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.

WARNING:
Danger to life due to poisoning!
Risk of poisoning due to escaping flue gases when the air supply is
inadequate.
▶ Make sure that a supply of air is available in every operating mode
through corresponding openings to the open air.
▶ Make the user aware of the need for and function of the ventilation
and combustion air apertures.
▶ Make the user familiar with the heating system and the boiler
operation.
▶ Make the user aware that the boiler and control unit must only be
opened by qualified contractors.
▶ Confirm commissioning in the report (
Chapter 17.6).
▶ Together with the user and referring to the operating instructions,
perform a shutdown and restart.
▶ Point out the user that frequent refilling of heating water is a sign that
the system is faulty and/or leaking (ensure required water quality
according to the operator's log).
▶ Inform operator about the required water quality and point out where
the heating water must be refilled.
▶ Explain to the customer what to do in an emergency, e.g. a fire,
referring to the operating instructions.
