FILLING THE SYSTEM
Open vented systems:
▶ Ensure all system and boiler drain points are closed.
▶ Open all radiator valves.
▶ Turn on the water supply to the system header tank and allow the
system to fill.
Sealed systems:
▶ Fill the system via a WRAS approved filling loop to 1 bar then turn the
valve anti-clockwise to close.
Opened vented and sealed systems:
▶ Air will be removed from the boiler heat exchanger via the Auto Air
Vent mounted on top of the heat exchanger.
▶ Vent all radiators and the primary side of the hot water cylinder,
tighten when completed and check the system and correct any leaks.
Sealed systems only:
▶ If required increase system pressure back to 1 bar.
▶ Isolate and remove filling loop connection to system.

WATER TREATMENT
ENSURE THAT THE SYSTEM HAS BEEN CLEANED AS ON PAGE 9 OF
THESE INSTRUCTIONS
.
FLUSHING (Central Heating):
▶ Switch off the boiler.
▶ Open all drain cocks and drain the system while the appliance is hot.
▶ Close drain cocks and add a suitable flushing agent at the correct
strength for the system condition in accordance with the
manufacturer's instructions.
▶ Run the boiler/system at normal operating temperature for the time
stated by the manufacturer of the flushing agent.
▶ Drain and thoroughly flush the system to remove the flushing agent
and debris.
INHIBITOR (Central Heating):
▶ Check drain cocks are closed and all radiator valves are open before
adding a suitable inhibitor compatible with aluminium (or combined
inhibitor/anti-freeze if the system is exposed to freezing conditions)
to the heating system water in accordance with the manufacturers
instructions.
▶ Fill system as described in section 5.2.
▶ Set all controls to maximum.
▶ Record the date when the inhibitor was added to the system.
WATER TREATMENT
Suitable water treatment products can be obtained from the following
manufacturers:
WARNING:
ELECTRIC SHOCK
▶ ISOLATE THE MAINS SUPPLIES BEFORE STARTING
ANY WORK AND OBSERVE ALL RELEVANT SAFETY
PRECAUTIONS
NOTICE:

NOTICE:
SOFTENED WATER
▶ ARTIFICIALLY SOFTENED WATER MUST NOT BE
USED TO FILL THE CENTRAL HEATING SYSTEM.
The pH value of the system water must be less than 8 or
the appliance guarantee will be invalidated.
NOTICE:
▶ The concentration of inhibitor in the system should be
checked every 12 months or sooner if system content
is lost.
▶ The addition of sealing agents to the system water is
not recommended as this can cause problems with
deposits left in the heat exchanger.
