The procedures detailed in this chapter must
be carried out only by a Gas Safety Reg-
istered Engineer . Thus you are advised to
contact an Authorised Service Agent.
For Ireland (IE), the servicing work must be
carried out by a competent Person.
For efficient and continuous operation of the
boiler you are advised to have, at least once
a year, maintenance and cleaning done by an
Approved Service Engineer.

supply by turning off the fused spur isolation

the gas cock, before carrying out any proce-
dures, whatsoever, for cleaning, maintenance,
