Necessary tool:
■ Differential pressure meter , suggested model: Testo 510
How to measure the static and dynamic , see :
1. Unscrew the inflow gas pressure screw and connect the differential pressure meter;
2. Open the gas tap;
3. Read the static pressure value. The optimal value depends on the gas type according to UNOX specification;
4. Measure the inflow dynamic gas pressure while running the gas fumes test 1 (maximum power) and the
gas fumes test 2 (minimum power). The values should be closed to the static value.
How to measure the static and dynamic outflow pressure, see Figure 12:
1. Unscrew the outflow gas pressure screw and connect the differential pressure meter;
2. Open the gas tap and run the oven;
3. Read the pressure value. The value should be idea 0 ± 0.7 mbar (0 ± 0.28 inch wc);
4. Measure the static outflow gas pressure and check if the value is about 0 mbar (0 in H2O);
5. Measure the dynamic outflow gas pressure when running the gas fumes test 1 (maximum power and the
gas fumes test 2 (minimum power). The values should be about 0 ± 0.7 mbar (0± 0.28 In H20) as explained
in section 4.4 Influence of the gas valve inflow pressure.
