[. . . ] The combustion chamber and flues are made of electro-galvanised steel sheeting. The temperature is set using the safety taps provided. It goes from low (minimum) to high (maximum) through a range of easily selectable intermediate levels. connecting the gas supply, checking power rating, transforming or adapting the appliance to run on other types of gas, and commissioning, must all be done by contractors authorised by the local Gas Board in accordance with local and national legislation. [. . . ] The following are the operating pressure tolerances to obtain the nominal power according to the agreed nozzles: - from 15 to 22. 5 mbar for gases of the second family - from 25 to 45 mbar for gases of the third family (propane). Capacity should only be measured when the appliance is at a standstill. The heat value can be obtained from your local Gas Board. To obtain the nominal and minimum capacities in relation to the nominal pressure, consult table (1- Gas Flow Setting). 3 5 3 6 1 2 4 22 The appliance will not work outside the above pressure threshholds. To adjust the capacity to its minimum value, use the data in tables 1 (Gas Flow Regulation table). If you wish to check the nominal capacity further, you may do so using a gas meter according to the so-called WARNING ”volumetric method”. It is not possible to adjust nominal capacity in adIt is normally enough, however, simply to check that the vance. nozzles are functioning correctly. Checking input pressure (Fig. 3) Input pressure should be measured using a gauge (e. g. Remove screw (22) from the pressure socket and connect it to the tube on the gauge; after measuring, the screw should be retightened absolutely airtight (22). Checking power rating when using LP gas Check that the type of nozzles used match table 1 specifications. Check that the output pressure regulator installed collaterally to the plant conforms to the specifications laid down in paragraph "Testing the power rating" (see data plate and measure the pressure). 013- 03 - Gas pasta cooker 10 Checking the pilot light When correctly adjusted, the pilot light flame will completely surround the thermocouple and will not flicker; ; if it does, adjust the pilot flame as described in paragraph “Pilot burner adjustment”. Replacing the main burner nozzle To change nozzle (30), open the doors. Unscrew the nozzle from the nozzle holder using a 12 spanner; replace with a new nozzle (see “TECHNICAL DATA” table). If necessary, to make changing the nozzle easier, loosen screws (39) to remove the air adjustment sleeve. Checking the primary air The appliance can be adjusted. Air volume flow is correct when there is sufficient protection against the flame rising when the burner is cold or light-back when it is hot. Position the ring at measurement “A” (Fig. 1) indicated in table 1 for type of gas. Pilot burner adjustment (Fig. 2) The pilot burner is easily accessible once the doors have been opened. Remove screw (35) and adjust the flame with a screwdriver. Once adjusted, replace and tighten screw (35) inserting the relative gasket. 3) Loosen the gas piping and thermocouple hoses, then All parts must be replaced by authorised techni- loosen the screws fixing the gas supply to the gas ramp and insert a new tap.
