Ignites /starts will cut out after a few minutes
There are several reasons as to why this happens, and with that being said there are several things to correct this problem. I do this as preventative maintenance, remove the top section of the burner tube, this exposes the entire burner tray and internal parts. Locate the nozzle and remove it, they say you can not clean these, I say with a Q-tip, tooth pick and carb cleaner you can with out damaging it. Now behind the nozzle is a screen assembly these corrode at times so make sure to clean it as well.After cleaning up assemblies put the nozzle and filter screen back together.Next is the flame sensor, it is located below the nozzle assembly, round in shape and has a lens of sorts at the front. These collect carbon deposits, dirt, and the occasional homeless insect. It can be cleaned with a soft terry cloth rag and windex, now inspect the fuel lines for cracks, holes, or dry rot, replace if necessary. Locate the fuel pump next, on the back of it there is a foam air filter, this I clean with dawn dish soap rinse and dry really good, then put it back. Trace the fuel lines back to where they come thru the burner tube, now remove the side cover, you should see the fuel line and it goes to an in line filter. Remove the filter and I use a compressor and blow gun to clean it by blowing air backwards thru the filter, instantly clean. Inspect your lines again, replace if necessary. Replace side cover and open the fuel tank, lean the heater so the fuel runs towards the fuel filler opening. You are looking to see if water is in the tank, this happens from condensation when in storage. If there is I drain the fuel in to a clean five gallon bucket, now the fuel will float on top of the water and you should be able to see it.If there is water try to dry out the tank with a rag and remove as much water as you can. You can siphon off the fuel from the water and reuse it if you like just be careful not to siphon to far and get the water. Fill your heater with fuel, put cover back on the heater and plug it in, it should now fire up like new. Good luck
