In general if you have upgraded the house with new drywall, siding or other thermal products you have lost some air intake for the old drafty house. The solution to that is to install a damper door on the chimney close to the oil burner. This allows the chimney to intake air from the house to help move the exhaust gases up the chimney.
Also i would strongly suggest having the chimney checked for a birds nest or obstruction.
If you haven't made any home improvements i would suggest that you have a leaking fuel nozzle that is not igniting fuel right away and flooding the chamber.
Best suggestions is that if you can check the chimney and it's clear I recommend calling a service technician for proper repairs.

SOURCE: Fuel Oil Smell in House

With any internal combustion devise it needs oxygen to combust the fuel, I suspect that your house is sealed shut to keep out the cold.  I suggest that you raise a window slightly so as to cause a draft for the heater. Be sure that the raised window is not between people and the heater because the cold air will pass over them and they will get very chilled.
This is the same fix for smoking fireplaces.

SOURCE: My RCE 229A heater is filling the room with fumes.

Fumes are bad, stop using it until a technician has checked it out. Get a CO detector!

Oilfired furance proper operation


There are many, many different types of oil burners. The operations and safeties vary according to the use and the grade of the oil being burned. Some burners use a nozzle with a specific spray pattern. Some burn oil that drizzles into the bottom of a pot type heat exchanger. Some use safeties that are thermal, infrared, or ultra violet, and some use photo cells. They can be much more dangerous than a natural gas burner and require caution. Picture a grease fire, or the bricks burning away from your burning roof around your chimney, or the violent explosion of hot gasses inside your chimney flue pipe and furnace full of oil (kind of like a cannon). You might want to look for a tutorial link at an oil burner site preferably the manufacturer of your oil burner. Hope this helps and good luck.

Riello 40 burner giving off black smoke,new pump and nozel installed same problem?


Black smoke indicates a lean burn - meaning that the fuel to air ratio is to great for optimal combustion. This will cause a soot condition in the heat exchanger very quickly and drop efficiency. Too much air will make the burn to lean. The oil burner technician will do a smoke test and adjust the air intake damper on the burner motor as part of an annual tune up that includes setting the amount of carbon dioxide, excess air, stack temperature, draft and more. Doing so will provide the most efficient transfer of energy in the fuel to heat your building and prevent premature failure of the burner and furnace. To do this properly, you need the right test equipment - it can not done by "eyeballing" it.

Oil burner late ignition


I would check the spacing between the two probes. If they are too far apart they will not generate wnough heat to ignite the fuel. Or the porciline in the igniters could be cracked and grounding out sometimes, or the air fuel mixture could be off a bit, you may have to adjust the input air Good luck

How do I get wood stov in the Chimney?


With a wood stove or vent type chimney it is easy, just take a section of chimney out and insert the heater. With a brick chimney you may have room to put the heater in from inside the house. If not, lower the heater down the chimney.

ChimneyHeaters.com Chimney Heat Exchanger
Hi. I also have the toyo stove and that combined with one of these Heat exchangers will heat a 2000 sq/ft House to the point that you have to open the windows in winter.

I got mine at Chimneyheaters.com but I am sure there are of lots of places that have them.

Gas backup wont light. repairman said need new heat exchanger. approx 60 days ago replaced all burners and it woked ok they got it running for 1 night now it is out again. if the xchanger is bad why did...


I would only assume that now you have taken out an over heating sensor. When a heat exchanger goes bad it is a very dangerous situation because now you are pumping carbon monoxide in your house along with your heat. A heat exchanger is a baffle that hot gases pass thru, heating up the exchanger along the way and expelling carbon monoxide out the exhaust/chimney. Bad exchangers crack along seams or burn holes thru allowing the exhaust to mix with the blower air and in time this could cause carbon monoxide build up in your house. This cracking also lets hot exhaust in to the furnace and can burn up over heat protection, wiring and possibly cause a house fire. Please change out the heat exchanger or entire furnace, there is no price to replace a human life.

My Carrier LP furnace is cycling when zone 2 has two degree temperature difference. The system goes thru the start up process, lights the burner, starts the house fan, and then dies with an Event Message...


Your furnace has a minimum airflow required to keep the heat exchanger within the correct temperature range. Depending on the model, either your ECM fan motor circuitry is detecting inadequate airflow at high pressure, or the heat exchanger temp sensor is reading high.

Some zone systems have a "bypass damper" setup. This is a damper in a duct that connects from the supply plenum back to the return. It opens when smaller zones are running so the system fan can keep enough air moving through the exchanger.

Your bypass damper may be stuck or disconnected. Or, setup on your Carrier zone board may not have been done correctly. Another possibility is that your system turns out to need a bypass damper and your contractor didn't realize it and hadn't installed one.

If it used to work and this is a new problem, another possibility is your filter is not permitting enough airflow; or did you recently modify any ductwork that could have inadvertently restricted the airflow, even on the return side?

Last, verify that the Zone 2 damper opens fully when the call from that zone happens.

Good luck!

The fan limiting switch is acting up. It should stay running until lower temp is reached. It will cycle until the temp stays below or at the low setting. Limit switches are adjustable.

I just replaced the heat exchange unit. It ran ok for a while then after it got up to temperature and shut down it wouldn't turn on again by itself. Fumes. I took off the cover for the burner and could see...


Be careful opening combustion chamber with fumes present. The soot means the gas, or fuel to air mixture is incorrect. The inlet of the burner should have an adjustment that slides. That is an air coke . It may be closed or completly open. Adjust it to a blue flame. Close the combustion chamber when lighting.. If fumes build up, Ther is an explosion hazard when working on heaters. Any type . good luck

Intertherm furnace explosive burner ignition


Cheman, yes this is a real problem. Not only will it get worse, it could kill you and your family. If there is a blockage inside the heat exchanger where your technician could not reach, you would not do much better and may cause more problems if you do. If you continue to run this furnace, you will create Carbon Monoxide and it will kill you over a very short time.

Stick with yor technicians recommendation and get a replacement unit. Go with a direct vent unit and a higher efficiency than this old clunker.
