    Are there options for larger vent free fireboxes? I am a builder and I need a larger vent free box and a vent less see through fireplace.
    1 Answer
    We offer single-sided vent-free fireboxes as large as 50" wide and 30" high for the viewing area (for traditional-style configurations with a log set), and for see-thru we have 36" models. If you are interested in a contemporary, linear style, we offer single-sided as large as 72" wide and see-thru as large as 48" wide.

    Hello! My husband and I were all set to purchase the Empire Tahoe Luxury Direct Vent Propane RF fireplace when we were informed by our builder that it would be to our economic advantage to purchase a ventless fireplace. Does this particular fireplace come in a ventless model?
    1 Answer
    While it is certainly less expensive to purchase a ventless gas fireplace, there is no equivalent model available to match the specs and appearance of the Empire Tahoe Luxury RF model. Personally, I would recommend sticking with direct vent for a few reasons; you can see a list of pros and cons in our Gas Fireplace and Stove Buying Guide. If you still want a vent-free recommendation, I would suggest the Empire Vail vent-free series; please see details below. Empire Vail Vent-Free Gas Fireplaces. These are available in 24", 26", 32" and 36" sizes.

    I need a second opinion please. I was told that I can not buy a new set of propane logs. I was told that I would have to buy a new insert with logs. Is that true? I have sent you a picture for you to see.
    1 Answer
    Unfortunately, that is correct. For a prefabricated gas unit like yours, the logs can not be switched out, as they're specifically designed to sit in your fireplace.

    Do vent free fireplaces need glass doors?
    1 Answer
    Almost all vent free fireplaces use a barrier screen only. Glass doors are usually not available, as they would impede heat transfer to the room.

    Do vent free fireplace inserts have a carbon monoxide sensor built into them?
    1 Answer
    While an oxygen depletion sensor is part of their standard construction, the units do not have a carbon monoxide system of any kind. It is recommended to install and maintain at least a couple of carbon monoxide detectors in any home that uses gas appliances.

    What is required to use "wellhead" natural gas in a vent free fireplace insert?
    1 Answer
    There is technically nothing separate that is required to operate an appliance on wellhead gas, however every manufacturer that I know of advises against it. Lack of odorants, possible impurities, and variation in BTU content are all concerns. To ensure safe operation, it is best to use only city supplied or treated and stabilized gas.

    Are there elevation restrictions? Can vent free be operated as a primary heat source?
    1 Answer
    Vent free appliances have an elevation restriction of 4,500 feet. Due to the lack of oxygen, they suffer from frequent pilot outages at any higher elevation. These units must also only be used as a supplemental heat source. Because of oxygen depletion, the unit will eventually shut down if used as a primary heat source. I highly recommend the use of a direct vent appliance as a primary heat source and at higher elevations.

    What makes a vent free fireplace "vent free"? Does it need a sensor? Does it need an automatic shut off valve?
    1 Answer
    Vent free fireplaces are completely self contained. By using a lower output burner system, they are able to be used with no exhaust vent. These units will also have an oxygen depletion sensor that will close the gas valve, should oxygen levels in the room reach unsafe levels. These units make excellent supplemental heat sources when installed in large areas with plenty of circulation.

    What is a millivolt control? Does the pilot light stay on all the time with a natural gas fireplace? Can you manually turn your fireplace off and on? Do you have to have a remote control or a thermostat?
    1 Answer
    A millivolt system has a small flame that generates power for the unit's gas valve to operate. As a result, they do not require outside power to operate and can be used in the event of a power outage. The only thing that would be rendered inoperable would be the blower, if applicable. Because of the amount of power the fan needs to operate, it cannot be used during a power outage. With a millivolt system, yes, the pilot will stay lit all the time with natural gas (or propane). You can indeed manually turn it off and on with the control knob. You can even turn it all the way off (extinguishing the pilot) if you wish, but you will have to re-light the pilot every time you want to operate the fireplace. Otherwise, it will go from fully operational back down to just the pilot light. The knob will have three options - "OFF", "PILOT", and "ON", indicating these three options. On almost all of our millivolt units, you can indeed purchase an optional hand-held remote control or a wall-mount thermostat. We also have hand-held remotes that feature thermostatic control.
