I am running 60% Bio-Diesel; so it sounds like any combo of bio will work on the heater also?
It should indeed. Right now we mix about 10% petroleum diesel in our heater tank, but i see no reason why b100 wouldn't work as well.
Is it OK to use algae preventer in the fuel that goes into the heater? If it is I will plumb a line from the exit of the Racor filter over to the heater's tank. That way I can refill without any fuel spillage and keep the tank in a location that is not near the heater.
I can't see any reason why not. I don't use anything of the sort really, but i only carry about 40lt of fuel in the main tank, and i've never had a problem with algae.
It sounds like I will need to install a guard around the exhaust pipe to prevent hands from getting burned on it.
That's a good idea... on my list of things to do. I've leaned on it once or twice and was quite unhappy afterwards
How do you control the flow of fuel to the heater? There is a small hex fitting beneath the burner; is that the needle valve or do you need a needle valve in-line from the tank?
My force10 has a little regulator unit where the fuel comes in. It's got a knob with the hex nut in the middle. The hex nut is used to adjust the fuel/air mixture, and the knob the flow of fuel. If your unit does not come with this little device, i beleive you can buy them aftermarket, and i recommend it.
When you de-pressurize the tank you just bleed it from the tank valve? How do you vent the vapours and is this an explosion concern if there is a source of flame? I don't like the idea of venting it to the cabin when I shut it down; but the instructions on the tank say to release the pressure when not in use. Do you do this?
I don't have a pressure tank really, so i can't give you any good advice here. I try to keep all the pressure out of the system (i'd rather have it stove go out than not go out), and every couple uses i open the tank to equalize the pressure that has built up.
I wouldn't worry too much about the diesel fumes, because again they are not really all that flammable when things are cool. That said, i don't like the idea of venting into the cabin either... but i do think the system should be vented after use.. my stove was lit (i had thought it out, and turned off the regulator) for a week once without my knowing as the pressure was high... i was not on the boat. That could have been an expensive lesson.
