I would like to bring in appliances from the U.S. but I'm concerned about the gas range and gas dryer. I have talked to the people at home depot who tell me that all gas appliances can be changed to propane (LP) by changing the orifice on the appliances but is this the then o.k. to use for butane gas? I don't want to waste my money on these appliances and then find out I can't use them. We are going to be living near Corozal.
