7.3 DOOR TIGHTNESS CONTROL
In case there are door leakages, it is better to tighten the door screwing system after having loosened all lock
nuts.
If the problem remains, verify the elasticity of the ceramic fibre insulation and, if necessary, replace it.
7.4 BOILER SCALING
To extend boiler life and not to cause steel sheet overheating, a periodic scaling is necessary. In case of a
steady scaling do not use a corrosive product.
After the first heating season carefully scale the boiler. In case of steady running scale the boiler 5 months after
the first starting-up. Then every 2-3 years depending on system specifications.
Periodically remove boiler mud.
For all these operations call a specialized centre.

7.5 PERIODIC CONTROLS
At least twice a year control the water loading quantity by means of a small capacity meter.
