Hello. My name is XXXXX XXXXX do my best to answer your question.Remember, you are not charged and I am not paid until you accept my answer.
The #56 orifice is an LP orifice
I think the valve was convertible, so with an LP orifice,I would think it is set up for LP.Is there no label amywhere on it to signify?
On the back plate of the valve there is a raised lettering G.L.P
THis sounds definitley to be LP
Looking up to see if I have any thing on it
thanks I would like to make sure before applying pressure to it.
Nothing specific here, but with the GLP on valve and having LP orifice, I am confident it is LP
It would have never operated properly on natural gas with the LP orifice
