The heater H
2
O / boiler Compact can be supplied with a
” Kit for the production of instant domestic hot water” (see par. 4.7) . When a tap is
turned on, the “ flow switch” commands the “ diverting valve” to convey the hot water
from the boiler to the plate heat exchanger .
The temperature of the domestic hot water obtained in this way is roughly 10° - 15°
lower than the temperature in the boiler as indicated on the handheld radio control and
in any case within the limits indicated in par. 2.
Hot water is not available when the
boiler is switched off. When the boiler switched on, upon a request for hot
water, it operates at the maximum steady state level of combustion: the
diverting valve only conveys the water to the plate heat exchanger if the
temperature in the boiler is above 61°.
The manufacturer recommends installing a
water softener to ensure an optimal life of the plate heat exchanger (see par. 4.7). It is
also advisable to regularly clean and check the plate heat exchanger. The Kit for the
production of instant domestic hot water comprises:
- 2 Gaskets.
- 1 Hot water delivery tube to the heating system.
- 1 Flow switch cable.
- 1 Diverting valve cable.
- 1 Complete Unit, preassembled, consisting of a plate heat exchanger, heating system
inlet tap, diverting valve, flow switch, brass delivery body, brass return body.
-2 screws for fastening the unit.
-1 complete locking band .

Installation of the “ Kit for the production of instant
domestic hot water” must be made as indicated below:
- Empty the boiler completely by acting on the “drain
tap” and empty or shut off the system.
-Remove the ring nut from the “delivery tube to heating
system (type 1)”.
-Remove, by acting on the indicated screws, the
“bottom back plate” and the “complete preassembled
unit support”.
-Next remove the “delivery tube to heating system
(type 1) “ fastened to the boiler.
-Fasten the “ locking band “ as indicated.
-Fasten the “ delivery tube to heating system (type 2) “
with the corresponding gasket.
-Connect the “ complete preassembled unit” to the “
delivery tube to heating system and to the circulating
pump of the boiler with the corresponding gaskets.
-Next fasten the “preassembled unit support” with the
corresponding screws.
-Firmly fasten the “complete preassembled unit” with
the “screws for mounting the complete preassembled
unit “ to the “complete preassembled unit support”.
-Lastly fasten the “bottom back plate”.
-Then make the hydraulic connections between the
heater / boiler and the system and fill up with water.
