IMPORTANT!
SILVER spring (on board pressure regulator) is for
natural gas; BLUE spring (inserted in accessory
packaging) is for propane!!
The section of the gas supply line must be suffi-
cient to ensure the gas flow necessary for full op-
eration of all the appliances connected to the sys-
tem; If the gas pressure is higher than that specified
or is difficult to regulate (not stable), install a gas
pressure regulator (accessory code 927225) in an
easily accessed position ahead of the appliance.
The pressure regulator should preferably be fitted
horizontally, to ensure the right outlet pressure
Inside the package of the accessory pressure reg-
ulator can be found a BLUE spring (for propane
gas).
Installed in the device is a SILVER spring for nat-
ural gas!.
