5.1.3 Checking the input pressure (Fig. 1)
Input pressure should be measured using a fluid measuring gauge
(e.g. a gooseneck pipe, min. resolution 0.1 mbar).
Remove lock screw (22) from the pressure intake tube and connect the
gauge hose: once measurement is complete, replace the screw (22).
5.1.4 Power check with volumetric method
Using a gas meter and a stopwatch, you can read the volume of gas
output per time unit. The correct volume corresponds to the value
"E" expressed in litres/hour (l/h) or litre/minute (l/min).
The following formula is used to calculate the value of “E”:
It is important measure the power when the appliance is in standby
status.
The calorific power value can be requested from the local gas com-
pany.
The nominal power and the minimum power with respect to the
nominal pressure are obtained by consulting the table for the
adjustment of the gas passage (table 1).
WARNING
There is no pre-adjustment device for the nominal
power.
5.1.5 Power check for operation with liquid gas
Check if the type of nozzles used meet manufacturer requirements.
Check that the pressure reducer installed in the system has an outlet
pressure which is compliant with paragraph 5.1.2 "Check of power"
(can be checked on the data plate of the appliance or by measuring
the pressure).
5.1.6 Check of pilot flame
For proper regulation, the pilot flame must surround the thermo-
couple and it must have a perfect appearance. Otherwise, adjust the
air flow to the pilot.
5.1.7 Checking the primary air
Both the oven and the open flames are equipped with primary air
adjustment.
Air volume flow is correct when there is sufficient protection
against the flame rising when the burner is cold or in case of flash-
back when the burner is hot.
