10.1 Preliminaries - All Systems
Remove the casing panels, see diagram 10.1.
A competent person in accordance with the current issue of
BS6798 should carry out commissioning.
Make sure that the system has been thoroughly flushed out with
cold water.
Refill the system with water, making sure that all the air is
properly vented from the system and pump, diagram 10.2
shows vent point.
Before operating the boiler check that all external controls are
calling for heat. Do not operate the boiler without water.
Allow the system to reach maximum temperature then switch
off the boiler by isolating from the electrical supply.
Drain the entire system rapidly whilst hot, using the drain tap at
the lowest part of the system. Following completion of the hot
flush, add inhibitor to the system.
