Hello. My name is ***** ***** I'll do my best to help. Let's get started and see what we can do.UNfortunaley it is not covertible, The T-H3J-DV-N is designed for use with natural gas ONLY. You would need the T-H3J-DV-P for LP. Attempting to convert is not recommended and will void warranties as well as liablity from manufacturer.
Customer: replied 2 years ago.
Don't care about warranty. Can it be done? Else it is worthlessness.
Expert:  airheatman replied 2 years ago.
No. The LP operates at much hotter temperature than natural gas, The heat exchanger is not designed to operate with LP.I know this is not what you were hoping, but I can only provide accurate answers, not tell you what you want to hear.

Looking at manual, it appears heat exchanger may be same, but burner manifold, gas valve, burner damper,orifices, etc are all different.There is no conversion kit available.
