Are you out of fuel? If you're lucky, the oven will stop working after it is discovered. But, if it isn't, you can still fix it with a little effort. Ideally, you shouldn't need these skills, but it's better to know what to do in such a situation.
Steps
Step 1. Try pressing the reset button on the oven
If there are two copper lines on the stove, the pump should be running. If it still won't start, take a look inside. If oil does not splash, bleed the fuel line as described below. If fuel splashes, you have additional problems.
Step 2. Collect all the necessary tools
See below for “what you need”.
Step 3. Turn off the oven
To do this, there must be a toggle switch on the stove. If you have already pressed the reset button, you do not need to press it again.
Step 4. Locate the outlet valve
It is on the side of the fuel pump, usually at the clock position at position 4 or 8. The fuel pump is probably on the left side of the burner block. The outlet valve looks like an oiler with a nut-like hexagon. A wrench about 1 cm in size will help to install it.
Step 5. Attach nylon tubing to outlet valve ¼
The tube must be long enough to reach the bottom of a nearby container. A 1 L bottle will work and is generally large enough for most systems. This container will be used to collect fuel during purging in the next step. The tube is attached to the outlet valve, prepare it by loosening it with a wrench. Turning it counterclockwise will loosen it, similar to a bolt and nut. Then fasten lightly again. During this process, you may hear air gurgling from the tube - this is a good sign.
Step 6. You are now ready for the final step
while holding the tube in the container (or have someone else do it for you), turn on the oven and then quickly open the vent valve ½ turn. Fuel should flow through the tube. Let it sit for a few seconds (until the container is full) to make sure that air has passed through. It may be necessary to manually start the starting mechanism with the reset button, or attach another empty container (see Tips), especially if the tank is not very close to the burner. If you cannot get the contents of the outlet valve, this could indicate a problem with the pump, a clogged filter, or a damaged fuel line between the tank and pump (more on this below). If you used a clean, dry container, you can safely return the contents to the tank, otherwise, you need to think about what to do with it. If the container was not dry and clean, it is best not to add the contents back to the tank.
Step 7. Tighten the plug and the burner should work
If not, go back to step 6. You may need to try again.
Step 8. After the burner starts working well, air stops coming out of the pipe, pull back the vent valve a little
Do not overdo it.
Step 9. If several attempts to restart the burner fail, the reset button may be locked
To reset, hold down the reset button for 35 seconds and then release.
Step 10. If the oven does not start, you may need to clean the oil filter
Typically, it is a black canister with a red top, usually a built-in type. You need to loosen the bolt 1 cm until you hear air seeping. Tighten it back when the fuel starts to bubble.
Step 11. If the oven is still not working, the fuel supply lines may be damaged or shattered, or the filter itself may be clogged
Visually check the length of the fuel line between the tank and the stove. Proof of fuel leaks and line damage needs to be found. Replace them as needed. The shut-off valve between the tank and the filter must also be checked and, if necessary, replaced. A set of filters costs around $ 100, so if you open the filter housing, you need to change the filter material. Loosen the large top hex bolt while holding the bottom filter bowl. You may need to place a wrench on the bottom of the bowl to prevent the hex from turning if the top bolt is loose. After you loosen the bolt, fuel in the bowl may start dripping from the lower bolt, then place a container underneath. It's okay if the glass from the filter gets into the container, if it's large enough, and the fuel won't go anywhere. The filter consists of felt and metal mesh. It can slide off the bolt. Spare filters are supplied with replaceable seals and gaskets for the bowl, with bolts at the top and bottom. All gaskets must be replaced. Collect. Open the fuel valve and stop any leaks - they are especially likely around the bolted filter bowl (sometimes the fuel line may be blocked - contact your service technician). To stop leaks, wipe the filters and bowl.
Advice
- Fuel can be poured back into the tank.
- Consider using a paper filter before pouring fuel back into the tank.
- When the oven is running, you will hear a typical “roar”. When the oven is not working, you will not hear anything.
- Better to wear gloves.
- You can use "K1" kerosene. It is more expensive, but it works great.
- Never add gasoline to the burner oil tank.
- If you are using a plastic container to collect fuel, you should remove it as soon as possible. The oil will dissolve the plate and the container may perforate within a few hours!
- Diesel fuel can replace heavy fuel oil. They are nearly identical, but diesel is tagged to identify it for legal purposes. You can also use off-road diesel. If you use automotive diesel to heat your homes, fuel tax may be deductible for federal and state taxes.
- The process may seem rather boring, but all of this can be done calmly and without fuss.
- To ensure that the oven will operate normally, look for the orange light (fire) visible through the viewing window on the front of the oven.
- Depending on your stove, # 2 diesel can run as a last resort if you need oil right now. Depending on usage, you will need about 5 gallons of diesel for 1 day.
- Contact the fuel oil delivery company and inquire about the conditions for replacing the filter, as fuel supplies may have damaged the filter.
- In some countries, heating oil is colored red. There is no cause for concern.
- Quick tip: The easiest way to clear the fuel line is to use the brake line from the vacuum pump sold in many auto stores. Place the hose on the air outlet plug and swing the handle until the air comes out. It's faster and easier. No need to press the reset button, no need to worry about the burner suddenly blocking out. If this happens, you need to hold the reset button for 1-2 minutes. If you suspect that sediment has entered the oil wire, use a pump or compressor to return the sediment back to the reservoir.
- Liquid fuel should go through the wire after a while, then you make sure that no air gets there. The time depends on how powerfully and quickly the fuel is supplied. For a volume of about one cup, a wire of 1.8 m is needed.
Warnings
- Do not add gasoline to the oil tank.
-
If you notice that fuel is spilling onto the floor - STOP!
The combustion chamber is flooded and must be repaired first before attempting to start the burner.
-
Do not push too hard and often on the reset button.
Try pressing it once or twice. If the device does not start, it probably will not start if you hit the button even harder. You risk damaging the device.
- Make sure the wrench fits on the burner. Do not use excessive force when loosening or tightening the outlet valve. If you remove the vent valve, it won't be so easy to attach it back!
- If you decide to use diesel fuel temporarily, make sure you have enough. If the fuel runs out repeatedly and destroys the burner, the filters must be replaced or cleaned.
- You are dealing with fire and fuel, so be careful!
- If you decide to use diesel fuel temporarily, keep in mind that some diesel fuels are more flammable than standard # 2. It can lead to fire! Kerosene is a great fuel option. Oil heating system with kerosene will work 100% without any side effects. In this case, kerosene is mixed with liquid fuel, this lowers the temperature at which the fuel turns into a "gel" and no longer flows. This is called the "cloud point" and is reached at -9.5 degrees Celsius. Since the cloud point of kerosene is -42.7 degrees Celsius, 15% of kerosene in the mixture at -9.5 degrees will not yet turn into a gel. This makes it ideal for storing fuel in external tanks. The downside is the high cost.
- If you are not careful, you can hurt yourself. At the very least, be careful and wear gloves.

Not suitable for all burners.
This process only applies to some burners. If you are unsure, it is best to contact a qualified technician.
