10.1 Warnings
The procedures detailed in this chapter
must
be carried out only by a Gas Safe Regis-

tact an Authorised Service Agent.
For Ireland (IE), the servicing work must be
carried out by a competent RGII registered.
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.
Isolate the appliance from the electricity
supply
by turning off the fused spur isolation
switch adjacent to the appliance

Turn off the gas cock
, before carrying out
any procedures, whatsoever, for cleaning,
maintenance, opening or dismantling boiler
