Stick the self adhesive arrow indicator, from the loose items
pack, to the data label against the rating the boiler is set to.
Allow the water system to warm up and set the pump to give the
correct temperature difference of 11
o C (20 o F) between flow and
return.
There should be no undue noise in the pipework or heat
emitters, no pumping over of water or entry of air at the open
vent above the cold water cistern.
Allow the water system to reach maximum working temperature
and examine for water soundness. Whilst hot the system should
be drained rapidly to complete the flushing process.
Refill the system, vent and check for water soundness.
7.3 Operational Checks
Check operation of the flame failure device as follows, with the
main burner alight, turn the gas valve control knob “A” fully
clockwise to its stop '
', this will put out the main and pilot
flames. The safety device should close within 60 seconds, a
click from the valve will indicate this.
Remove the pressure gauge and refit the pressure test point
screw “G”. Make sure that a gas tight seal is made.
Turn thermostat knob “B” to “O” and relight the pilot burner as
Section 7.2.

7.5 Completion and User Information
Instruct and demonstrate the efficient and safe operation of the
boiler and heating/domestic hot water system.
Hand the Instructions for Use to the user, for keeping and make
sure that they are understood.
Advise the user that to ensure the continued efficient and safe
operation of the boiler it is recommended that it is checked and
serviced as necessary at regular intervals. The frequency of
servicing will depend upon the particular installation conditions
and usage, but in general once a year should be enough.

Safety (Installation and Use) Regulations, Section 35, which
imposes a duty of care on all persons who let out any property
containing a gas appliance.
Advise that the boiler is fitted with a Flue Blockage Safety
Device and refer to the Instructions for Use.
