system the shunt pump must be adjusted to give the
minimum flow rate given in Table 4, when that part of the
system intended to be used for dissipation of residual
heat only is in operation.
26 HANDING OVER
ROUTINE OPERATION
Full instructions covering routine lighting and operation of
the boiler are given on the Lighting and Operation
Instruction Label located on the inside of the casing door.
Draw the attention of the boiler owner or his representative
to the Lighting and Operating Instruction Label on the
inside of the casing door. Give a practical demonstration of
the lighting and shutting down of the boiler.
Describe the function of the boiler and system controls and
show how they are adjusted and used.
Describe the function of the downdraught thermostat if
fitted.
Hand over these and the User’s Instructions to the customer
and request him/her to keep them in a safe place for ready
reference.
IMPORTANT. Point out to the owner that the boiler must have
regular maintenance and cleaning, at least annually, in order
to ensure reliable and efficient operation. Regular attention
will also prolong the life of the boiler and should preferably be
performed at the end of the heating season.
Recommend that a contract for this work should be made with
the regional gas authority or a Corgi registered heating
installer.
