– Turn on the water to the system feed and expansion cistern and
allow the system to fill.
▶ Sealed systems only:
– Check and if required, adjust the expansion vessel pressure using
the Schraeder type valve.
▶ Fill the system to between 1 and 2 bar pressure via a WRAS approved
filling link.
▶ Vent all radiators, retighten when completed.
▶ Monitor the pressure gauge during venting and repressurise if
required.
▶ Check the system and correct any leaks.
▶ Bleed air from at least one of the secondary heat exchanger air vents
