As others sate, LPG is higher pressure, higher energy, and needs a different fuel/air mix than Natural Gas. The regulator keeps it at the right pressure so you should be 'safe' at that point, but where it gets complicated is the fuel/air mix that is achieved using a venturi. That is a finely tuned system designed for a given input pressure and density to mix the right amount of fuel with the right amount of air -- and the whole thing is regulated to the hole size in the burner -- Those holes act as a fire-dam keeping the flames outside of the burner. Wrong hole = burnt up and/or blow'd up burner.


Long story short: Get the conversion. its cheaper, safer, and gooder.

I always like things that end up being gooder.

I absolutely KNEW someone would point it out. After I carefully decided to use "blow'd" I figured "gooder" wasn't far away.

You could try it and see (make sure the LPG is regulated), but it won't burn right without conversion.

I don't know if it would work but it would be dangerous. Natural gas runs at a lower pressure than lpg, so the holes in the burners are larger. The pressure regulators would also have to be different. Sounds like a recipe for disaster.
High pressure lpg roaring out of the too large burner holes.
