Gas Connection
Before connecting the appliance, make sure that the data on the identification plate corresponds to that of
the gas supply network. If the gas indicated on the plate is not the same available in the premises, follow
the instructions in chap. Adjustment for operation with different gases on page 47.
- Connection to the gas supply network must always be carried out using rigid or flexible metal piping with
proportionate cross-section, inserting a sealing gasket suitable for gas use.
- Connections between the 3/4"G piping from the appliance and the gas pipes should preferably be carried
out using a three-piece metal joint, in order to facilitate connection and dismantling if necessary.
- Seal the joint threads using TFE tape (tetrafluoroethylene) or other materials declared by their
manufacturers as being suitable for LPG too.
- Always insert a cut-off tap between the appliance and the gas supply pipes, in a position that makes it
easy to handle and turn off after use.
- During connection between the gas piping and the appliance, make sure you do not cause any kind of
stress to the appliance itself.
- Gaskets must be metallic or of other elastic materials that cannot be altered by the gas distributed.
- Copper piping junctions must be realized using mechanical couplings without gaskets or putty.
- After connection to the gas supply, check the absence of any leaks in the joints and connections using
water and soap or a suitable leak detection product.
