Those things can be finicky when the viscosity of fuel changes. I would guess that the viscosity of a bio-fuel would change more than diesel with thermal fluctuations.
Maybe a second fuel system with a bio-fuel tank inside ( but not near the heater ) so that its viscosity remains more constant and you can light and shut down your stove with diesel utilizing the pre-existing fuel system.
You're making use of a lot of BTUs, what are you heating a cabin or a live aboard?
