Lennox conversion kit

[Hgye]

I have a Lennox LF24-50A-4 S/N:  6398M11652 unit heater.  It is natural gas and I need a propane conversion kit.  I googled it, but cannot seem to find one for this model.  Any Lennox dealers out there that could help me?  Thanks!

Try to find a conversion kit part #20L05.

The parts break down is confusing.  They list the following,

LP Gas Valve - #10K54

LP Burner Orifice - #56L56

LP Burner Orifice #57 - #17J71

I'm not sure why they have 2 different orifice part #'s.

Thanks,
When I google that, is says "LF24 NG to LP Conversion Kit for Lennox LF24-30, -45, -60, -75 Unit Heaters".  It doesn't say it is for a 50k btu.

Lennox should be able to confirm.  Maybe you can get the 75 kit and not use one orifice.
