I have ready heater 150, 000 btu, the fan is blowing strong and there is constant fire comeing from sparkplug , but its not igniting. What could be wrong.
No fuel!! Several things can cause this, empty fuel tank, dirty fuel filter, plugged screen in the nozzle assembly,or plugged nozzle. So lets clean up the fuel system by first removing the top section of the heater and exposing the burner tray. Remove the tray and locate the fuel nozzle, remove the nozzle, now they say you can not clean them, I say with a q-tip, tooth pick and carb cleaner you can just be careful not to damage the nozzle. Behind the nozzle is a screen assembly these corrode at times so clean it up too. Below the nozzle assembly is the flame sensor, clean this with windex and a soft terry cloth rag, make sure it will have a clear unobstructed view of the flame.Put the nozzle assembly back together, and now inspect the fuel line for cracks, holes,and dry rot replace if necessary. Trace the lines down to the side where they come thru the case. Remove the side cover and locate the fuel line and in line filter, remove the filter. Cleaning this is easy you need a compressor and blow gun, all you do is blow air backwards thru the filter and instantly its clean. Inspect fuel lines and reassemble. Now make sure that you have clean fuel in your tank, and there is no water in it as well.Plug it in and you should now be heating like new. If not it could be your fuel pump!
