Before mounting, check that the gas meter has sufficient capacity (in
3
m ). To do this, you should bear in mind the consumption of all applian­
ces.
If the capacity of the gas meter is too low, inform the gas supply compa­
ny.
The boilers are designed to run on natural gas G20 and can be conver­
ted to run on G25 or G31 gas.
Note
To use a gas type other than natural gas (G20, G25) or LPG gas
(G31), contact an accredited assistance service.
Caution
Respect the polarities shown on the terminals: live (L), neutral (N)
and earth ( )
