Operating information

Maintenance information

We recommend having the boiler system
serviced regularly to ensure fault-free,
efficient and environmentally responsi-
ble operation.
The boiler should be cleaned regularly to
prevent the flue gas temperature rising
with increasing contamination, which
leads to higher energy consumption.
We recommend the installation of a flue
gas thermometer. Monitoring the flue
gas temperature highlights incorrect
burner adjustment and the level of boiler
contamination.
Excessive flue gas temperatures
through contamination or altered burner
adjustment reduce efficiency. Where
necessary, clean the boiler or adjust the
burner settings.
