We bought the trailer and it was set up for nat. gas we are using propane. The orfice that came in the little bag is size 093, the door panel says to use 042 for propane. But also says the the propane orfice is in the bag. Which orfice should I use? and where to get one? thanks in advance.

Hi Nathan,

The .093 is the correct LP orifice . You'll also have to convert the gas valve by inverting the conversion stem if it is still set for NG.


Then have gas pressure changed to LP pressure and have a Tech adjust burner flame if needed and run a few cycles to be sure it is operating properly.



Take care and best wishes,
Robert
