Checking the supply pressure and heat input

Before checking the supply pressure, make sure that the gas has been set up correctly
!
on site.
The pressure (connection and output) must be measured when the oven is running, i.e. the burner must be
switched on. The burner is ignited by following the procedure indicated in paragraph 6.3: START-UP PHASE.
The gas supply pressure check must be carried out with a differential pressure gauge, connected to the pressure
tap via a special hose.
The following images show the gas control unit and electronic control unit; the points where the pressure gauge
and pressure adjustment screw are connected are also indicated.
Key:
1. SV1;
2. SV2;
3. Inlet pressure tap (Pin);
4. Outlet pressure tap (Pout);
5. Chamber compensation (not in use);
6. Outlet gas pressure modulator.

All adjustments must be made in the order shown.
Check the inlet and outlet pressures using the specific metering units.
!
Once the check has been completed, close the seal with the appropriate screws.
Recommended tightening torque: 1.0 Nm.
1. Remove the modulator's plastic cap (E).
2. Inlet pressure:
Connect the pressure gauge to the inlet pressure tap (3-
Pin) via the special hose, once the relative sealing screw
has been removed.
After the pressure gauge has been connected, open the
gas shut-off valve (set up in the system) and switch on
the burner (start the oven). Measure the inlet pressure
and check that the values correspond to what is shown
in the table.
If the measured pressure does not fall within the
parameters shown in the table, the oven cannot be
started up.
The non-compliance of the pressure values must be reported to the body responsible for supplying the gas;
this body will then have to check and resolve the problem.
When the measurements have been taken, switch off the oven by following the procedure described in
paragraph 6.7 (SWITCH-OFF
PHASE), close the gas shut-off valve, detach the pressure gauge hose from the pressure tap (3-Pin), then
replace and tighten the pressure tap sealing screw.
