DESCRIPTION OF THE APPLIANCE
The steel boiler from the SUPERAC range is a high performance generator for
heating systems up to 90°C. When combined with a hot water tank, this
generator can be used also for the production of domestic hot water.
This is a en-bloc pressurized combustion flame-inversion boiler. The flame
produced by the burner develops into the furnace and as it is closed on the
bottom, the fluegas returns to the anterior part, and through the cavity
obtained in the front door insulation it enters into the tube system.
Here the flugas is obliged to make a whirling run through the turbolators,
which increase the convective heat transfer.
In this way it obtains the maximum absorption of heat without harmful
thermal stresses and above all it has a useful output superior to 90%.
After the tube system, the fluegas is collected in the smoke chamber and
conveyed to the chimney.
The boiler can be equipped with all the traditional liquid or gaseous burners.
The burner is installed on a hinge door; in this way the regulation and
maintenace operation of the boiler and of the burner are facilitate, it is not
necessary to disassemble the burner.
The thermal insulation of the boiler body is obtained by applying a pad of
highly insulating mineral wall.
Elegant pre-painted steel panels complete the outside finish
The pre-wired control panel for the boiler automatic operation is positioned
on top of the boiler itself.
The electrical diagram is housed inside the control panel.
An electronic climate adjusting system can be installed on request and
provides the boiler temperature adjustment as well as many other auxiliary
functions.
CHECKS AFTER BOILER CLEANING OPERATIONS
After performing maintenance and cleaning operations, repeat the preliminary
start up inspection (see page 23), check the burner calibration and perform a
smoke analysis to ensure that the correct degree has been reached.
Check the seal of the fuel supply system. This inspection is absolutely
necessary when gaseous fuels are used.
Check the perfect seal of the smoke circuit and, if needed, replace worn seals.
Check the seal of the pipe system to avoid time-wasting water changes and
refilling which could also increase the risk of scaling.
Should the boiler inside walls be scaled, a chemical washing is needed to
remove scale. This operation must be performed by qualified companies.
The specification of the plant water should be examined and, if needed, a
treatmen system should be installed.
Never leave highly inflammable substance containers in the premises where the
boiler has been installed.
TROUBLESHOOTING
Below is the description of the most common faults and their remedy:
FAULT: the burner does not turn on.
REMEDY:
-
check electric connections;
- check the regular fuel supply;
- check the integrity and the cleanness of the fuel supply system and that
no air is present;
- check that ignition sparks form regularly and the burner appliance works
correctly;
- check the boiler safety thermostat intervention with manual reset;
- check the calibration of the environment thermostat.
