The gas pipe is to be planned and realized
according to the laws, norms, rules and provisions
in force. The diameters of the pipes are to be
calculated, considering the power of the installed heater and its distance from the counter;
they are to be dimensioned so that the total pressure loss between the counter and any
heater doesn't exceed the value allowed by the norms in force.
Install near the heater a cock and a gas filter. As regards natural gas, be sure that the
counter is able to deliver the required gas quantity. As regards propane, adopt a two-stage
pressure reducing system: install a first-stage pressure device reducer near the tank,
calibrated at 1,5 bar and a second reducer just before the pipe enters the room.
