regular intervals. The frequency of servicing will depend upon the
particular installation conditions and usage, but in general once a
year should be adequate. It is the law that a competent person,
such as British Gas or other CORGI registered personnel, must
carry out any service work.
Service the appliance by following the full procedure detailed
below:
6.1
COMBUSTION CHECK
The appliance incorporates a flue sampling point on the
appliance flue elbow, or appliance vertical flue adaptor. If
suitable equipment to analyse the flue gas is available, remove
the sampling cap and fit a 6 mm inside diameter sample tube.
When the appliance is operating at maximum output check that
the gas supply pressure is 20.0 mbar, using the inlet pressure test
point is located on the gas supply cock.
Before commencing any service operation, ISOLATE the mains
electrical supply, and TURN OFF the gas supply at the main
service cock.
