I want to know if there is a way to convert a 1983 hiel furnace to lp gas that is currently nat gas.And if I even need to do anything?I did see some parts that are $200 valve assemble?Can I just rpl cheaper and smaller parts in the vlv?Ita a old funace and would hate to put $200 buck and it not work.Any suggestions? Thanks Mike in Colorado.I will be using this for my garage.

Changing from natgas to LP requires more than just connecting the new gas supply. Provide complete model# of unit to allow data look-up.
