exit through the slot of the appliance. The gas connection is G 3/4 "and it is covered by a red protection cap. It is recommended
to foresee a gas interception manual tap near the appliance along the pipeline in an easily accessible position. See in the picture
below, the gas connection and the slot for the tube passage.
The device is delivered with the injector assembly set for G20 - 20mbar gas (factory assembled with ref. 180-0026). In case of
different gas such as G25 or G31, it will be necessary to purchase the related injector assembly (see the reference in the table
here below).
