Checking for leaks during normal operation

CAUTION: Risk of system damage due to short-circuits.
▶ Cover the fan and other at-risk areas before searching
for leaks.
▶ Do not spray leak detector onto cable conduits, plugs
or electrical connecting leads. Do not let it drip onto
them either.
▶ Start up the boiler and check the flange for leaks at maximum output.
▶ Check all around the flange for leaks using a leak detecting agent.
▶ For details of other leakage checks, refer to Section 7.17, page 38.

Testing ionization current

To ensure trouble-free operation, the ionization current at medium and
maximum output (when flame is lit) should be at least 3 μA.
The (flame) ionization current can be read off on the RC35 programming
unit under "SERVICE MENU DIAGNOSIS/MONITOR READING"
( Section 7.15.1, page 37).
A PC with Logamatic ECO -Soft4000/EMS software and
a service key can also be used as a monitoring device.
Please contact Buderus for more detailed information.
