My guess is that you haven't cranked in enough pressure. I'm assuming it is adjustable. Go back, crank in a few turns and try again. I have 3 on one and start out with 11 cranks. Then go back and tweek as needed. Also, like the post above. Shut everything down, close the propane bottle valve, bleed the gas out, open the 30psi regulator all the way. Now open the bottle valve (needs to sense back pressure), crank in 11 turns on the regulator, go to one burner and open slowly (light). Continue opening until valve is full open and you have a goood flame. Go to the second valve, open slowly, light. If the first flame drops, go to the regulator and crank in more turns all the while watching your flame. Hope thats as clear as mud.
