Here you go:

You can also forget about doing any stir frying as the burner isn't hot enough. The burners are rated at approx. 5200 btu. I have recently read about new stoves with three burners that have the front one rated as a "superburner" with about 7500 btu output.

>
> Today I removed the orifice from the front burner and drilled it with a #68 bit and reinstalled it. What a fantastic difference! The flame appears almost twice as big and it certainly puts off a lot more heat. I haven't timed it yet but I suspect that a pot of water will boil about 1.5 times faster. (it should with 7500 btu versus 5200). The flame front still is blue with no jumping so it was not necessary to make any adjustments on the air openings in the burner tube going over the orifice. I would not go with any larger bit as it would probably give too hot a flame with too much propane and you'd also have to adjust the air flow by enlarging the air openings in the tube.

> I have thought about doing all three burners but the original stove installation instructions say to keep the burners 7" from any combustible surface. I don't want to increase the heat as the two rear burners are about that distance from the walls right now and I certainly don't want any fire hazard. I may, however, drill those two out with a #70 bit just to give a little more increase.
>
> If anyone wants to do this modification but doesn't have the tiny drill bits I would be willing to do it for you (at no charge) if you mail me your orifice. To get it off you just remove the screw holding the front burner down to the pan below the burner top, pull the tube off the orifice and then unscrew the orifice. Include about $1.00 in the shipment to me to pay for return postage. However, you can probably buy the little drill for that amount at a hardware or hobby store.

Here is a link to the picture of the hotter burner in operation.
