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.

 - 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 effi

  cient. 

Filling the Heating System:
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;
Lift the cap on the automatic air release valve and leave open 
permanently;
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;
Purge the air from the pump by unscrewing the pump plug anti-
clockwise, also manually rotate the pump shaft in the direction 
indicated by the pump label to ensure the pump is free;
Refit the pump plug;
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.

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 7593:1992 (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 BS7593:1992.

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,
