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.

Electricity supply

- Check that the voltage and frequency of the electricity supply

correspond to the data shown on the boiler data plate;

- Make sure that the earthing connection is efcient.

Filling the Heating System:

ATTENTION!!

CONNECT THE PIPE OF CONDENSATE DISCHARGE

BEFORE REFILLING AND THE DE-AERATION OF THE

HEATING CIRCUIT.

Remove the front casing panel and lower the control panel as

described on page 15.

Open the central heating flow and return cocks supplied with

the connection kit;

Open the manual air vent positioned at the side of the primary

exchanger (2). The valve is already connected to a discharge

pipe related to the condensate trap.

Close all air release valves on the central heating system;

Gradually open the valves at the filling point (filling loop) until

water is heard to flow, do not open fully;

Open each air release tap starting with the lowest point and

close them only when clear water free of air is visible;

Continue filling the system until at least 1.5 bar registers on the

pressure gauge;

Inspect the system for water tightness and remedy any leaks

discovered.

importaNt!

maNually VeNt the heat exchaNger at the maNual air VeNt. failure

to VeNt adequately may damage the heat exchaNger (page 9, legeNd

2).

Filling of the DHW System:

Close all hot water draw off taps;

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

Slowly open each draw off tap and close them only when clear

water, free of bubbles, is visible.

Gas Supply:

Inspect the entire installation including the gas meter and test

for tightness. The entire installation should be in accordance

with the relevant standards. In GB this is BS 6891 and in IE this

is the current edition of I.S.813.

The connection on the the appliance is a 15mm (22mm on

38Kw) nut and olive located at the rear of the gas service cock.

If the gas supply serves other appliances, ensure that an

adequate supply is available both to the boiler and the other

appliances when they are in use at the same time.

Pipe work must be of an adequate size. The final pipe size

must not be smaller than the appliance inlet size.

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

appliance and check the gas connection on the appliance for

leaks.

Water Treatment:

The boiler is equipped with a stainless steel heat exchanger.

The detailed recommendations for water treatment are given

in BS 7593 (Treatment of water in domestic hot water central

heating systems); the following notes are given for general

guidance;

If the boiler is installed on an existing system, any unsuitable

additives must be removed;

Under no circumstances should the boiler be fired before the

system has been thoroughly flushed; the flushing procedure

must be in line with BS7593.

Firstly fill the central heating system with the power off, and

flush through cold, fill the central heating system again, adding

a flushing detergent, run the boiler on central heating until it

reaches its operating temperature and flush the system, refill

the system with a suitable corrosion inhibitor,

Note: Failure to carry out the FlushiNg procedure will result iN the

warraNty becomiNg void.
