I just lit my gas fireplace for winter and I finally noticed the statement on the equipment placard - "Approved as a vented decorative gas appliance - not a source of heat" (I have only been in my home twenty plus years). Oh well, all these years we have been using it to take the chill off of our family room, where we spend about 80 percent of our time. I instructed DW that she could only enjoy the appearance of the dancing flames, and that under no circumstances could we benefit from the alleged incidental warmth.

I must say I don't get it. Of course, the dratted thing is a source of heat.....
