SECTION 5 MAINTENANCE AND SERVICING
In this section you can find a few maintenance suggestions and the instructions which are
necessary to technical assistants in order to adjust the gas valve and replace the gas.
5.2 HOW TO ADJUST THE GAS VALVE
The gas feeding circuit is provided with a gas valve equipped with double knock and
pressure regulator to control the gas inlet flow. All models are supplied to operate with
natural gas and are equipped with an LPG conversion kit.
During the final tests each
unit is set to operate with natural gas. After installation it is necessary to check the
pressure to the
burner. All controls must be carried out with an operating unit free from its
outer casing.
The gas valve adjustment must be performed by
qualified personnel
. To this
regard, ROBUR S.p.A. can dispose of a network of Assistance Centres which can be
reached through the point of sale, the local agent or by calling directly the Customer
Assistance of ROBUR S.p.A. (tel. +39 035/888111).
