Installation instructions
Restart the burner and check its stop automatically checking the pressure of
intervention on the gauge.
Burner restart is automatic when the pressure inside the generator has
dropped by the corresponding value of the set differential.
AT THIS POINT THE GENERATOR IS READY FOR OPERATION
GRADUALLY OPEN THE PRESSURE INTAKE VALVE IN OR-
DER TO GRADUALLY HEAT THE PIPES
- Operate the burner at minimum capacity
or, if this is not possible, cause frequent
stops to gradually warm the refractory
and obtain its "cooking".
- Adjust the tightness of the manhole and of all water and smoke
side gaskets.
- By means of the combined action of the two cocks and the
drain, "clean" the conduits of communication and the crystal
of the level indicator;
- Repeatedly drain the boiler bottom by rapidly opening the drain
valves to eliminate possible processing residues;
- Monitor the operation of the level adjustment and pressure reg-
ulation devices.
Recommendations for using the generator
on the first day of operation.
NOTE:
The "manhole" gasket is made from rein-
forced carbon fibre fabric with binder.
If carrying out a "cold" hydraulic test on the new
gasket, the water slowly filters through the gasket
itself.
The gasket must be vulcanised. During the subse-
quent generator start-up, reaching 100°C vaporis-
es the water soaking the gasket, "vulcanising" the
binder and thus ensuring the subsequent sealing
of the same.
