Carrier Crusader orifice from nat gas to propane

[Nayr]

I am wanting to convert a Carrier Crusader 58ssc110-jc furnace from natural gas to propane. Does anyone have a chart that will show conversion on orifice size.

Why do you need a chart just buy the appropriate conversion kit at the supply house.

I have done that. My box contains 4 different bags with 7 orfices each in them. There is a 54, 55, 56 and 1.25. Not sure if I am suppose to do the blind fold thing and randomly select and hope for the best.

There should be some paperwork in the box showing what orifices to use at what elevation etc. That or in the original installation manual for the furnace I believe it shows it might show it there too.

Sorry, I deleted my reply. I didn't realize that I was in the resi forum.
