Oil furnace won't light - US - JustAnswerOil furnace will not light, - Gray furnaceman furnace
We built a wasteoilheater using an old 100 lbs.A cylinder of propane.The USFiltermaxx You Tube Channel will soon have a video on construction.
The trials and errors began after it was constructed.I'm going to let you know that these wasteoilheaters are great for winter.
Once you learn how to operate them, they are trouble-free.Why won't it light?
3.Your oil is dirty.I am amazed at what these heaters will do.We put oil in our house.It had some anti-freeze in it, yet it fired up and burned itself out for hours.The pick-up tube that feeds the flame will become blocked if your oil is dirty.There was no fuel or ignition.If this isn't corrected, you should settle your oil for at least 10 days prior to use.The dirt and water settles at the bottom of the tank, so don't draw your oil there.Take it up from the bottom of the tank.Higher is better.When the burner is off you can spray a cleaner into the intake tube to clear it.
4.The air pressure is too high or too low.I didn't understand it.I had good fuel.The igniter was fine.Design is perfect.The air was moving.There was no spark.We connected the shop air hose to the waste oil burner because it comes with its own air pump.We blew out the flame before it caught because the pressure was too high.If your air pressure is too low, you won't get ignition.To correct this, you need your air pressure to be around 5 to 7 PSI.
5.There is water in your oil.The oil burns well.Not a lot of water.The first clue will be bubbles and steam coming out of the tank.The next clue will be the oil/water boiling over the top of the tank and spilling onto the ground.It will not light.This is corrected by centrifuging the oil prior to use for a clean burn.
6.Your fuel isn't hot enough.The oil temperature can be adjusted with a dial on the outside of the oil tank.The temperature at which the oil should ignite is between 100 and 120 degrees Celsius.Increasing the temperature of the oil will solve many lighting issues.
7.The nozzle was coking.The heat from the furnace can cause the oil to produce something called carbon or coke.Particles in oil can cause a problem.Post flame-out fixes are more difficult to affect than preventative maintenance.The nozzle will be open and unobstructed if a weekly check is done.
There are 8.There is insufficient fuel supply.Make sure you have enough oil for your burn.The oil pump will seize if it runs dry.
The furnace will burn about 1/3 of a gal of oil in an hour for every 100,000 BTUs.1.5 gallons of oil is required for every hour of run time.
It's water in the oil, I thought it was air, but it can be very serious as the float gets swamped and then drops like a stone.If you don't have a return line to the tank, your burner is in the roof.The car engine oil works well at 80 to 90c.
Bryan was glad to help.I would get a tank return line.It's very important.You will be swimming in oil if the float sticks.You can't tell if it's in oil or antifreeze.It is difficult to get it out without a machine.I would look for a better source of oil.Thank you for your feedback!We like comments and good information.USFILTERMAXX
