The gas control system used in the LEO series meets the requirements for appliances burning gase-
ous fuels in Directives 2009/142/EEc and DIN EN 298, DIN EN 126, DIN EN 13611. The system can be
supplied with a gaseous fuel, second and third family according to EN- 437. first, make sure that the
connected device is intended to be supplied with the type of gas contained in the gas installation. All
the necessary information about the required parameters of the gas can be found on the nameplate
of the fireplace. Before connecting the gas supply pipes, it is necessary to purge them to remove me-
tal filings and other contaminants from their interior. The automatic gas control should be protected
from moisture and dust. These factors may cause irreparable damage to individual components. Gas
supply pipes to the fireplace should be equipped with a ball valve of 1⁄2 inch in diameter. Individual
elements of gas installation cannot be sealed using a Teflon tape or pTfE tape (please use the sealing
elements supplied with the unit). If the gas installation needs to be connected to a settler, install it
according to fig. 10. The settler protects the controller from gas contaminants.
