sure you have it setup right no if it doesnt come out as gas you messed it up by drilling into it

DONT!!! Drilling out the holes can cause backflash (letting the fire into the pipe) what you need is a higher gas presure. to get that you need to change the regulator. ask at your home improvement store, they can usualy help.

I pressume it is LPG. be very careful if you play around with it. The size of the injectors is carefully calculated. I am quite sure it could be done but contact the manufacturer and they will tell you the correct way. The fact is most shops that sell these are sales people. Most do not have the technical knowledge to advise. LPG is real scary so make sure you get the advice from the right people.

I am assuming you have a propane grill, not natural, hooked to your pipe line. Before I changed the orifices, I would have the regulator checked to see that it is set properly, 11" of water column, which is a tad less than 1/2 psi. Lack of pressure will cause this. If the regulator is correct you can open the orifices up a bit but you need a set of orifice drills to do so. Using standard drill sets you are likely to over drill it and then you will never get the air mixture right. One thing to check is to see if the orifice is adjustable. Remove the burner and take the orifice off of the valve. It is brass and should screw off to the right as you are looking down at it. When you take it off, is there a "coned needle in the valve? It to is likely to be brass, same as the orifice. If so, it is an adjustable orifice and can be opened up. When you put it back together screw it all the way down, then back it off about a half turn. Light the burner and then back it off a little more. You should see the flame increase. Don't go to high that the air can't be adjusted properly. Gas and air should be mixed so that you have blue flame, possibly a minimal bit of yellow or orange on the tip of the flame. Hope this helps
