My 30,000 BTU lpg torp heater has started burning back into the mixer tube , and I can't figger it out . I have so far tried an adjustable regulator thinking that maybe the original was malfunctioning and I've pulled a wad of steel wool thru the tube in case a little roughness might be affecting the air flow or maybe a spider web doing the same . No joy , it still burns back into the mixer tube . Any thoughts on what else might be causing this problem ?
