For six years our semi-finished basement has basically been used as storage but I am finally ready to reclaim it as living space. It has a fireplace with an old smoke dragon installed. I've never lit a fire in it and don't intend to. I am sure that the stove is not installed to code. I would like to either put a gas or pellet insert in there. I burn wood upstairs but I would be a newbie to gas or pellet. I guess I have a pretty basic question about gas inserts... how does one run the gas line to an insert without it being totally exposed? It seems sloppy to just run a line over the surface of the wall. But perhaps these lines are smaller than I imagine? Secondly, if a gas insert does not have AC power, how does it spark to ignite?
