Special recommendations
Occasional (monthly) use of the device will increase reliability by purging old fuel.
If the device uses the same tank as the engine:
Observe the engine manufacturer’s recommendation with regard to the fuel type
and moisture removal.
If the device has a separate tank:
When selecting the fuel type, take note of the temperature limits of each particular
fuel.
Removal of the water from the tank
Isopropanol based anti ice detergent meant for gasoline cars (no ethylene or
methyl based) will be added to the fuel during the season. It is useful to make the
addition after each couple of tanks and in the beginning and end of the heating
season. The anti ice detergent binds the condensed water and prevents the sedi-
ment and contamination during the summer. For the dosage, observe the recom-
mendations given by the manufacturer of the agent.
Winter storage
If the device uses the same tank as the engine:
• Change the fuel
fi
lter.
• Perform measures recommended by the boat/engine manufacturer to
be performed before winter storage.
If the device has a separate tank:
• Drain the fuel tank in the autumn.
• Clean the tank and change the fuel
fi
lter.
• Fill the fuel tank with fresh and clean fuel in the spring.
For the device itself, you do not need to do anything.

An anti-freezing agent for diesel vehicles may increase the forming
of scale at the bottom of the burner and therefore shorten the mainte-
nance interval.
