The heater has sat for approx. 2 years. when last used it worked fine. when i plug it in the spark plug fires and sometimes it will ignite for a few seconds an then shut down. the spark plug also quits fireing. if i stick a small propane torch by the nozzle it will run longer. is it poosible that the fuel is to old and causing this problem.

Re: reddy kerosine space heater
Bucklehead...I assume you discarded the 2 year old fuel... if not do so. Your fuel delivery problem could be caused by a number of things. 1. Incorrect air pump pressure, 2. worn or restricted nozzle, 3. deteriorated fuel line or air line, which in turn is creating the ignition problem, 4. the spark plug is bad OR you may not have a fuel delivery problem at all - just a photocell that has gone bad or has a wasp nest built betweem the eye and the flame (check this first). If the photocell can't see the flame it will shut the heater down. That's it's only job. More troubleshooting tips

Well this one is trying to detect flame, please try checking the fire eye clean the lens with windex and a terry cloth rag and try to fire it up. Make sure that this eye has an unobstructed view to the flame, not a correct thing to do but jump the eye out and see if you run longer if so replace the fire eye.
Make sure the fuel is not contaminated,and is k 1 ,if it is diesel fuel in it,and it is not made for diesel ,then that is the problem,also use a anti gel additive for gelling in the fuel,it doesn`t have to be that cool for gelling.
It may be the spark plug (or the ignition module). On my Reddy Heater 50K BTU, there are six metal screws that join the top of torpedo tube to the bottom. Remove these,and the top of the tube casing. The spark plug should be in plain sight.
Turn the unit on and look for spark. If it's not firing, replace the plug. If it still doesn't fire, you may need to replace the ignition module (it's what is "connected to the spark plug via the fat ignition wire.")
make sure the high voltage lead to the sparkplug isn't touching anything metal on its way to the plug. the clicking may be the high voltage discharging to a metal part, not the plug. those wires age during use.
the kerosine heater uses a spark plug for ignition and a photocell to detect flame. at the back end of the blower motor is an air compressor. it is a vane and diaphragm compressor that supposed to put out 3.6 psi of air to the fuel nozzle. the fuel nozzle is a venturi type that creates a vacuum across the orifice to suck fuel from the tank. try this site for spare parts www dot desatech dot com. its the same place I get parts for repairing heaters.
