Most burners have an adjustment under the knob. Pull off the knob and use a slender flathead screwdriver. Turn burner down to low, insert screwdriver into knob shaft and rotate internal screw until flame is at "simmer" height. Can adjust each burner separately this way.

SOURCE: burner flame height adjustment

All ignitors will always arc whenever one of them does.

I haven't worked with propane systems much, but it seems you may need the propane pressure regulator adjusted.

If the problem is only with the power burner, I would ensure that particular orifice was actually changed. The hole in a propane orifice is smaller than for natural gas.

SOURCE: kenmore twin burner.. orange flames

A <i>temporary</i> orange flame from your gas stove can also occur at peak usage times. An increase in local demand can cause a decrease in pressure in the natural gas line. If all of your gas appliances are in combustion simultaneously, this may also cause a drop in pressure, especially in older houses. If the problem persists, it is likely a dirty/clogged burner or the stove needs servicing. In general, an orange flame (on a gas combustion appliance) means incomplete combustion and carbon monoxide production.

The image below will show you how to adjust the burners. If this procedure does not make a difference, you will nee to replace the regulator on your unit.

SOURCE: low flame on left front burners high flame onright front burnners

That is food/grease buildup. Clean the holes. TURN OFF GAS to stove, then just clean the holes in the burners with a soft wire brush. Then turn gas back on and immediately relight pilot lights. If that sounds scary, call your gas company, they might come out and help.

How do I adjust the flame in my gas oven

You have to be careful when adjusting the flame because you can cause carbon monoxide issues. There are two adjustments. the orifice hood and the air shutter. the orifice hood when turned will adjust the flame amount and the air shutter will adjust the burning of the gas. the hood will be on the line feeding the burner usually on them safety valve and should be a 1/2 inch nut. The air shutter is the door like opening on the burner tube itself. Your flame should be a nice blue cone without any yellow and should not blow and walk off the burner.

How to adjust flame on propane freezer

You do not adjust the flame on the freezer. It is a preset flame. The orifice is a man made ruby that is laser cut with a spiral through it. Running a fine wire through the orifice will damage the spiral cut and cause the flame to fail. Blowing compressed air through could dislodge the ruby and remove it or cause it to be at the wrong angle which will cause the flame to fail. The way to clean the orifice is by soaking it in denatured alcohol then allow it to air dry. The burner tube also has preset slots that should not be tampered with other than making sure that they are not clogged. The igniter also serves as a flame sense monitor and should be approximately 1/8" above the burner tube.

Heater is not igniting

see this causes and fix it. God bless you
f there is no heat, check the electrical service panel for a burned fuse or tripped breaker. Relight the pilot light (see below). If there is not enough heat, adjust the burner air shutter (see below); and clean the burner ports (see below).
If the pilot light does not light or does not stay lit, clean the pilot orifice carefully with a toothpick, test the thermocouple and replace it if it is faulty (see below).
If the flame flickers, adjust the pilot (see below).
If there is an exploding sound when the burner ignites, adjust the pilot to a higher setting and clean the pilot orifice and the burner ports.
If the burner takes more than a few seconds to ignite, clean the pilot orifice and adjust the pilot light.
If the burner flame is uneven, clean the burner ports. If the burner flame is very yellow, clean the burner; open vents in the furnace room to provide more air; adjust the burner air shutter.
If the furnace makes a rumbling noise when the burners are off, clean the burner and adjust the burner air shutter.
If the air is too dry, wash or replace the evaporator pad if you have a humidifier; test the humidistat; and adjust the water-level float to raise the water level.
If some rooms are too cool and others too warm, the distribution system may require balancing. Refer to the Forced-Air Distribution Fix-It Guide .

I have an indesit cooker both gas and electric and when am using gas it produces poor quality fire which causes soot onto saucepans. please help

Soot is unburned carbon in the gas and is caused by the flame being short of oxygen. The burner assembly may be dirty or your air adjustment is off. Once a burner starts to make soot, it gets progressively worse on till it is repaired. The first thing to try is a good cleaning. If that does not solve it, look for the air adjusters. They should be near where the supply gas line meets the burner orifice. open them a little at a time and watch the flame for change. More air should clean up the cabon. Also check the gas pressure regulator for proper adjustment. It could be set too high. Let me know how your doing, OK? Roger

Regarding charmglow 720-0289. can't get a hot enough flame. cleaned all burners and made sure all orficis on the burner were clear even blew out with air hose

Are the burner flames diminishing as you turn on additional burners? In other words, is the flame size correct when one burner is lit, but too small when several burners are lit? Is the flame a nice blue color or yellow? If yellow, adjust each burner's air shutter at the end over each orifice. Have you tried adjusting the pressure on your propane regulator? (If it's red, don't mess with it) If it's a silver regulator and has a center cap, you can remove the cap to adjust the screw inside, by turning it clockwise in 1/4 intervals until the desired flame size has been reached. It's also possible that your burners have corroded closed somewhat. Do you have cast iron or stainless steel burners? Cast iron burners tend to corrode shut over the years due to moisture. Stainless steel burners just tend to rust away and flake, but usually become flare ups or out of control flames. Anyway, that gives you some things to look at. Hope it helps. Douglas

When the large burner is on, it keeps trying to ignite

Check that the burner orifice nozzle (the round thing that comes off) is properly seated on the burner manifold. Mine have a tab that must interlock.

Make sure all your burner orifices are CLEAN. Scrub them with a plastic kitchen scrubber, soap and water.

The way this works is, when a burner is turned on, the sensing mechanism for the spark control reads the ionization of the flame. No flame, no ionization, keep sparking so gas buildup is minimal in the area before a flame is ignited. )Kinda like the spark thingy's underneath the shuttle, without the ionization sensor's, just before it launches.).

Burner flame adjustment

there are two considerations for burner height. 1) the gas adjustment screw on the knob and 2) the gas-air mixture to the burner. establish a flame and adjust the screw for a standing flame at the burner. adjust the gas-air ratio orifice so that the flame has no yellow tips.
