Converting ex-335 grill to propane

[LMichaels]

Especially with the way a griddle works. If you’ve got a flame thrower under there, that’s got bad written all over it.

Or if the flame does not stay properly propagated you now have a buildup of gas trapped under a very heavy and very hot piece of steel! OP do yourself a favor. If you want a NG one either A, find OEM actual Weber replacement parts, or B, buy the NG version and sell your LP version.
