    Vent Free Fireplaces

    Vent-free fireplaces have several advantages over vented models. Since they don't require any bulky vent pipe or chimney, ventless appliances have much more flexibility in terms of placement and can be used in small homes a where it would be impossible to install a vented fireplace. And, if you're searching for efficiency, a vent-fee fireplace is definitely the way to go. Vented units lose a significant amount of the warm air they produce up their chimneys, but ventless fireplaces are entirely self-contained, allowing all of the heat to remain inside the home.

    We are only considering slim ventless natural gas fireplaces (less than 7" deep). We have found the Ion Series, the Napoleon, and the Empire Boulevard. Are there others that are low-depth enough?
    1 Answer
    Those are really the only ones that offer that low of a depth. Everything else is going to be a minimum of 13".

    I have a ventless fireplace installed in my home. Temperature of heat on low is 150 degrees, way too hot. I was told all ventless fireplaces put out this high temperature. Is this true?
    1 Answer
    That is a generalization that is not really accurate. Different units produce different amounts of BTU's. Vent free sets are generally rated with lower BTU outputs then most vented sets. The fact that vented unit do lose much of that heat up the chimney make it appear that vent free units put out more heat, when in fact it is just a high percent of the heat produced is transfer into the home.

    I am trying to find out if one vent free burner actually burns cleaner than another vent free gas burner in reference to particulate matter in a season. I had a problem this year with soot accumulating around the pilot light and the metal shield above it. I have cleaned it and the soot problem has gone away, I know that the burner puts out a specified amount of particulate matter in each season, and I am curious if there are extremely low particulate matter burners?
    1 Answer
    The problem you experienced was likely due to sediment or other foreign material in your gas supply and not the burner itself, considering the problem was quite noticeable around the pilot assembly. To answer your question, all ventless burners are designed to be 99% clean burning, so there would be no cleaner or more efficient model we could recommend.

    is there a clean burning burner for non vented fire place
    1 Answer
    All vent free burner systems are designed to provide complete combustion and will burn cleanly with proper installation and maintenance. If the ventless burner is to be installed in an area where there is carpeting, candles being burned, high traffic, ceiling fans in operation, fresh paint or plug in air fresheners, etc., any ventless system will produce an odor.

    I recently moved from a home where I had an outdoor wood burning fireplace with a chimney. I had mounted a TV and a sound bar above the fireplace and I did not have a mantle. Everything worked great for over 4 years. I moved to a new home and my contractor installed a gas burning vent free fireplace since the HOA wouldn't allow chimneys. He mounted the TV and soundbar above the fireplace with no mantle again. The first time I had the fireplace on, the soundbar melted and the TV was showing signs of the same had I not turned off the fireplace. Would installing a mantle fix the problem or will I have to go to a vented fireplace. Any thoughts?
    1 Answer
    While a mantel will help protect the TV and soundbar, to ensure that no issue occurs, you'll want to go with a vented set.

    What causes a vent free fireplace to smell of gas after blowing out the dust and carbon?
    1 Answer
    Because there is no venting on the unit, you are more likely to notice the smell of gas, just as with a space heater. If this is a new unit, the logs might still be in their curing process and can emit some odor. This should dissipate with use. If you smell gas when the burner is not in operation, please turn off your gas and call a licensed technician to inspect the unit.

    Is a ventless fireplace dangerous for children, toddlers, and pregnant women?
    1 Answer
    There is no literature warning against ventless fireplace units around pregnant women or children, but ventless units have been known to bother those with allergies as they will kick out everything they draw in from the room. These appliances have Oxygen Depletion Sensors as safety measures to shut down the burner if the unit senses low oxygen around the fireplace.

    I have a 20 year old Superior VFC 38 vent free fireplace. The previous owner pointed out that it gives off black soot and said this is common for vent free appliances. Is that true? It also does not have the glass doors and she claims it didn't come with them. Is that true? Are glass doors still available?
    1 Answer
    Sooting should not be occurring if everything is installed correctly. This could be due to the logs being placed incorrectly, which will cool the flame and cause sooting, or it could be over-pressurization of the gas valve. I would suggest having a technician come out and service the unit to get it properly operating. As for glass doors, unfortunately, they are not available for vent-free units since the front must remain open.

    February 11, 2017
    There is water vapor generated when you burn propane; how does your vent free fireplace handle that issue?
    1 Answer
    All ventless systems will emit water vapor as a combustion byproduct and this will only become an issue in well insulated homes that lack a high rate of air exchange with the outdoors. This problem is normally rectified, somewhat, by properly sizing the BTU input of the chosen ventless system to ensure it is not over-sized for the cubic footage of the room the system is installed in, along with any other rooms that may be open to this space, in addition to installing the optional outside air kit offered with many of the ventless fireplaces and fireboxes we advertise.

    I have just purchased a home with an insert model GCUF36B-e. The insert has faux brick on the back and sides, but not in the bottom. The house inspector said this unit should have a bottom piece. The insert has never been used. Did the unit come with a bottom piece that was never installed, or is one not needed? If one is needed, where can it be purchased?
    1 Answer
    I recommend having your inspector contact the manufacturer if this becomes an issue, but firebrick panels used with gas hearth systems are purely decorative and not required for safe operation. Like most all fireboxes, the optional panels for this model will include the two sides and back, but not the floor (hearth) as this area is normally concealed by the burner pan and any decorative media (lava rock, etc) purchased.

    Anne Meissner
    from Cleveland Heights, Ohio asked:
    December 12, 2016
    How safe are non-vented fireplaces? How are fumes dispersed throughout the room? Do they differ in the gas burning aspect?
    1 Answer
    Ventless gas hearth systems are safety tested for safe use without the need for venting, however, these systems will require annual cleanings and are not recommended for anyone with allergies or other breathing conditions such as asthma. Because these systems provide complete combustion with the only byproducts being water vapor and carbon dioxide, they will put quite a bit of moisture into the air and lessen the available oxygen in the home slightly. While they will shut down once the oxygen level around the pilot assembly reaches 19%, this is still not ideal for anyone with asthma, etc. Additionally, newer homes with very tight insulation will not have much of an air exchange with the outdoors. In these cases, the water vapor produced may result in mold. When the system is not cleaned annually, any dust, pet dander, etc. will build up in the burner pan or on the logs. With nowhere to vent, the byproducts will simply burn away into the home, along with their somewhat toxic fumes. Lastly, if a direct vent fireplace has a 30K Btu input with 70% efficiency, it may be used more frequently to achieve the same level of heat when compared with a ventless systems with the same 30K input as these system are 99% efficient.

    Is there anything I can do to minimize the propane smell when I burn my vent free fireplace? It was installed by our builder and we had no previous experience with propane, having come from a home with a wood burning fireplace. We don't use it often. We have a full tank of propane and just had it serviced. (Had I known then what I know now, I might have made a different choice.)
    1 Answer
    If gas pressure has been verified to be in range at the unit and the log set has been placed properly, I'm afraid there is nothing else that can really be done. Vent free units do emit an odor and some individuals are more sensitive to it than others. The amount of methyl mercaptan used in the propane by the supplier can also have an effect.

    Do your vent free fireplaces have oxygen depletion sensors?
    1 Answer
    By mandate, all vent free fireplace utilize an oxygen depletion system. In the event of low oxygen levels in the room, the pilot flame will begin to lift away from the pilot tube. When oxygen levels become low enough, the flame will lift so far off of the tube that it will no longer heat the thermocouple/flame sensor. This will cause the valve to lose voltage/signal and shut down, extinguishing the main burner flame.

    What are the differences between the Monessen DIS33G and the DFS32C?
    1 Answer
    Aside from the lower Btu output and the included blower, the primary difference between the DFS32C and DIS33 is that the DIS33 is a fireplace "insert," meaning that it was designed to be installed in an existing stone or brick masonry fireplace opening and corresponding chimney. While the DIS33 can also be framed with combustible framing as an option, there are subtle differences between the log sets and optional accessories as well. The DIS33 will arrive with a cottage clay liner while the DFS32 lists several options, but will not arrive with this already installed. The DFS32 will also list several options for mantels while the DIS33 will not.

    I have had open heart surgery. How would a vent free gas fireplace effect my health if I use this as my primary heating source?
    1 Answer
    Vent free appliances should not be depended on as a primary heat source and would not be recommended for anyone with any type of breathing condition or allergy. They rely on oxygen from the home for combustion and will subsequently deplete the oxygen level without providing any type of makeup air. While the ODS or oxygen depletion sensor will shut the appliance down if the oxygen level gets to around 18%, I would not recommend installing a vent free appliance due to your condition.

    I have a 36" wide electric media fireplace. I like the style and look of the media fireplace but the electric insert just doesn't put off enough heat. So, I would like to replace the electric insert with a vent-less natural gas fireplace insert. Is this possible? Will I encounter any fire hazard issues? Is this a bad idea for any reason?
    1 Answer
    While this is a common request, I'm afraid that it cannot be safely done. The media centers do not offer enough overhead clearance in order to maintain safe temperatures. Even low output gas fireplaces require a good deal of clearance above the chassis and the relatively compact media centers do not afford enough space.

    The average vented fireplace will need to produce between 16,000 to 20,000 BTUs in order to heat an area of 400 square feet. Most likely, the venting will need to be purchased and taken as well, as manufacturer specific venting can be difficult to find. I would also verify the fuel type you will have access to, as propane and propane/butane mixtures are the most prevalent in Mexico.
