Initial start-up

After you have installed the heater, bleed the fuel supply system carefully.
NOTE
If the fuel lines are long, it may be necessary to switch on several times in
order to fill the fuel line to the heater.
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.
