Question about Heaters

1 Answer

Only half of the wicks burns/ flame varies in height/ smokes !

Looks like only the back side of the wick burns. I can't seem to adjust the flame height It's either too high or almost goes out, and when the flame is high enough to heat, it smokes like CRAZY !! Would appreciate ANY help. The heater has been used 1 season and has very few hours on it.

Sounds like you have a wick that has burnt unevenly in the past and now there is not a good setting for an optimum burn. Either the wick needs to be trimmed even or you need a new wick.

How do I get my furnace to stop smoking and make my burner flame turn blue


This is an oil heater with a wick, or an oil furnace?

Wick
If it smokes the wick is too high and the burner is not burning all the gases produced by the hot oil in the wick.

Use the wick trimming tool and then relight it. Light the wick and then lower the flame until it is blue.

Furnace
With a furnace, you need to open the front, clean out any soot and clean the spinner in the middle. You may need to regulate the air mix intake to get a blue flame. If it is yellow, you need more air.

If it's gas, you need an engineer.

Black smoke coming kerosene


hi dear,

First of all make sure that the heater is filled with K-1 Kerosene. Other fuel, such as gasoline, home heating oil, etc. do not burn hot, causing the heater to burn out of control. NEVER USE GASOLINE or any other fuel described as flammable. If there is any question about the fuel in your heater it is best to drain it and replace the wick and start with fresh K-1 Kerosene. If you are sure of your kerosene and your heater is giving off sooty black smoke it is a sign that the fuel/air mix is off. Make sure your heater is not in a draft. Too much air can create a very high flame condition. Avoid placing the heater in drafty areas or under a ceiling fan. Make sure the burner chimney is seated correctly. If the burner chimney didn't seat into place correctly after lighting you may be getting a very high flame on one side. If it's a high orange flame all the way around try rolling the wick adjuster knob down within the adjustment range - the wick may just be raised too high. If these things do not fix the problem wait until the heater is cool and inspect the burner cylinder. If there are any holes plugged with soot it needs to be cleaned, or if it's dented or buckled it needs to be replaced. After you have checked the fuel and burner you should check to make sure the wick is installed at the correct height. Refer to the owner's manual for exact wick height. If the wick is installed correctly and there is no other obvious defect it is best to take the heater to a service center to determine the cause.

Dyna glo RMC 95 C6 kerosene heater, BRAND NEW. Wick and flame seem very low. At Max the wick height is 3/8(suggested height by manufacturer), flame is quite low, and not very hot at all


1. Check to make sure you using fresh clean kerosene fuel. 2. Make sure you fill the heater and let it set for at least an hour, 2 hours is better. 3. If either of those solutions don't fix the problem, return to the store.
I have the same heater and just changed the wick. When working correctly, it should be so hot that it's uncomfortable to hold your hand 2 feet over it.

I have a 23-dk corona kerosene heater. it was smoking so i replaced the wick. after replacing the wick it still smokes heavy. how do i fix the problem.


Check all airvents into conbustion chamber. Make shure they are all clear of blockage. The heater needs air to burn fule properly. Check wick adjustment it may have to much wick.

My Dyna GLo kerosene heater has excessive smoke and yellow flame


I'm wondering the same
Should a duraheat, etc., cylindrical convetion heater's flame be bright yellow, blue , or what? With the old wick the flame was blue, with the catalytic converter glowing red hot. Now with the new wick, I can't even see the CC, because the flame burns a bright yellow. Also I have to really fine tune it now. A wee bit too high, I get smoke and soot. A wee bit too low, same...smoke and possibly flame out.

Burns unevenly and smokes


try emptying your heater of fuel,and lighting it letting burn for several hours. This will burn all of the deposits off of the wick. Make sure your heater is outside when you do this. when done lower the wick,fill with fuel,and let the wick soak for fifteen minutes before lighting.If this doesn't work try brushing the top of the wick a light brush of some sort and light.If still no luck,change the wick.

Dyna Glo 95-c flame height


check your air passages for a blockage. the wick just aids in burning your fire.
