Yes, almost all natural gas appliances can be converted to propane, and come with the instructions to do so. In NH natural gas is only in the cities, all rural houses (that want it) use 100-500 gallon propane tanks instead. It's very common here. When I built my house new in 2018 I installed a 500 gallon tank for the heating system + cooking. (Though the house is primarily heated with a wood stove)
