Are flames meant to have orange in them when a gas boiler is on?

Answer 1

Yellow or orange in the flame indicates combustion is not complete due to lack of air. This can cause soot to build up on the heat exchanger reducing its efficiency. Worse, it can also cause the creation of carbon monoxide, which can be deadly if it seeps into the home. Therefore it is important to keep gas combustion equipment well maintained and tuned-up.

Answer 2

Your flame should be blue. Sometimes while viewing the flames some dirt or dust can be drawn into the flame causing it to burn orange. If you are seeing a blue flame with some orange or are getting the orange flame when you disturb the dust around the flame this is normal and expectable. If it is burning orange without any disruption of the dirt, you need to give the burner and venturi tube and air mixing chamber and shutter and the surrounding area a good cleaning out. Get out the shop vac and give it a good cleaning. Check the flue and the base of the chimney out as well while you are at it.

Answer 3

No Sarah. Flames should be blue. If orange there's a potentially serious problem. Call the gas board as a matter of urgency.

Answer 4

first of all mermiliz is faulty! at the same time as adjusting the shutters on the burners of a boiler, choking the shutter closed (or airborne dirt and mud in the openings) will reason a yellow flame by using lack of combustion air. beginning the shutters will enable extra air into the burner for perfect combustion. Like sensible cleansing airborne dirt and mud-balls out of the burner openings supplies a similar end outcome. different factors might want to reason a similar subject. lack of combustion air might want to reason a yellow flame. A clogged chimney or unsuitable venting might want to reason a yellow flame. a good room or the boiler being positioned in a small constrained section like a closet with filthy louvered doors on it or no "makeup air" might want to reason a similar subject. In any of those situations you would possibly want to work out flame "roll-out" which will be a extra severe carbon monoxide or perhaps hearth possibility. you actually must have this appeared at by technique of a respected and qualified boiler guy.

Answer 5

No. The blue flame means that the apparatus is working at its best. Orange flames mean that the flame is not as hot as it should be - and needs to be adjusted.

Answer 6

No. An orange/yellow flame indicats that either there is air getting into the pipe, or, if you're using bottled gas, the bottle may be running out.

Answer 7

Yes, it is normal. The blue flame is the hottest part of the flame.

Answer 8

No, that's a sign that you're running outta gas, flame must be blue.

Answer 9

Yes.. they have orange.. green(light), blue... very pretty colors
