When adjusting the flame on the [ModelC] Thermowell burner, should both the upper [with screw mount] and lower slots have open gaps ? I'm having a difficult time getting the flame, when in full open gas position to be low enough. My burner wants to make very very large flames, a good solid inch and a half. Getting it down to an eight or even a quarter of an inch seems impossible...upon initial ignition, there is yellow which rapidly disppears to an all blue flame. With full gas, the Twell goes over 650 degrees............

Hello, I really had a hard time understanding what you are doing. My head must be extra dense today. Any way, I think I understand that you are trying to adjust the burner. It seems that your are messing with the Air Shutter on the input end of the burner.
With the Gas Handle full on, you need to first tignten down the Gas Orifice to get close to the correct flame height (3/8"). Then go to the Air Shutter to get the correct Blue Flame with no yellow.
Remember, The Gas Orifice controls the amount of gas entering the burner and the height of the flame. The Air Shutter controls the amount of air needed for combustion to make the Flame pretty and Blue.

Thank You Sam ! I thought the air shutter was the only adjustment I needed to make....iIn a bit, I'll go back and adjust the gas orfice. Here's the question: how to I get to the orfice ? the manual says to remove the rear burner top burner grate and drip ring....the manual is referring to the left rear burner ? If "yes", I don't see the connection to the Thermowell....I need some guidance here, thanks !

HI, You will be going in through the Service Door to get to the Thermowell Gas Orifice. You'll need an open end wrench to turn the Hex Orifice cap. I can't remember the size, could be 1/2, 9/16 or 5/8". A small Cresent Wrench will work. It is almost a two person job, one to watch the flame from above and another to turn the Orifice.

Sam, Thank You very much. Now I can see the orfice cap and understand what I need to do...I'll just wait for that secondpair of eyes to come home and we'll do the adjustments. Thanks again.

Hi Ha!
I have the yellow-flame-rapidly-deminishing-to-blue problem with my front right burner. I have tried adjusting it and adjusting it some more and cannot seem to get rid of this slight problem. I've also asked about this a couple of times on the board and not gotten any response, so let me know what works for you.

Opal has a similar problem too with one of the front burners. I am hoping that ater she gets her spa treatment, the flame will burn true blue and steady.

Hey Mark,
Gas burners are designed to light in a certain amount of time with a pot or pan on them. Put a pan with a little water in it on the burner to test for initial lighting. Remove the pan to make the proper burner flame adjustments. Also,The holes that are slow to light may have porcelain in them making them smaller than the others. If the holes are open enough, try opening the air shutter a little to make a softer flame. Regards, Sam
