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.
7.14.1 Checking the ionisation current (flame current)
Accessing the service level on the RC35
▶ Open flap on RC35.
▶ Press
+ + simultaneously to open the SERVICE
MENU menu.
▶ Turn rotary selector anticlockwise until diagnosis is selected
(marked with ).
▶ Press to open the SERVICE/DIAGNOSIS menu.
▶ Turn rotary selector anticlockwise until diagnosis is selected
(marked with ).
▶ Press to open the SERVICE/DIAGNOSIS menu.
▶ Hold down and turn rotary selector simultaneously to
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 31).
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 Check for water 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.
7.16 Installing casing parts
▶ Hook in the rear side panels first at the bottom (excluding insulation)
[3], then raise slightly and hook in at the top.
▶ Using locking screws, secure the rear side panels to the boiler back
panel [3].
▶ Hook in the front side panels first at the bottom (including insulation)
[2], then raise slightly and hook in at the top.
▶ Using locking screws, secure the front side panels at the front [2] of
the boiler.
▶ First hook in the bottom of the front panel [1], then raise slightly and
hook in at the top.
▶ With locking screws, secure the top of the front panel [1] to the
boiler.
▶ Affix the clear pocket containing the technical documentation in a
clearly visible spot on the side of the boiler.

7.17 Informing the user, handing over technical
documents
▶ 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 7.18).
▶ Together with the user, carry out a system shutdown and restart.
▶ Explain to the customer what to do in an emergency, e.g. a fire,
referring to the operating instructions.
▶ Hand over the technical documents to the user.
The menu items shown will vary depending on the
heating system.
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.
