Check that the boiler thermostat and all remote controls are
working correctly.
Do not attempt to adjust the thermostat calibration screw.
Test the boiler for spillage of the flue products at the draught
diverter as detailed in the current issue of BS5440 Part 1. If an
extract fan is fitted in the premises, refer to Section 3.6.
7.2 Commissioning the System
Allow the system to warm up and set the pump adjuster to a
design position which gives the correct temperature difference
of 11
o C (20 o F) between the flow and return. There should be no
undue noise in the system, pumping over or entry of air at the
open vent above the cold water feed and expansion cistern.
Allow the system to reach maximum working temperature and
examine for water soundness.
The system should then be drained down as rapidly as possible
to complete the flushing process.
The system should then be refilled, vented and examined for
water soundness.
