Gas Heater fuel adjustment

Post by dadnova » Sun Jan 31, 2016 6:27 pm

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.

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.
