by your Gas Safe registered installer when commissioning your Keston boiler. It confirms the boiler has been installed correctly according to manufacturer guidelines and Building Regulations. The completed checklist should be left with the boiler and is required for warranty validation. Keep it safe with your boiler documentation.

Can a Keston boiler be installed in a cupboard or enclosed space?

Keston boilers can be installed in cupboards or enclosed spaces provided there is adequate ventilation and access for servicing. The boiler requires clearance around it for maintenance. Room-sealed boilers take combustion air from outside via the flue, so the cupboard does not need air vents. Always consult a Gas Safe registered engineer for installation requirements.

How do I repressurise my Keston boiler?

Turn off the boiler and allow it to cool for at least an hour. Locate the external filling loop beneath the boiler. Attach the filling loop, open both valves slowly, and watch the pressure gauge until it reaches 1.0 to 1.5 bar. Close both valves, then remove and store the filling loop.
