4 Boiler test 

 
Boiler test (or new boiler 
first operation) must be 
performed exclusively by 
qualified personnel. 
 
4.1 Preliminary checks 
Before carrying out any test 
(or starting the boiler for the 
first time), perform the 
following checks: 
- the installation must comply 
with applicable laws; 
- the flue gas outlet duct and 
the end section are installed in 
compliance with instructions: 
when the boiler  is switched 
on there must be no
 leakage 
of combustion products
 
from any of the seals; 
- power supply is 230 V - 50 
Hz; 
- system is loaded (water 
pressure gauge reads 0.8/1 
bar); 
- cut-off valves on the system 
pipes are open; 
- gas mains supply according 
to boiler factory-set gas: in 
case of discrepancy, convert 
the boiler to the gas type 
available, see “SWITCHING 
TO DIFFERENT GASES“ 
section in this manual; 
- gas mains tap is open; 
- no gas leaks are detected; 
- boiler is electrically powered; 
- boiler safety valve is not 
locked; 
- no water leaks are detected. 
 
Should boiler not be 
installed complying with 
applicable standards and 
laws, do not start it and 
notify immediately the 
central heating system 
supervisor. 
 
 
 
 
4.2 Turning the boiler on or 
off 

Follow the “Users’ 
Instructions”  
for boiler on 
and off procedure. 

 

5 Maintenance 
 

B

oiler must be yearly serviced 

to ensure efficient and trouble- 
free operation. 

 

 
Maintenance (or repair) 
operations must be 
performed exclusively by 
qualified personnel. 
 
Disconnect the boiler from  
power mains before 
beginning any maintenance 
procedure either involving 
replacement of components 
and/or internal cleaning. 
 
Maintenance list 
Routine maintenance must 
include the following checks: 
 
- boiler integrity ; 
- leakage of the boiler’s gas 
circuit and gas mains network; 
- boiler gas supply pressure; 
- minimum and maximum gas 
pressures to the boiler 
nozzles; 
- boiler ignition; 
- boiler combustion 
parameters through flue gas 
analysis (to be performed on a  
two-year basis if boiler is 

 

individually installed. Annually 
to cascade-installed boilers); 
- general condition and leak 
check of flue system including 
anti-wind gust device (BTN - 
balanced flue - model); 
- absence of flue gas reflux 
into the premises and correct 
exhaust of flue gas (BTN – 
balanced flue - model); 
- condition of safety 
thermostat installed on the 
anti-wind gust device (BTN – 
balanced flue - model); 
- air pressure switch (BTFS – 
forced draught - model); 

- general condition of e boiler 
safety devices; 
- water leaks and scaling of 
boiler connections; 
- efficiency of the CH safety 
valve; 
- efficiency of the DHW safety 
valve; 
- expansion vessel working 
pressure; 
- water pressure switch 
efficiency; 
- magnesium anode efficiency. 
 
And the following cleaning 
operations: 
 
- general internal cleaning; 
- gas nozzles; 
- air intake and flue gas outlet 
circuit (BTFS – forced draught 
- model); 
- anti-wind gust device (BTN – 
balanced flue - model); 
- room ventilation grille if 
available (BTN – balanced flue 
- model); 
- heat exchanger (flue gas 
side). 
In case of new boiler first 
operation,  also check: 
- boiler room characteristics 
according to boiler 
requirements; 
- room ventilation grilles, if 
available (BTN – balanced flue 
- model); 
- flue system dimensions, 
diameters and lengths of 
ducts; 
- correct installation of the 
boiler in compliance with the 
instructions in this manual. 
 
Should the boiler not be 
installed according to this 
manual operating require-
ments, if there is no 
immediate danger or hazard 
to people, animals and 
property, notify, both 
verbally and in writing, the 
system supervisor.
