Checking tightness during operation

NOTICE:
Risk of material damage due to a short circuit!
▶ 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.
▶ Never spray or allow leak detection agent to drip onto cable entries,
plugs or electrical cables.
▶ To prevent corrosion, carefully wipe off the leak detection agent
afterwards.
▶ With the burner operational, use a foaming agent to test all joints
along the entire burner path, such as:
• Test nipple
• Locking screw for gas supply pressure
• Screw fittings (also at the gas connection) etc.
The agent must be approved for gas tightness testing.
