3.1.1 Gas conversion
Conversion of the unit to a type of gas other than the factory setting
must be done by an authorized technician, using original components
and in compliance with current regulations in the country where the
unit will be used.
The unit can operate with methane gas or LPG. It is factory-set for one of the two types
of gas, as indicated on the packaging and technical data plate. To operate the unit with
another type of gas, a conversion kit must be used:
