Functional Description with Process Diagrams
5.2.6
Valve Leakage Test
NOTICE
The gas pressure test switch and design and volume of the test section pipework must be set
and designed such that the valve test system reliably detects even the smallest gas leakage
by the valve testing system at maximum combustion thermal output.
EN1648 requires a minimum gas leakage of 0.1% volume in relation to the gas flow rate at
maximum combustion thermal output, but at least 50 dm
3
/hr.
5.2.6.1 Requirements
NOTICE
The function must be mapped.
The pressure switch between the 2 main valves must be mapped either for valve leakage test
or gas pressure min. and valve leakage test.

Type of valve leakage test (0–none; 1–together with pre-purge; 2–after pre-purge is com-
pleted; 4–after burner operation; 5–before operation together with the pre-purge; 6–before
operation after pre-purge is completed)
V1.0.0.0
Type of valve leakage test:
0: no valve leakage test
