First of all it is necessary to check that the device is in conformity with the
type of gas distributed. For this purpose, you must refer to the indications
shown on the identification plate. The gas supply must be appropriated to
the power of the heater and be equipped with all the security and
inspection devices required by current standards. A precise study must be
carried out on the diameters of the piping depending on the type and the
flow of gas and the length of the piping. It is necessary to make sure that
pressure drops in the piping do not exceed 5 % of the supply pressure.
The gas connections must be made in conformity with the
recommendations for indoor.
