Please refer to the Fluids section for complete information.
WATER BOILER
A water boiler can be connected to the engine coolant
circuit. If the boiler is located above the engine, an
additional recovery tank must be installed above the
boiler. Ducts to the boiler must be in accordance with
high temperature and high pressure. Never attempt to
use flexible hoses supplied from a hardware store.
A specic boiler kit is available from Nanni Industries.
Please contact your nearest Nanni representative
for more information. The amount of coolant must
be adapted depending the model of water boiler to
completely ll the coolant system.
COOLANT EXPANSION
When the engine is running, the internal temperature is
high ; as a result, the coolant liquid expands its volume.
The heat exchanger is designed to accomodate this
normal and physical expansion.
Make sure not to overll the heat exchanger when lling
with coolant.
COOLANT LEVEL
DANGER !
Never open the coolant lling cap or any plug of the
cooling system when the engine is operating or still

potential injuries !
Check the coolant level before starting the engine.
