Prior to the final assembly, I always like to fire up this type of stove before it goes in the box. Some of the older Coleman stoves are built so that the burner assembly and fuel tank can be removed in 1 operating unit. By firing it up now, it prevents any potential flaming drips on the new paint, and a fire is much easier to deal with when it's not in the box.
This stove has what is called the "hot blast" for pre-heating. What you do is to crack the valve a bit when the gennie is in the pre-heat position and dribble a bit of fuel in the cup. Light the cup, when it starts to burn down, crack the valve and feed the fire and it will start to turn to a nice blue flame. The more you crack it, the more heat you put into the gennie. You can actually make it "roar". Once pre-heated, they say you can just rock it back into the burn position while running, but I close it down and reposition it, then relight it. I was pleased, lit first time, no leaks and operated like it should. I'll do a 2nd clean on the burners as it loosened some scale on them and the burn wasn't as even as I would like. I may also have the inner iron ring out of position.
The guy that had the decals seems to have dropped off the planet, so I may cut my own stencil and paint the tank on it. They had either the water slide decal or the stencil treatment. For an 84 year old stove, I'm happy with how it's going to turn out. I think the older ones from the 20's put out more BTU's than the newer ones, but I have no real proof....could do a water boil experiment I guess. Doug
