Preliminary electrical system checks to ensure electrical safety must be

carried out by a competent person i.e. polarity, earth continuity, resistance to

earth and short circuit.

ILLING THE

EATING

YSTEM

Remove the panels of the case and lower the control panel (see section

3.3 for further information).

Open the central heating flow and return cocks supplied with the

connection kit.

Unscrew the cap on the automatic air release valve one full turn and leave

open permanently.

Close all air release valves on the central heating system.

Gradually open valve(s) at the filling point (filling-loop) connection to the

central heating system until water is heard to flow, do not open fully.

Open each air release tap starting with the lower point and close it only

when clear water, free of air, is visible.

Purge the air from the pump by unscrewing anticlockwise the pump

plug and also manually rotate the pump shaft in the direction

indicated by the pump label to ensure the pump is free.

Close the pump plug.

Continue filling the system until at least 0.7 bar registers on the pressure

gauge.

Inspect the system for water soundness and remedy any leaks

discovered.

ILLING OF THE

YSTEM

Close all hot water draw-off taps.

Open the cold water inlet cock supplied with the connection kit.

Open slowly each draw-off tap and close it only when clear water, free of

bubbles, is visible

UPPLY

Inspect the entire installation including the gas meter, test for soundness

and purge, all as described in BS 6891:1988.

Open the gas cock (supplied with the connection kit) to the appliance and

check the gas connector on the appliance for leaks.

When the installation and filling are completed turn on the central heating

system (section 3.4) and run it until the temperature has reached the boiler

operating temperature. The system must then be immediately flushed

through.

The flushing procedure must be in line with BS 7593:1992 code of practice

for treatment of water in domestic hot water central heating systems.

During this operation, we highly recommend the use of a central heating

flushing detergent (Fernox Superfloc or equivalent), whose function is to

dissolve any foreign matter that may be in the system.

Substances different from these could create serious problems to the

pump or other components.

The use of an inhibitor in the system such as Fernox MB-1 or equivalent is

strongly recommended to prevent corrosion (sludge) damaging the boiler

and system.

Failure to carry out this procedure may invalidate the appliance

warranty.
