help needed, Airtronic diesel heater won't ignite

I would add kero to kill algae

If it has been sitting for 6 months check that mudwasps/spiders etc haven't blocked intake and/or exhaust.
We have left ours for nearly nine months and it fired straight up on the diesel left in the tank. I wouldn't add anything to the fuel.
Also check the battery voltage under load as they won't start if the power is too low.

Hi Bush camper,

I have a wabasto so I guess much the same. I have had two occasions where it has been idle for up to two years (sad I know). I have not had to add anything to the diesel and it has started with just a little fuss. Last caravan show I fronted the Wabasto dealer at the show to check if adding anything would be wise and he said not to do that. So I'm not sure as he suggested that the burner would be over heated and that the only fix was a clean of the lines if they had been blocked by algae growth.

I would suggest to have a really good look at the fuel lines as a starting point.

Kind regards
