Apparently of 1930's vintage. Probably weighs in at around 30 pounds so it's not a lightweight. Found in the "wild" stored underneath someone's outside staircase. Exposed to the elements for a few months until it was decided that it had to go. Original paint suffered a bit because of that but all in all a real solid survivor. Was told by the PO that it had been in working condition when placed outside. Checked it over and had fuel in the tank and everything looked good so struck the match and followed the light up procedure on the tag inside the front cover and viola...it makes heat! Two of the radiants are broken on the bottom so not sure if I can do anything with them yet but burns and looks good. It really does put out some heat. Alex As found. At home. I sure hope it's all there as I'd imagine parts are probably made of unobtainium. lol Fuel tank INSTANT-LITE STARTER valve and main FUEL SHUT OFF valve. Fuel tank gauge. HOT BLAST CUP. Heater has the hot blast feature for preheating the large generator. Much like the feature used on the early Coleman stoves. It makes for an exciting light up. Pump tank up to the correct operating pressure as on gauge. Light a match and place near the hot blast cup and open the INSTANT-LITE STARTER valve and the generator preheat ignites. Sounds like a small rocket engine. I hope it all goes as planned! lol Was told by a knowledgeable person that it came equipped with a THERMO-SAFETY generator that will not allow fuel to pass unless the generator has been preheated for the required time. On the start up procedure it says preheat for 1- 1 1/2 minutes before opening the main FUEL VALVE. Heater burners as well as the three generator heater burners on the side of the casting facing the generator will now ignite. Heater flame can be controlled by turning the regulating valve in or out. When the heater appears to be burning with a nice blue flame close the INSTANT-LITE STARTER valve. Burning without the radiants in place. Front cover open. Burning with only 6 radiants in place. Front cover closed. In the dark. I think it looks pretty cool and yes it does put out some good heat.
