6.20 Checking for leaks during operation

B With the burner operational, use a foaming agent to
test all sealed points in the entire burner gas train, such
as:
• Pressure test nipple
• Plug for gas supply pressure
• Fittings (also at the gas connection) etc.
The agent must be approved for gas tightness testing.
NOTICE: Risk of system damage due to
short circuit!
B Prior to checking for leaks, cover areas at
risk, e.g. the internal water pressure
sensor and the return temperature sensor
in the boiler return.
B Never spray leak detection agent onto
cable entries, plugs or electrical cables.
Do not allow it to drip onto them either.
B To prevent corrosion, carefully wipe off the
leak detection agent afterwards.
