Is there any rule of thumb as to how far a water heater should be from a fuel fill for diesel? I know diesel does not give off combustible fumes like gas. Gas /electric waterheater. | ||

John, I'm sure there is a spec somewhere for diesel, and I don't know what it is. But the RV industry ANSI code, now under NFPA 58, lists no ignition point within 15 ft in all directions from a cylinder fill point for LPG. Granted, LPG vapors are more combustible than diesel in the presence of an ignition source. The point being 15 ft using diesel should be adequate if it is safe for LPG. I'm mounting all my flame sources on the opposite side of the bus from the fuel entrance, but if I end up in a fueling bay with gasoline and diesel pumps, I always turn off the ignition sources. I may be pumping diesel, but the guy next to me may be pumping gasoline. | ||

Chuck, Smart move. Another facter, when fueling, is wind speed and direction around the pumps. Jack | ||

" no ignition point within 15 ft in all directions from a cylinder fill point for LPG" What do mini motorhomes do? All the truck stops and gas stations have rows of pumps so even with the tank on the drivers side it will be near the next row of pumps. I think turning off the hot water heater when filling makes a lot of sence. Thinking about putting a lable buy the fill to remind me. But back to my question, it is not about the LPG tank or fill but the diesel fill. And the location of the hotwater heater that has a spark and flame. | ||

Modern appliance are pilotless. If your water heater is electric ignition, you can put a cutoff switch on the circuit that tells it to light, and flip that switch before pulling into a fuel stop (this is one more advantage to tankless water heaters -- they only light when you are using hot water). As far as how close your water heater can be to the fuel cap, figure on putting your propane tanks near the fuel cap, and the water heater as far from both of those as practical. If your heater has an "enclosed space mounting" option, you can draw your burn air from anywhere that you can run the intake hose. | ||

Easiest to keep it on the opposite side of te bus. Besides - do you want the heat coming out of the exhaust to get under an awning or close to the door? Glenn | ||

Diesel should not ignite from a nearby flame unless they have drastically changed the formula. Propane and gasoline are much more volatile and ignite from vapors. Jack, is that why firetrucks are diesel? |
