WATER TREATMENT
IMPORTANT: Debris from the system can
damage the boiler and reduce efficiency.
Failure to comply with the guidelines for the
use of water treatment with the appliance
will invalidate the appliance warranty.
FLUSHING (Central Heating):
1
Switch off the boiler.
Open vented systems only: turn off the water
to the system header tank.
Open all radiator valves/drain cocks and drain
the system while the appliance is hot.
Close drain cocks.
2
Add a suitable flushing agent (F) and refill the
system 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 flushing
agent manufacturer.
3
Drain and thoroughly flush the system to remove
the flushing agent and debris.
INHIBITOR (Central Heating):
4
Check drain cocks are closed and all radiator
valves are open.
5
Add a suitable inhibitor (I), (or combined
inhibitor/anti-freeze if the system is exposed to
freezing conditions) to the heating system in
accordance with the manufacturers instructions.
The inhibitor or combined inhibitor/anti-freeze
must not cause damage to the materials within
the boiler (mild steel, stainless steel, copper
and brass) and any other materials/components
within the system.
Open vented systems only: turn on the water
to the system header tank and allow the system
to fill.
Sealed systems only: fill the system to between
1 and 2 bar via a WRAS approved filling loop.
6
Vent the boiler and all radiators; retighten vents
when complete.
7
Record the date when the inhibitor was added
to the system on the guarantee card.
NOTE: The concentration level 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.
