Have master heater 200000 btu that has spark an fuel but will not fire can someone help me

If this is a fuel oil burner in a residential style forced air furnace, you probably have the electrode adjustment wrong. The generic measurements for the electrodes for an 80 degree hollow fuel flow atomized mist spray is 9/16" above the center of the nozzle, 1/8" gap, with a leading dimension of 1/8". Because the atomized mist leaves the nozzle at an 80 degree angle, electrodes protruding too far out will be drowned out by the fuel and not ignite. Electrodes not extending out far enough may cause a serious delayed ignition that will rock the structure, or not light at all because if the cad cell doesn't react to the UV rays of a flame, it locks out the ignition control.

When in doubt, its always back to basics first. If this is a torpedo style heater, it may or may not utilize the two electrodes for ignition as noted above and may just use a spark plug style ignition device, in which case the above dimensions are rendered useless.

How does circuit breaker work?

In the circuit breaker there are two electrodes with space some distance.
There are many types of circuit breaker air blast,oil C.B, vacuum C.B etc.
Most probably oil circuit breaker is used. In the OCB, the transformer oil fill.
And these electrodes are submerge.
Now when the electricity flows from one terminal to another terminal, the arc is developed between terminals end inside the circuit breaker. This arc is quenched by transformer oil.And the electricity flows without any fault.

Beckett burner adjustment

that's really not a question. do you need to adjust a burner or an electrode? the question that is not a question is not clear. my 6 year old can write with complete sentences.

adjusting a grill burner is usually a process of adjusting the gas flow through the orifice and adjusting the air shutter that allows oxygen to mix with gas as gas flows into the burner. The only other adjustment that affects the burner is not always on every control valve but if it is there, look down inside the valve stem. If there is a tiny flat-head screw there that is an adjustment for gas flowing through the control valve. The orifice, air-shutter, valve stem adjustment is all there is but that is a tremendous amount of control for a simple gas burner that is a solid material with no moving parts.

if the question is adjusting the electrode, an electrode is only a miniature spark plug. the only adjustment is setting the gap. aside from that we can make sure the ground is clean and connected tight, make sure the power source is strong and make sure the tip of the electrode and where ever it will spark is clean. One well-placed drop of grease will foul an electrode so the grease needs to be cleaned from the tip and from aound the tip for a spark to have a clean place to arc against.

My oil furnace has a strong smell of oil when it runs,what can i do?

PLEASE call a serviceperson,but, it sounds to me like your furnace is burning dirty and needs the electrodes cleaned or replaced as well as the proper oil nozzle and filter hope this helps you out, OH, one more possibillity is the furnace or flue chimney could be stopped up or the air mixture is not set properly on the burner. ANY OR ALL OF THESE COULD CAUSE CARBON MONOXIDE POISONING C/M IS ODERLESS AND COLOROUS AND CAN KILL YOU QUICKLY. CALL A REPUTABLE SERVICE PERSON PLEASE!!!!!!!!

5 burner gas Vicking stove top keeps clicking after is on


Their are 2 possible reasons the igniters would continue to click after the burner is lit.

1) the burner is slightly dirty and the part of it very near the electrode is not burning correctly so the igniter doesn't think the burner is lit so it will not tell the spark to turn off. It could be cleaned by using steel wool and cleaning the burner holes near where the electrode is and then use a paper clip and poke through the holes on the burner to clear them so they burn correctly.

2) the electrode (the spark plug at the burner) is cracked so even though the burner is lit so the electrode can not sense that the burner is lit and wont tell the spark to turn off,so if having cleaned burner it still clicks after burner is lit the electrodes would need to be replaced.

The furnace wont stay running. there is adequate feul

I'm guessing you have an oil burner because of the "Adequate Fuel" statement. If so, be VERY careful while following this suggestion, OK? There should be a small inspection hatch on the front above the burner. Be sure everything is turned off and the fire is NOT still burning in the combustion chamber. Use a flash light and look in the inspection hole. If you can't see the end of the burner, use a mirror. If there is oil sitting in the bottom of the chamber, don't fire it. If you can see the end of the burner, it will look something like the picture. What usually happens is the nozzle partially plugs and the spray pattern goes a little goofy. As a result, the oil does not burn completely. Some will build up on the bottom of the chamber, some will create a lot of smoke and some will harden on or around the electrodes. All you can really do is check for unburned oil in the chamber and see if the electrodes are shorted with carbon. If you see a carbon arch on the electrodes, you can VERY gently remove it for a quick fix. If a lot of oil has built up in the chamber, the fire will continue to burn when the thermostat is satisfied and shuts off the burner. I have seen flu pipes red hot from this so be careful in deciding to re-fire it. There are several CRITICAL adjustments that require special tools to accomplish. Regardless of how things work out, you need a service tech. who knows what he is doing. BE CAREFUL! Sorry, my picture is too large. Just go slow and look it all over. If you are not in an emergency situation, call a service guy.

Rheem Highboy Oil Furnace runs, then shuts down. I throw in a lit paper to burn off oil residual from failed start. Hit 'Reset' button and furnace starts up. It may start up by itself for the next 3...

Oil furnaces have certain items that routinely go bad or need adjusted to work properly.Some of the common things are nozzle, then gap and location of the igniter,then last is the fire eye. You can see all of these items by pulling the burner tray out. The nozzle delivers the fuel in two ways more or less, first is spray angle then second is the rate or GPH. Nozzles are to spray an atomized mist this means no heavy droplets of fuel. If you have large drops of oil chances are a new nozzle can help you out, please pay attention to spray angle and GPH. The igniter is next, after time they will wear and you can clean the rods and reset the gap to specified distance, that being said it also needs to be a certain distance from the atomized fuel to ignite properly all very important. Then last is the fire eye it tells the furnace that a flame is established and to deliver fuel or flame out and shuts fuel down. These will build carbon deposits at times so simply clean off the deposit and clean the lens with a soft cloth and windex reposition put the burner tray back in hook up the fuel line and off you go.

Flame sputters

Hey welcome to the world of oil burner service!! :-) Theyare a finnicky beast to say the least. The problem you are having sounds like an air mixture problem. A combustion analyser would be the best tool to have but being that you probably don't have that try this. On the left side of the burner as you are looking at it is an air adjust ment ring and a fine tuning ring. the fine tuning ring is probably all you need to adjust. There is a screw that is usually right behind or near the pipe coming out of the pump and going into the burner. Loosen that and turn the ring away from you just a bit to close off some of the air and you will be fine. The burner is running a bit to lean. If you can see the flame turn the adjustment closed just until the flame color turns from a almost white color to a slightly orange color. Then you should be fine. Good luck!!

Burner will not light

you need to tell me what the burner is doing when it starts up. Some basics to look for:
1- bleed pump of any air- is it a new install? 2- If you are getting fuel, are you getting spark on the electrodes? 3- if you are, you may need to adjust draw assembly air, and or air intake per Carlin specs.
