First year - said the piping was not connected properly and rerouted. Second year - said there was no propane because tank was rusty and leaking. Their tank and they replaced it. Third year - said tank was empty. Repairman extremely arrogant, said he's not responsible for the piping to my house and I should have smelled a leak. They are the only ones who have ever worked on it. I have very few fires in winter because I'm away. He was rude to security because they couldn't attend to him immediatly and left "in a snit" according to the guard.Came back the next morning.
