1950 gas wall heater

[Holli Haddix]

I have a rental property that was built in 1950. We recently remodeled and had the old gas wall heater in the bathroom disconnected.  It worked but we did not know if we would be renting to people with children where it could have been unsafe. We now have a couple with no children moving in and they asked me if I can reconnect it. Is this something that I should consider doing for them and would it be difficult to reconnect?
