They installed our fireplace and it worked ok for about 6 months. Then the problems started. It would just shut off all the time. Fergus Fireplace's solution has been to replace the control module two times, but the problems continue 3 years later. They are very hard to get a hold of, I always have to leave a message. Last time they did not call me back and I forgot to follow up since it was summer. I wish they could give me a better solution then to replace the batteries and control module.
