resist temperatures of up to at least 212°F (100°C). Avoid re- strictions in the case of flexible hose pipes, do not fit elbows on metal pipes anywhere along the drainage line. Also avoid horizontal sections in which water might collect (minimum gra- dient 5%).

WARING: BLOCKING THE DRAIN IS HAZARDOUS.

6. GAS CONNECTION

6.1 WARNINGS

•Make sure the appliance is set up for the type of gas with which it will be supplied.

•The gas inlet connector is yellow in colour.

•Before installing consult your local gas utility company to check the compatibility between the available supply and the consumption of the appliance.

•Before hooking up the appliance to the gas pipeline remove the plastic protective plug from the gas connector.

•Fit a rapid gas shut-off cock upline from the appliance in an easily accessible position.

•On completion of installation, use soapy water to check gas connections for leaks.

•Itisnotpossibletoadjustthecombustionairventilationcapacity.

•If the appliance is hooked up to a supply with a different gas type with respect to the factory setting, after making the necessary changes check that it is working correctly (see heading 8 "Operation Check").

Important:

-Do not obstruct the safety outlet C1.

-Do not connect the safety outlet C1 to the drainage system.

Note:

If water comes out of the AIR-BREAK (safety outlet C1) this means the drain C is blocked. Any elimination of the obstruction must

be carried out by specialised technical personnel.

- OVEN level C -

Connect drain fitting “C” to a drain pipe of the same diameter which is between 0.5 and 3 metres in length and is resistant to temperatures of at least 100°C. The drain pipe must be siphoned (height 80 mm) to an open drain “O” (“Air-Break”) or floor grating (see Fig. 12b) in order to prevent any back-flow from the sewage system from reaching the piping inside the oven or oven chamber. Check the hoses and elbows on metal pipes for kinks or pinching along the entire drain line and make sure the drain line has a minimum gradient of 5° to prevent water from collecting inside the

system.

Important: The drain system must be installed so that any vapours from the open drain do not enter the aeration vents under the appliance.

6.2 NOMINAL HEAT OUTPUT

For data concerning the nominal heat output refer to "Technical Data" in Table 1.

This parameter is determined by the pressure of the gas supply and the diameter of the gas valve diaphragm (nozzle).

The appliance nominal heat output must always be checked (by the authorised installer or by the gas utility company), both in the case of new installations or following maintenance work.

6.3CHECKING THE SUPPLY PRESSURE (Fig. 2a)

The gas supply pressure must be measured upline from the gas shut-off cock with the appliance operating, using a pressure gauge with minimum resolution of 0.1 mbar and proceeding as outlined below:

1) Remove the left hand side panel to gain access to the gas valve; 2) Loosen sealing screw "C" from the gas valve pressure test point and connect the pressure gauge hose in its place;

3) Open the gas shut-off cock;

4) Start a mixed cooking cycle (see "Instructions for use") in such a way that all the burners can be lit;

5) Check that the pressure reading is within the values given in the following table:

GAS TYPE		PRESSURE (MBAR)
	Nom.	Min.	Max.
NATURAL	7"wc (17,4mbar)	3"wc(8,7mbar)	10"wc(26,1mbar)
PROPANE	11"wc (27,4mbar)	8"wc(19,9mbar)	13"wc (32,3,4mbar)

If the values are not within the values shown in the table the appliance will not function.

In this case inform your gas utility company of the problem;

6)Once you have measured the supply pressure stop the cooking cycle and close the gas shut-off cock.

7)Disconnect the pressure gauge and carefully refit and tighten sealing screw "C";

8)Refit the previously removed side panel.
