I have a Heat & Glow Escape 135. When we try to turn on the unit the pilot light comes on for a few seconds and then turns off. The unit will not produce a gas fire. The unit is now 2 years old. The installer will not come out to work on the unit. We had the same problem when the unit was only a few months new. He would come out and fix the unit. It would run a few weeks then would stop working.Has anyone else had this problem? Looks like we will have to replace this "lemon" Heat & Glow. What brand of gas insert could anyone recommend.
