STARTING UP THE BOILER FOR 1

st

 TIME 

 

After connecting up the water supply, before starting 
up the boiler, carry out the following procedures: 
 

Preliminary procedure 

Do as follows: 

ƒ

 

make sure the power supply for the boiler is the same as that stated on the plate (230V - 50Hz) and that the live, neutral and 
earth connections have been properly connected; 

ƒ

 

make sure the type of gas being supplied is the same as the type for which the boiler has been tested and calibrated; 

ƒ

 

make sure the unit is properly earthed; 

ƒ

 

make sure there are no flammable liquids or materials in the immediate vicinity of the boiler; 

ƒ

 

make sure that any shut-off valves in the heating circuit are open; 

ƒ

 

open the gas cock and check the gas seals, making sure the counter shows no sign of leaks; in any case, double check by 
using a soapy solution and eliminate all eventual leaks. The checking procedure for the gas burner attachment is carried out 
with the boiler working; 

ƒ

 

make sure the electrical mains switch is OFF; 

ƒ

 

remove the front cover by pulling it forwards; 

ƒ

 

undo the side screws and rotate the panel downwards  

 

FILLING THE SYSTEM  

 
Fill the heating system as follows, making sure that the gas cock is closed: 

 

open the tap on the filling loop and fill the system until a pressure of 1.5 bar has been 
reached (light no. 7 fig.2) and then 

close the tap 

on the filling loop; 

 

make sure the cap on the auto air vent is slightly loose to allow air to escape from the 
system (see fig. 3). 

 

undo the cap on the circulation pump to eliminate any eventual air locks. It is a good 
idea to purge all radiators of air at this point too; 

 

before starting up the boiler the water pressure must be checked again; if this is seen 
to be below 0.5 bar, bring it back up to 1.5 bar and then 

close the tap

 on the filling 

loop; 

 

switch on the electrical power supply to the boiler; 

 

turn the selector switch to the WINTER 

7

 

position (see fig.1), after a few seconds the 

pump will come into action; 

 

once the boiler is working, if any noises are heard in the system, repeat the above air 
purging procedures until there is no air left in the system; 

 

check there are no obstructions in the exhaust duct; 

 

check the pressure in the system: if this has gone down, restore it until the pressure gauge shows 1.5 bar. 

Close the tap on 

the filling loop 

once this operation is completed;
