Re: heater puts out dirty residue ( bad )

Check with the manufacturer but in most cases, yes blue. A dirty flame is caused by either too much gas, not enough gas, too much air or not enough air. By cleaning the burners you may have inadvertently misadjusted the unit. Contact your gas company to get a technician in to inspect it.

Pilot light wont stay lit it has a blue flame with a yellow tip

This could be due to a bad thermocouple, dirty pilot assemby or a bad gas valve. Clean the pilot assembly and replace thermocouple first since it is inexpensive, and they should be replaced every few years. If this does not help a new gas valve will be needed.

My patio mushroom heater lights up ok but keeps going out by itself after about 5 to 10 minutes and then can be started again inatantainiously by starting pilot light and away you go until it goes out...

Here's a few things to check. When you light the pilot, is it a strong blue pilot flame, a weak blue flame or a lazy yellow flame? Is it heating the thermocouple enough to make it red hot after a few minutes? If the pilot is small blue or lazy yellow flame, it may be dirty and need cleaned. When the burner lights, the weak pilot flame may diminish causing the thermocouple to cool off enough to shut down the main burner. Clean the dirty pilot orifice by using a can of compressed air with attached straw. (The same canned air you use to clean computer keyboards) Blow it into the pilot assembly where the pilot flame burns out from and blow thru the air holes on the side, if applicable. You might also check the thermocouple itself to make sure the tip is not partially burn't off. It should be a smooth, rounded tip. Replace the thermocouple if cleaning the pilot orifice doesn't solve the problem. Douglas

What colour should your gas heater flame be

It should be blue. If it's got orange tips, it's burning dust, If it's got yellow flames or tips, it may need the air shutter adjusted, regulator pressure adjusted, the vent unblocked or just a real good cleaning. Douglas

On a patio heater why is the flame yelow and noisy

Your gas/air mix is not correct. Not enough air. You should be able to adjust the unit and correct this. Read the manual first to find the adjustment and procedure. When properly set the unit should have a blue flame with a white or very small yellow tip. Thanks for using FixYa and for the generous rating.

Endless summer patio heater--turn it on full and it just gives a low flame. It is blue , but no orage or yellow tips. I have already cleaned the burner and orfice.

There is probably a pressure regulator somewhere in the gas line... this will need to be adjusted to a higher pressure or it has gone bad...

My blue flame heater has yellow tipped flames?

yes - it needs to be serviced on a regular basis. It will have an accumulation of dust in or around the burner

move the collar away from the orifice for a blue flame. too little air causes incomplete combustion so you get the yellow tinging

Hi ejohn,

There is no valuable, practical adjustment for the flame on a Toyo Stove. A yellow flame can be caused by several things. How old is the stove? When was the last tune-up? A dirty sooty carboned up stove will have a yellow flame. A breach in the flue pipe will cause a yellow flame. An incorrect installation of the flue and exhaust hoses/metal exhaust elbow will cause a yellow flame. In the last scenario, the intake will be hooked to the exhaust and the exhaust will be hooked to the intake ports of the flue pipe. A malfunctioning fuel pump can also cause a yellow flame. The wrong fuel can cause a yellow flame, too. Most likely, your stove is dirty and needs a tuneup. It should have a bright blue flame if it is clean, and operating correctly. You can download a manual at REE, Anchorage through a Google search. If you want a more detailed diagoses, write back and give me more detail and I can help you further. Toyotech
