7.14 Function tests

During commissioning and the annual inspection, check all regulating,
control and safety equipment for correct function and, where
applicable, for correct settings.

change the setting, e.g. flame current.
The change takes effect when you release the key.
▶ Read off the ionisation current and enter it in the commissioning
report ( Chapter 7.18, page 28).
To ensure fault-free operation, the ionisation current at partial and full
load (with a burning flame) should be at least 15 μA.
▶ Return to operating mode on the RC35.
▶ Close the flap on the RC35.

7.15 Checking for leaks during operation

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