MAINTENANCE

10.1 Warnings

The procedures detailed in this chapter
must be carried out only by a Gas Safe
Registered Engineer. Thus you are ad-
vised to contact an Authorised Service
Agent.
For Ireland (IE), the servicing work must
be carried out by a competent RGII reg-
istered 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.
Isolate the appliance from the electricity
supply by turning off the fused spur isola-
tion switch adjacent to the appliance.
Turn off the gas cock, before carrying out
any procedures, whatsoever, for cleaning,
maintenance, opening or dismantling boiler
panels.
Other devices i.e. external con-
trols may lead dangerous volt-
age inside the appliance as well.
Ensure they are isolated.
In case of doubt turn off the gen-
eral system switch.
The Engineer should complete the Service
Interval Record at the back of the manual.
