15. The burner pressure is factory set.
16. From the table opposite check that the main burner
pressure is correct after the appliance has been running
for 10 minutes. If necessary, adjustment to main burner
pressure can be made by altering the regulator as shown
(Fig. 90).
17. Check for gas soundness, with main burner alight,
using leak detection fluid.
18. Turn the boiler thermostat to the OFF position
marked 0. Screw home the pressure test point screw.
Turn the boiler thermostat knob to the required setting.
19. The boiler and system should be run and then flushed
and treated in accordance with
BS 7593:1992 and the flushing agent / inhibitor
manufacturers instructions. When all the air has been
removed from the water circuit, the pump and radiators
should be balanced to achieve the design temperature
drop across the system.
20. Make a final check for gas soundness and set any
timer control, room thermostats etc. to the customer's
specific requirements.
21. The boiler is protected by an integral frost-stat, but if
the boiler is not to be used for a long period of time, the
system should be drained.
NOTE: The frost thermostat operates even if the
boiler thermostat is in the OFF position and it is
necessary therefore, if the system is drained, for the
external electrical and gas supplies to be isolated.
It is recommended that a label be affixed to the
appliance to draw attention to the fact that the system
has been drained.
WARNING - If the system is filled with very cold
water and the boiler lit, the action of the frost
protection thermostat will prevent the boiler from
shutting down before the water temperature reaches
10°C.
22. Carefully read and complete all sections of the
Benchmark Commissioning Checklist at the rear of this
publication that are relevant to the appliance and
installation. These details may be required in the event of
any warranty work. The publication must be handed to
the user for safe keeping and each subsequent regular
service visit recorded.
23. For IE, it is necessary to complete a “Declaration of
Conformity” to indicate compliance to I.S. 813. An
example of this is given in I.S. 813 “Domestic Gas
Installations”. This is in addition to the Benchmark
Commissioning Checklist.
