direct vent vs. vent free gas fireplace
I'm planning to install a gas fireplace. Fortunately the location has direct
access to an unused flue on my chimney. What are the pros & cons of direct vented vs. vent free, I haven't been able to find much on the web beyond the fact that vent free will add moisture. |

My vent free also produces an odor - not so much as you notice when you're using it, but when you go outside and come back in it will be apparent. Not a gas smell, but a combustion smell. Also, after using for several hours, the digital CO2 detector will show an increase but never to the point of alarming. So IMHO, they're good for taking the chill off or for mood stimulation, but not for long term use. Red |

Which it will heat better. What do you mean specifically by don't assume the
vent isn't suitable? It's a clay tile lined chimney inside concrete block veneered with brick. "Joseph Meehan" wrote in message ... It will also heat better, but as noted it may have an odor. Don't assume that the available vent is suitable for the fireplace. Have it checked by someone who really knows first. "Jeff Dieterle" wrote in message ... I'm planning to install a gas fireplace.

Unless they've changed things, they are not legal in NY. Could be the same for other states, too. I don't know. |

What are the pros & cons of direct vented vs. vent free, I haven't been able to find much on the web beyond the fact that vent free will add moisture. I've been using a vent free inside an unused fireplace for about 7 years. Its great. We live in a split foyer (walk in and go up or down) and our basement/family room is quite chilly in the winter. A vented unit does little more than look pretty since 90% of the heat goes up the chimney. Our flue is closed, the doors are open, and all of the heat goes into the room. Keeping it on a low trickle is enough to keep the room nice and toasty. I don't have any moisture or CO issues (we have a detector in the nearby hallway.) The flame on vented units tend to look more realistic. Our looks more like a stove on high with fake logs around it (lots of blue). But again, I'm more interested in the heat than the looks. --Jeff |

My thoughts are that anything that is burning needs to be vented. Check out your chimney to make sure it is in good condition. My gas fireplace is side-vented to the outside--unfortunately, I have no chimney. Currently, I have the fireplace stuffed with insulation (I havn't turned it on in over 8 years) because it creates a cold draft. |

"Phisherman" wrote in message My thoughts are that anything that is burning needs to be vented. Correct, but the question is how much venting. Many of the new propane heaters are 99+% efficient so there is not much fume, however, they do consume oxygen. Since the airtightness of houses varies considerably, that is not a big deal in most cases. Air going out a chimney = the same amount of air infiltrating someplace Millions of homes have gas ranges and ovens with no vents and no problems.. |

Does anyone know if they are acceptable for use in Alberta, Canada (Calgary specifically)? |
