14. check the combustion as described in the preceding paragraph "Combustion test and adjustment"
on page 31 checking that the fan speed automatically change;
15. apply the label indicating the type of gas (provided with the kit) in the area provided on the “WARN-
ING” plate inside the boiler;
16. in the case of liquid gas fuel, it is important that the boiler be exclusively fuelled with commercial
Propane G31 and not with Butane G30. For this reason, we recommend that the supplier of the fuel
be informed, for example, by applying the sticker provided in the conversion kit on the gas tank or
in its immediate vicinity, so that it is visible to the employee at the time it is being filled.
Hydraulic settings (pump speed)
The pump has a selector which allows to reduce the
speed, so as to reduce the noise produced by the too
rapid circulation of the liquids in too small heating sys-
tems.
• III = Maximum Speed (Factory setting)
• II = Medium Speed
• I = Minimum Speed (use only if strictly neces -
sary; test the heating system, verifying that no
overheating problems occur).
Draining the heating system and the storage coil
When it is necessary to drain the heating system, proceed as described here below:
f
Connect a rubber pipe to the draining tap ter -
minal 1 ;
f
put the other end of the pipe in a suitable
drain or sink;
f
open the draining tap by turning the nut 2
counterclockwise, using a suitable spanner;
f
when the pressure is COMPLETELY drained,
it's possible to open the radiators venting
valves, to allow the air inlet. The complete
system drain is possible only draining the liq -
uid from the lowest point of the system itself.
f
when everything is over, close taps (turning
the nut 2 clockwise) and air vents.
In the primary exchanger a certain quan -
tity of water of the heating system remains. If you want to remove the boiler from the wall, we
advice you to close with plugs the hydraulic inlet/outlet heating system connections.
Draining the storage unit
f Close the hand valve installed on the boiler's cold water inlet connection;
f
connect a rubber pipe to the terminal of the storage draining tap 3 ;
f put the other end of the pipe in a suitable drain or sink;
f
open the draining tap by turning its hand nut counterclockwise;
