I have a all pro R60A that turns on but shuts right off and blows tons of smoke out after shutting off.

These heaters have several things that happen to them while in storage. I do a yearly check on mine and it goes like this. Open the fuel tank and tilt the heater to see fuel at the filler hole, look at the fuel and tank you are looking for any water in the tank. Condensation is usually the culprit, what I do is drain the tank in to a clean five gallon bucket and the fuel floats on top of the water. If you see water use a rag and try to dry out the tank as best as you can. You can also siphon off the fuel for reuse just be careful not to siphon to much and get the water again. Next remove the top section of the heater tube, this exposes all of the internal burner parts. Locate the burner tray and remove it so you can access the fuel nozzle. Remove the nozzle, they say you cannot clean these but I say different. You need a Q-tip, tooth pick and carb cleaner and clean it up carefully so you do not damage the nozzle. Behind the nozzle is a screen these like to corrode so clean it real good too. Put the nozzle assembly back together, inspect your fuel lines for cracks, dry rot or holes and replace if necessary. At the bottom of the assembly there is a sensor for flame these collect carbon deposits,dirt and the occasional homeless insect. Clean this with windex and a soft terry cloth rag. Put the burner tray back together. Trace the fuel lines back to where they come thru the heater tube and now remove the side cover. You will find the fuel line and an in line filter remove the filter and clean this with a compressor and blow gun by blowing air backwards thru the filter. This instantly cleans the filter, now put it back together after inspecting the fuel lines,and replacing it if necessary. Put the side cover back on and go to the fuel/ air pump on the back of this there should be an air filter usually foam, clean this with dawn dish soap and dry really good before putting it back in.Inspect and clean igniter while you are inside the heater, then put the top section back together. Now you are ready to plug your heater back in and test it. If all went well you should be heating like it did when it was new. Just a tip for you is to look at the fuel coming out the nozzle it should be a fog not droplets, if droplets your nozzle needs changed. Pay attention to spray angle and GPH rating very very important.
