How do I apply for sub-entry?

These requests are equivalent to a new activation and must be presented to a retail firm in accordance with the methods set down who will transmit this to the distributor within 2 working days. If the client’s system has, in the meantime, been modified (with enlargement or extraordinary maintenance work) or transformed (previously fuelled with a different type of gas), documentation required by the distributor to assess safety requisites will be required of the client by the retail firm.
