Gas Heater fuel adjustment

[dadnova]

My heater smokes quit a bit, can someone tell me how to adjust the fuel amount or where it should be set at?
Thought I would ask before I start playing with it.

Smokes through the exhaust or interior?

Mine always has a lot of exhaust smoke - its diesel

It smokes through the exhaust pipe, but the smoke can then enter.
It should not smoke that much.

[dadnova]

Or does it need to be removed and just cleaned and rebuilt?

Does anyone know?

I don't know what adjustments are available for the BN4 heater itself; you may have to adjust the fuel pump for less fuel flow. Mine never had even a hint of smoke when it was running, but I've not run it in many years now - I know that it drips gas and I haven't bothered to mess with it.

Did you ever solve the smoke problem? I am dealing with it now. Don't know how to adjust the mixture if it is possible.

I suspect the dosage pump may not be operating correctly.

Mine put out black smoke I adjusted the screw, from your picture on the far left, turn it out if possible. I reduces the spring tension on the diaphragm. Mine went from black to clean, but my screw was all the way in?? That way when I bought the Rig.
