5.2.2 Gas supply
Before mounting, check that the gas meter has sufficient capacity (in
m
3
/h). To do this, you should bear in mind the consumption of all
appliances. If the capacity of the gas meter is too low, inform the gas
supply company.
The boilers are preset to run on G20 gas (gas H) and can be adapted to
run with the following gases:
G25 (gas L),
G31 (gas P),
Important
To use a different type of gas, contact an approved assistance
service.
5.2.3 Electrical power supply
Power supply voltage 230 V AC/50 Hz
Caution
Please ensure the polarities shown on the terminals are followed,
i.e live (L), neutral (N) and earth ( )
5.2.4 Circulating pump
The boiler's water flow rates must be higher than or equal to the
specifications in the table below:

Minimum flow rate litres/hour 800 1500 2000 2250
Maximum flow litres/hour 2450 3500 4600 4800
1 Q flow rate (litres/hour)
2 {3}H pressure in metres of water column (mWC)
3 Operating water flow rate at nominal heat output = 1330 litres/hour
where ∆T = 30 °C
4 Operating water flow rate at nominal heat output = 2000 litres/hour
where ∆T = 20 °C
5 Operating water flow rate at nominal heat output = 2660 litres/hour
where ∆T = 15 °C
ΔT Temperature difference between the flow water and the return
water in the boiler
