To fill the system is necessary to provide a loading
tap on the heating circuit, or use the optional
accessories.
The boiler is equipped with its own drain valve,
the position of which is indicated in the figure to
par 2.2. This tap can never be used for emptying
the system, since all the dirt present in the circuit
could be accumulate in the boiler, compromising
the proper functioning.
The system must be equipped with its own
drain valve, with a size suitable to the capacity
of the system.
Pressure in the mains supply must be between
0.5 and 6 bar (In case of higher pressure a pres-
sure reducer it must be installed)
Attention!
Do not mix the heating water with incorrect
concentrations of antifreeze or anti-corrosion
substances! This could damage the gaskets
and cause noise during operation.
Unical will not be held liable for damage to
persons, animals or objects due to failure to
comply with the above instruction.
Condensation drain
The boiler, during the combustion process, produces conden-
sation that, through pipe “A”, flows into the trap.
The condensation that forms inside the boiler flows into a suitable
drain via pipe “B”.
Danger!
Before commissioning the appliance:
- check that the trap is assembled
properly
- fill the trap and check that
the condensation is drained properly
If the appliance is used with an empty condensa-
tion drain trap, there is an intoxication hazard due
to the release of exhaust gasses.
Condensation outlet, pipe to be connected to the drain-
age system
The connection between the appliance and the do-
mestic waste system must be made in compliance
with the specific reference standards.
