I have a Heat & Glow AK515728 Model # GR-40, RH-42 series fireplace. It has a gas starter,and I would like to have installed unvented gas logs. Is that possible with this model. I've contacted a few companies. One told me yes it could and gave me a quote for the job. The other asked me for more information about the fireplace. I supplied the the information about the fireplace. The reply I received was that it was not designed for unvented because it will run hotter than the fireplace was designed for. The guy said that Heat & Glow and Heatilator were the same company....and the unit could not be converted to an Unvented natural gas fireplace.
