14. Starting the Heater for the First Time

After you have installed the heater, bleed the fuel supply system carefully.
NOTE:
As a result of the low fuel consumption the heater must be switched on several times to fill the fuel line and prime the
system.
Conduct a trial of the heater to check all the connections for leaks and to ensure that they are secure. If the heater
suffers a fault during operation, the fault must be located and remedied.
