Warning!

It is a criminal offence to work on a gas appliance if you are not qualified, and licensed to do so.

ALWAYS consult the manufacturers user instructions for guidance. The instructions above are for guidance only. If unsure of any procedures, call a boiler specialist, who holds the relevant qualifications, and GAS Safe Registration.
