Used Webasto Burner



This burner has a brand new motor installed.  Unit is currently setup for use in Hydro-Hot with hour meter.  If you have a different model, I can modify it to match your existing unit.


It may or may not need additional parts.  I do not have a way to run it for testing purposes.  No warranty is offered.  Burner is as-is and returns are not accepted.


You will need to install a new nozzle prior to use.
