Burns orange? Flame is orange not blue?

Orange or yellow gas flame indicates air is not being mixed with the gas before burning.

The pilot burner has air holes to allow air to mix with the gas for efficient blue flame burning.

The air holes are probably blocked if the flame is approximately the usual length or longer. If it is significantly shorter it indicates the gas pressure to the jet is reduced.

The color of the flame can be affected by a few different things. here are three of them: 1. If there is a food substance contacting the burner where the flame comes out, this will give the flame an orange tint. 2. If the propane is being burned at a very high rate, the flame can become invisible in daylight-like conditions. 3. If the propane is being burned at a very low rate it can also have an orange tint. Hope this is clarifying.

You need to get a Plumber or Appliance Tech to come out immediately and check the fuel to air ratio. You are not burning your fuel at the proper mixture. A blue flame is good, yellow-orange is bad.

Normally this is because the burner area is dirty or the pressure regulator may be set too high/low. The black marks are a sure sign that your ratio is too rich and it's just going to build up more soot and become unhealthy and dangerous.

Don't wait...

You must get more air to water heater, and check venting .... immediate CO poison danger.
Call qualified plumber immediately.... because deadly carbon monoxide is not being vented properly.

it should be blue , too much air or burner needs cleaning , how long since it was
serviced ? t

The difference between an orange flame and blue flame is the amount of air in the combustion process. SO if the flame is orange it is being starved of oxygen. The gas burns dirty and soot is generated.

Sometimes with an older heater the exhaust venturie becomes plugged and carbon monoxide is released into your home- in this case your heater would make a woof or poping sound when starting up or shutting off. This is a dangerous unsafe situation and professional help is needed.

What you can do is try to make adjustment yourself, if your confident the other situation does not exist. Your water heater should have a little deflector shield on the gas line between valve and burner (typically immediatly after the orfice). Sometimes these will have to be slide front or backwards or twisted. The adjustment of deflector shield must be opened more to make the blue hotter flame to mak eyour heater operate at peak efficiency.

Good Luck

blue with just a small amount of orange flame flicker ervey now and then,if its orange more than blue your gas orfice is dirty or you need to open up the air shutter so you get more air to burn gas more completely

needs blowing out remove pilot tube from pilot remove injector and clean it out then replace it all test joint with soapy water to check for leaks

here is a link to a page that shows what the colors of the flame should look like and what causes the orange instead of the blue flame. http://www.appliance411.com/faq/gas_range_flames.shtml
I would begin by checking to be sure you do not have a spider or a cob web in the burner partially blocking the gas or the air intake.

its an air shutter issue
