Maintenance Of The Air/Flue Gas Drain Connection Flues; Temperature Sensor - REMEHA Gas 110 Eco 115 Installation, User And Service Manual

10.4 Maintenance of the air/flue gas drain connection flues

The connection pipes must be checked at least once a year.
- Check the seals.
- Check the condensates evacuation pump in the boiler and on the
pipe if used.

10.5 Temperature sensor

The resistance values at the various temperatures are indicated in
the tables on the next page.
If a defective sensor is detected, it is possible to check the resistance
at the various temperatures using a measuring device with a
corresponding measurement range (e.g. a multimeter). In order to
obviate incorrect measurements, the sensor must be disconnected
from the connector bar in the boiler distribution panel.

- Replace the leakproof seals and sections of pipe if these no longer
offer a perfect guarantee of leak tightness after being dismantled
during a maintenance operation (only for the visible part of the
flue).
