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.

airheatman :

The #56 orifice is an LP orifice

airheatman :

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?

Customer:

On the back plate of the valve there is a raised lettering G.L.P

airheatman :

THis sounds definitley to be LP

airheatman :

Looking up to see if I have any thing on it

Customer:

thanks I would like to make sure before applying pressure to it.

airheatman :

Nothing specific here, but with the GLP on valve and having LP orifice, I am confident it is LP

airheatman :

It would have never operated properly on natural gas with the LP orifice
