Open the fuel supply line into a container while it's pumping (running) and trying to start. When the fuel begins to run clear (no bubbles), then close the fuel line and it will light if all is in order.

Why does my waste oil heater burner shut off after about 15-20 seconds of running?


Depends on if you have to manually reset the primary controller. You may have a bad CAD cell, primary controller, backdraft of exhaust, or high temperature limit tripping due to overheating from either a loose belt, bad blower motor or capacitor. If there is a fuel filter, that may also be somewhat stopped up.

I have a riello burner 40 it will fire and come to temp but wont refire, goes into lockout


My first guess would be that it sounds like a clogged oil filter, air in your fuel line, is piping overhead, or leak in a fitting or connection causing it to loose it's prime when running.

I have also seen primary controls that are faulty do this, watching the complete cycle of the run time will give you more clues as to when the control actually locks out. Does it lock out during the run cycle as the boiler reaches temp.? If so,check for oil line and suction issues as stated above.

If it locks out on start up after reaching boiler set temperature, if hitting reset right away burner doesn't start and lock out occurs with no motor engaging, check motor (Note: Some motors when HOT will not kick in when powered, but after they cool down naturally they start, motor shaft may also be bound up tight, replacement is necessary) if burner motor spins but does not fire, check for fuel flow to the nozzle, be sure oil is pumping to the nozzle, if it is, clean cad cell eye, and check transformer for spark, if all is good.. replace primary control.

Disclaimer:
Of course all this information is technical troubleshooting information and should be performed by a Licensed Technician, not knowing how to properly test for flame failure can cause injury, fire or worse! Consult a technician in your area if you are not proficient at oil burner repair!

I am having trouble getting my Dayton Portable Oil fired Heater Model # 2E218E to keep running.


May be the primary control if you already replaced the photocell. Make sure the photocell is in direct line of sight with the flame.

Can u clean a electric oil filled space heater.


Yes, you can clean it, but only the outside surfaces. To the best of my knowledge they are a sealed unit. Some soapy water and a wrung out rag followed by the same process with clean water should clean it just fine.

E-1 code were are the filters ? how long are the


In order to find the fuel and air filters you must first remove the top section of the heater tube, this is done by removing the six to eight 5/16" hex headed screws. Now once the top section has been removed you will have access to the fuel lines, they vary in length as to where they go so a simple measurement takes care of that situation. Filters are as follows, the air filter is at the back of the heater assembly, it is usually a foam filter and it is in the air pump ( black plastic pump). Then there are actually two different fuel filters, first one is a screen filter just behind the fuel nozzle. You have to remove the fuel nozzle and there is the screen filter, while you have the nozzle out you can clean it by using a blow gun and compressor to blow air thru the nozzle and make sure there is no blockages. The second is located under the side cover, so trace your fuel line down to where it comes thru the heater tube and again remove the 5/16" hex head screws to expose the fuel line. Now some have the filter right there in plain sight and some depending upon the year have it in a grommet in the fuel tank top.Again remove it and I clean it the same way with compressed air blowing backwards thru it as well. Make sure that you have tight fits on all fuel and air lines, make sure the nozzle is clean ,the screen filter is clean, and put the nozzle assembly back together. be careful not to damage the nozzle.While you have the heater down make sure to clean the flame sensor, for this I use windex and a soft terry cloth rag. Put the heater tube back together and you are ready to test.

I think the fuel pump on my beckett burner is clogged is there a way to clean it. Ive replaced the filters and get fuel to the burner but get no fuel up to the line feeding the nozzle


As you face the burner, mounted in the unit, the oil line feed in on the left side. There is a cap, held on by 4 7/16" bolts. Inder the cap, there is a screen. You would be best to get a screen kit, available from the same place you get your nozzle, as it will come with a new gasket.

Shut off the oil. Remove the four bolts, pull the old screen, clean the housing (I use rags and WD40) and re-asssemble. If is is really bad, you should remove the nozzle assembley and flush the oil line to the nozzle, as well.

THe oil filter, screen and nozzle should be replaced at least once a year.

My oil heater stop working and won't switch on when I hit the reset button. Less than a month ago I changed the oil filter and a technician came and change the therostat flame detector on the oil burner...


How bad was the filter? Could be a plugged or dirty nozzle. There is a small filter on the back side of the nozzle that might need to be cleaned.

Turn off the power switch. Loosen and pivot the ignition transformer out of the way. Remove the tube with the ignition electrodes and the fuel tube and nozzle. Remove the nozzle, clean, and follow these steps in reverse.

Hope this helps, good luck, and work safe!

Oil burner/waste oil heater not firing


Don't know what model Reznor Waste Oil heater you have but I happen to own a Reznor RA235. 235,000 BTU. If there is no oil being pumped up I would first check to see that the filter isn't clogged where the oil sucks up from the tank. There should be a gauge on yours with different color codes as to when the filter must be changed or cleaned. I already had to replace the pump on my Reznor RA235 as the pump went bad a couple of years ago. You can tell if it is pumping or not. There is also a filter built right outside of the pump on mine and one up on top of the unit that need to be cleaned at times. The manual shows all of this.

REDDY HEATER PRO 70


I have a Reddy Heater R100 that ran just fine until one day it

wouldn't ignite. I took the cover off to see if it was sparking and it

ran just fine with the cover off. I got on the Internet to see if there

was a definitive answer as to why it would only run with the cover off;

there wasn't. So I decided to troubleshoot it step by step instead of

replacing everything at once. You can thank me later.

Step 1: Dumped out old fuel, made sure the tank was completely dry and

clean. Put in fresh kerosene. This is an absolutely hideous job.

Result: Still would only burn with the cover off. Said bad words.

Step 2: Replaced all three filters. Result: Still would only burn with

the cover off. Didn't say bad words, just thought them.

Step 3: Removed the end filter cover and pushed on the pressure relief

ball. It seemed to be stuck.
so I marked the relief screw, counted the exact number of turns to take

it out, and washed the end filter cover and small parts with Dawn

dishwashing detergent. Harsh solvents can melt the plastic on the end

filter cover. Blew everthing dry. Put a little oil on the spring and

ball so they wouldn't rust. Put the relief screw, spring and ball

together, making sure I turned the screw back in the same number of

turns that I took it out with, within a tolerance of about 1/8 turn.

Result: Still would only burn with the cover off.

Step 3: Downloaded a manual from:

http://www.desatech.com/manuals.cgi?products=Construction%20Heaters to

find out the spark plug gap. They didn't have one for an R100 so I used

the one for a R100EDI. I cleaned and set the spark plug gap to .055".

I think later heaters use .075" or .085". Check your manual. Result:

Still would only burn with the cover off.

Step 4: Removed the nozzle. Put a clean paper towel under the input and

sprayed carburetor cleaner into the output end of the nozzle,

backflushing it. Four or five pieces of crud came out, onto the paper

towel. Really cleaned the nozzle good. Blew it off with compressed air

to make sure all of the carburetor cleaner was evaporated. Replaced the

nozzle. Result: O frabjous day! It worked just fine for about a half

hour, then it started coughing and smoking.

Step 5: Removed the nozzle again. Put a clean paper towel under the

input and sprayed carburetor cleaner into the output end of the nozzle,

backflushing it again. Four or five pieces of crud came out, onto the

paper towel, again. Really cleaned the nozzle good, again. Cleaned the

fuel filter and the upper fuel line. Made sure everything evaporated

before I put it back together. Result: works great with the cover on.

Ran the tank of fresh fuel empty. Put the original fuel back in, it

works too.

So, if in the future, I have the problem where it doesn't burn with the

cover on, I'm going to start with the nozzle, upper fuel line and fuel

filter.
