    Direct Vent Gas Fireplace Inserts

    Are you looking to increase the efficiency of your fireplace? Direct vent gas fireplace inserts are the most popular option. Vented gas fireplace inserts burn cleanly and directly vent the exhaust out of the chimney. The Empire Innsbrook Large Direct Vent Gas Fireplace Insert with Millivolt Controls is one of our best sellers at It comes with a beautiful heat resistant front viewing window along with a 30,000 BTU Slope Glaze Flair Burner that creates flames of varying heights. This model also comes complete with realistic ceramic fiber logs as well as a built in silent blower that will help circulate the heat in your home. This particular model has both propane and natural gas options and comes complete with a 3-year warranty.

    Can you tell me about BTU's in direct-vent fireplaces?
    1 Answer
    BTU is an acronym for "British thermal unit", and it is a measurement of heat produced by burning fuel. The general rule of thumb is 35 BTUs heats one square foot; therefore 35,000 BTUs = 1,000 square feet of heating area for a 100% efficient appliance. Because direct vent appliances vary in efficiency, the heat output will vary as well. For example, if you have a direct vent appliance with a BTU input rating of 28,000 and an efficiency of 78%, you will need to divide that input rating by .78 to determine the actual BTU output. The output for this appliance is then 21,840 BTUs in total, which then leaves us with the ability to heat approximately 620 square feet.

    I have an older Superior Dr-500. The entire insert is 36" tall and 40" wide, top vent up through roof. The system has a very meager flame which cannot be increased using the air shutter. Given the age of the unit, I wonder if I should repair or replace it. What is best? I suspect the Honeywell gas valve requires replacing. The Honeywell electric pilot seems to work fine. Ideally, I want a gas insert with an electric pilot that puts out heat as well as flame.
    1 Answer
    I would normally advise that a service call may be the best route in order to extend the life of your fireplace, but this model has a Honeywell valve that is no longer available. If a local technician decided that the best course of action will be to replace the valve as it sounds as though it may indeed require replacement, the only option will be to replace the entire system anyway, so you could spare the expense of a service call and just look into replacing the entire fireplace as replacing the valve would likely not rectify the issue with low flame height. However, I will recommend paying close attention to the product literature for any replacement fireplace you are considering as hearth manufacturers are more concerned with the fullness of the flame and flame appearance than they are with flame height. Proper combustion via the proper inlet gas pressure, air shutter adjustment and vent design will result in the most realistic flame aesthetic and max Btus for any direct vent hearth system out there. Too high of a flame can be an issue as it will create a dirty burn. If the flame shows any black tipping resulting from excessive gas pressure without the proper amount of oxygen provided via the (primary) air shutter or (secondary) venting, the inner combustion chamber (glass and valve components) will develop a buildup of soot, leading to operational issues with the fireplace. Also, the exterior wall of a structure may show this sooting if the air to fuel mixture is not proper for the fireplace.

    Do we order and then hire someone from the fireplace store to install the insert? We have both an electrical outlet next to the 'key' to our gas fireplace that is tile framed with a tile hearth that we sit on from time to time. So, should we order an electric insert or a natural gas insert with blower? Which is easier to install, and who should install it?

    I currently have a brick fireplace with gas logs. I would like to convert it to an insert. Would direct vent require me to cut a hole in the brick chimney or is there a way to vent it out the top? What is used as a power supply for the blower. Would I need regular 120V run to the insert?
    1 Answer
    With direct vent inserts, the pipe will be colinear and will run up to the top of your chimney. You will indeed need 120V to power the blower.

    I am very interested in purchasing a direct vent gas insert. I was just wondering, can I purchase an insert without a blower? I have no electrical outlet in my fireplace.
    1 Answer
    Direct vent gas fireplaces will have a blower as a standard feature. This is because of the design disadvantage of an insert having most of the chassis in the fireplace and behind the surround. The blower helps to pull heat from the chassis that would otherwise accumulate in the fireplace opening behind the surround. That being said, the blower does not have to operate as part of the design. It could simply be left idle.

    I'm building a house and interested in putting in a couple of gas fireplaces. We would like the vented type but can you tell me what kind of venting is required? How big does it need to be? Does it have to be vertical?
    1 Answer
    You will not find a suitable model in the "fireplace insert" category in question because these models may only be installed into an existing masonry or prefabricated wood burning fireplace. You will need to select a Direct Vent Fireplace and no, these fireplaces do not have to be vented vertically and may be vented completely horizontally out of the rear or horizontally with a minimum rise off the top.

    What is the best/easiest direct vent fireplace insert model to replace a Superior Natural Gas Model DS-36TN in terms of easy installation?
    1 Answer
    The fireplace and venting components are no longer in production, so I would simply recommend choosing a replacement with framing dimensions equal to, or slightly less than, the current framing dimensions of 36" W x 39" H x 15" D. Unfortunately, the venting will need to be replaced as well. One of the 33" Superior Direct Vent Fireplaces would be my suggestion.

    As long as the dimensions of the chimney flues are large enough to accommodate the pair of 3 inch aluminum vent liners that are required by the inserts, you could certainly complete the retrofit for each fireplace.

    I have an unusual fireplace opening that currently contains a wood stove. The dimensions of the opening are 28" W x 33" H x 24" H. I have a 9" diameter, round ceramic line chimney pipe without a flu. I would like to covert it to a direct vent stove or insert if I can find something that fits and looks right in this opening. Would you suggest?
    1 Answer
    While a custom surround would have to be fabricated with any insert as these are unusual dimensions, the Napoleon GDIZC Direct Vent Gas Fireplace Insert would fit this opening.

    I have a fireplace in the basement of my ranch home and I would like to install an Innsbrook 25-33LN. I want to remove the brick chimney down to the roof line. Can this unit be exhausted out the side of the remaining part of the chimney? If so, what vents are available? Are they like a dryer vent?
    1 Answer
    The Innsbrook models require at least 10 feet of vertical height before they can terminate per the manufacturer. Unfortunately, there is no horizontal termination kit available for these appliances. The vents to be used with the Innsbrook are dual 3" aluminum liners which are very similar to dryer duct work, however they are heavier material.

    I'm looking for a replacement gasket kit for a Majestic G336N DV Gas Fireplace glass. Do you have anything that would work, since the original part is discontinued?
    1 Answer
    The original gasket used on this glass was actually a high temperature adhesive, which is no longer being produced. However, the adhesive can be carefully scraped away, using an razor knife, then a 3/8 rope gasket can be installed in its place. A product such as the Rutland Fiberglass Grapho-Glas Stove Gasket with Gasket Cement Kit - 7 Foot x 3/8 Inch will be a suitable replacement.

    Do you have an insert that vents out the back of the fireplace, through a wall and then vertically to the outside? I'm building my house and fireplace and want something that will vent in this fashion.
    1 Answer
    Based on your description, you will need a manufactured fireplace, rather than a fireplace inserts. As you noticed, inserts are designed to retrofit into a masonry chimney and must be vented vertically. They are simply meant to make the existing masonry fireplace more efficient. Manufactured fireplaces are fully insulated and designed to be placed within 2 x 4 or 2 x 6 wooden framing. Almost all of them can be vented horizontally through a wall and terminated horizontally on that same wall. A vertical run is only needed if the horizontal run is too long. The only downside to the manufactured fireplaces is that their BTU output tends to be comparatively less than the inserts. You will need to decide what purpose this fireplace serves before you make a purchasing decision.

    1 Answer
    It is likely that some of our smaller direct vent inserts could work for your needs, however I will need to know a bit more information about your fireplace to be certain. What is the depth of the unit from the front of the opening to the rear wall? Also, is the metal smoke shelf held in place by fasteners or is it welded in position? If the shelf can be removed, additional clearance can be gained. Please advise at your convenience.

    My fireplace is nonexistent, though I do have the mantel and an open Ben Franklin restored front. The problem is I have only one chimney (propane) and it is not near where the fireplace has to be due to windows and house design. I am restoring an 1880 Victorian home and the only wall space adequate is not near the chimney to tap into. Is there a "kit" of some sort my contractor can use to convert the open Ben Franklin to a direct vent that can open onto the porch? Or is it possible to snake a vent across the hose to tap the fireplace? I guess we will have to build a firebox and everything - we are starting from a bare wall. Do you have any suggestions for me?
    1 Answer
    Typically, conversion kits are not made to allow an appliance to be switched between fuels. It may be possible to run your vent piping into the existing chimney, but it would be ideal to have a chimney or vent system installed at the location of the appliance. What is the distance between your install location and the existing chimney? Is the existing chimney lined? Please advise at your convenience.
