Gas stove started to flame out at highest setting. Knob wouldn't lower flame or turn off. So turned off gas. What do I do next?

I am not familiar with this stove but I think you could turn on the stove and look at the flame while you turn the knob to see which way is high or low.

as in height of flame? if its too large a flame and you have switched from natural gas to propane gas you must turn the orfice spud down onto the orfice face to adjust it,just land it lightly,do not turn it down overly tight

Be sure that the gas line to the heater is ON.

Looking at the Control Knob on top of the heater, you note that he knob has 3- positions: OFF, Pilot, ON.

Turn the control knob to the Pilot position and push down on it. If it does not go all the way in and your do not feel strong pressure pushing back at you, it is not directly in the pilot position. (Reposition the knob slightly and try again). Once You're sure the knob is directly in the pilot position and the knob is depressed, continue to hold it in and press the Ignitor button next to it. You will hear a loud click. If possible, watch the pilot assembly inside the heater when you do this. That way you can see if the pilot lit the first time. If not repeat, pushing the ignitor.

If the gas line had been turned off to the heater, the pilot may not light the first couple of tries, due to air being in the gas line. If that is the case, hold the control knob in until you smell gas, let off, wait 5 minutes and repeat the lighting sequence.

Once the pilot does light, continue to hold the control knob in for 1 minute. This will allow the Thermocouple to heat up completely. Ease off the control knob and the pilot should remain lit. If it does, turn the control knob to ON and the burner will light.

Now you're ready to set the temperature or comfort level. You do this by raising or lowering the flame height. The higher the flames, the more heat it puts out. The lower the flames, the less heat it puts out. The stripe on the knob represents the flame heights - Narrow stripe, lowest setting, widest strip, highest setting. Or your specific model may simply say Low, Medium, High.

If you do not have the Owners Manual for this heater go to http://www.desatech.com/
click on Wall Heaters and enter the Model Number of your heater. You can then download and print the Owners Manual.

Hope this helped to get you up and runnig.

Hi,
Pull the knob off and behind the knob is a small screw that adjusts the flame...

You will need to find the gas valve. Open up the lower section of the fireplace and look foe a small cube of aluminum with a knob on it that says On-Off-Pilot. Turn the knob to the Off position by lining up the word with a small dot or line indicator on the body of the gas valve. Then turn the knob to the Pilot setting. You will know when you are in the correct setting because you will be able to depress the knob into the gas valve body. Hold the knob depressed and click the larger red button. It will snap so don't be startled. Continue to hold the knob in while looking between the logs for a blue flame. If you don't see one, keep snapping the red button. Once you see the flame, continue to hold the knob depressed for 30 seconds or so. Release the knob and make sure the flame stays on. If it does not, repeat nthis procedure and hold down the knob for 45 seconds. If the flame continues to go out, you need a new thermocouple. Once the flame stays lit, rotate the knob to the On setting. The main burner should start within 15 seconds.

pull of the knob
put a smill flashlight down the selector shaft
you should see a small adjustment screw
probably a tiny flat head
very small turns
start from the lowest setting if you start from the highest you could loose your low flame below the grid
always adjust fromt the lower settings

some of these units are factory set and cannot be adjusted by the consumer,,,,unless you want to install new adjustable gas valvews

mam please check the gas line is open and if the unit is idle for long time the gas line may choked so first you check the gas line.

either turn down the gas knob or turn knobs to lowest setting without going out. That is about your only options

Not sure, but sounds like you may have a gas pressure problem or the stove is set-up for the wrong type of gas.
