Ensure that the system has been cleaned. Refer to section 4.1.2 of
these instructions.
Inhibitor (Central Heating)
▶ Check drain cocks are closed and all radiator valves are open before
adding a suitable inhibitor 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 via a WRAS approved filling loop to between 1 and 1.5
bar.
▶ Vent all radiators; tighten vents when complete.
▶ Re-pressurise if necessary to 1bar.
▶ Set all controls to maximum.
▶ Record the date when the inhibitor was added to the system in the
Boiler commissioning checklist and in the guarantee registration.
Water treatment products
Suitable water treatment products can be obtain from the following
manufacturers:
6.4 Starting the appliance
1. Check the oil supply is correctly fitted, pressure tested and in good
working order before turning on the oil supply valves to the boiler.
▶ Turn on the main oil supply valve at the tank and draw off at least
2.5 litres of oil until a steady flow of clear uncontaminated oil can be
seen as follows:
– The oil supply to the boiler should be primed before the burner is
operated to avoid unnecessary pump wear.
– The use of an oil suction pump will prime and flush through any oil
supply set up simply and easily, alternatively the following
procedures can be used.
6.4.1 Single pipe gravity feed system:
▶ Disconnect the flexible oil hose and open the isolating valve to
discharge the oil into a suitable container.
▶ If a top entry tank has been used the pipework will need to be primed
before the oil will discharge under gravity.
▶ When completed, close the isolating valve, reconnect the flexible oil
hose.
When the oil reaches the pump, bleed the air from the pump:
▶ Open the isolating valve and the oil pump bleed port [1] to discharge
into a suitable container once the boiler is started up.
▶ Switch on the electricity supply to the boiler.
▶ Set the programmer to ON for CH and DHW.
▶ Turn on the boiler CH control thermostat.
▶ Allow the burner to run through to lockout .

If no oil comes out of the port valve [1], then re-prime the oil line as
detailed above
▶ Wait 2 minutes then press the lockout reset button [K].
▶ Repeat the procedure until a steady stream of oil without air, runs
from the bleed port, then lock bleed port [1].
▶ Switch off the boiler.
6.4.2 Double pipe sub-gravity feed systems and single pipe
suction lift with de-aerator:
▶ Prime the oil supply pipework to prevent oil pump damage.
▶ To prime a de-aerator [2], disconnect the flexible oil inlet hose [7]
from the isolation valve and place in a container of heating oil[6].
Connect a spare flexible oil hose [5], to discharge into container [6].
Open the isolating valve, turn on the power to the boiler and set the
programmer to ON. Prime the de-aerator until there is a steady flow
of oil into container [6]. Turn off the boiler then reconnect the
flexible oil inlet hose [7].
▶ Turn on the boiler, set the programmer to ON and turn the room
thermostat up to create a demand for heat.
The oil level in the de-aerator will drop whilst the oil is being drawn
from the tank. If the de-aerator empties and the burner locks out
before the oil is drawn from the tank, you will have to prime the de-
aerator again.
NOTICE:
▶ Salt based, softened water must not be used to fill
the central heating system.
The pH value of the system water must be between 6.5
and 8 or the appliance warranty will be invalidated.
NOTICE:
▶ The concentration of inhibitor in the system should
be checked every 12 months or sooner if system
content is lost.
▶ In cases where all attempts to find a micro leak have
failed, Worcester, Bosch Group supports the use of
Fernox F4 leak sealer.
