First of all, let's call it what it really is. The industry likes the term "vent-free" when talking about gas fireplaces that keep all the exhaust gases in your home. I prefer the term "ventless" or, even better, "unvented." Some people suggest "room-vented" or "lung-vented."

Not a huge deal, but the ventless gas industry wants you to feel that you're being liberated of a burden by not having an exhaust vent. I think it's important for people to know that they're actually missing something important when they go with a ventless gas appliance.
