Direct Vent Fireplace Inserts

Direct vent fireplace inserts aren't easily the most popular type of fireplace inserts for no reason. Direct vent fireplace inserts are very efficient, they burn cleanly and vent the exhaust directly through the chimney, and they seal the combustion off from the home for added safety and better operation. Due to their popularity, direct vent fireplace inserts are offered in all kinds of styles, in every size imaginable, and at prices that can fit any homeowner's budget. Browse our gigantic selection of direct vent fireplaces, pick the model that is just right for you and your home, and get ready for years and years of great performance with minimal maintenance.

A picture of my fireplace is attached. I am looking for an Direct Vent Insert that would best fit with the surround. The measurements are 39 W X 30 H X 23 D at the bottom and 16D at the top. I'd like to keep the traditional look, have a variable speed fan, adjustable flame, realistic logs with embers, a back light, and a remote for it all.
By Tyler M. - NFI Certified Specialist on March 15, 2013

We recommend the Napoleon Large Deluxe XIR4N Direct Vent Insert with Night Light and Radiant Ironwood Log Set. This model includes the blower, hand-held modulating remote control (with thermostat and variable flame control), a night light and a great-looking log set. You can see additional options in the "Accessories" tab on the item page and the required vent kits in the "Venting Components" tab on that same page.

I have an arched see thru woodburning masonry fireplace in my basement that i would like to convert to gas. Can you tell me what my options are? Can I retrofit a direct vent see thru gas fireplace in the existing masonry? Thanks.
By eFireplaceStore on July 7, 2014

While they are not designed with this kind of application in mind, it may be possible to install a direct vent see through unit into the current fireplace, however it will require some modification.

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?
By Chris on November 19, 2013

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 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?
By Will M. on May 26, 2015

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.

By Harold from Albany, NY on November 23, 2014
My fireplace opening is 27 1/2 inches High by 32 1/2 inches wide and 20 1/2 inches deep. The back width is 27 inches. What size insert do I need?
By eFireplaceStore on November 24, 2014

An excellent choice for your application will be the Empire Innsbrook Medium Direct Vent Gas Fireplace Insert - Natural Gas - DV-33IN-33LN. This unit is capable of heating approximately 800 square feet on average.

By Chris from Taylors, SC on October 15, 2014
I have a fireplace with the following dimensions; 36" W X 28" H X 24" D. Inner width 28". What size unit should I be looking for?
By Tyler M. on October 15, 2014

By Noelle from Oneonta, NY on November 23, 2014
There is only one measurement listed for size. Is the size the height, width, or depth?
By Kevin E. on November 24, 2014

The size filter on the left hand side of this item page indicates the width measurement of our offered inserts. The height and depth will vary depending upon which unit you select.

By Melinda from Hartford, CT on September 30, 2013
I need to order a direct vent fireplace. My opening is 37" x 32" and 14" deep. What size should I order?
By Collin C. - NFI Master Hearth Professional on October 1, 2013

While you have plenty of height and width to work with, the depth is a slight issue. The largest unit that we carry that is a close fit is the Innsbrook Large Direct Vent Gas Fireplace Insert - Natural Gas - DV-35IN-33LN. The unit requires 14 1/4 inches of depth, so it will project slightly from the fireplace. Also, because of your relatively tall height, the standard surround for the unit will not cover the gap entirely. In your case, it may be best to forgo the factory surround and have a custom surround fabricated to cover the opening. I apologize that we do not have an insert that will offer an exact fit.

What's the difference between vent free and direct vent fireplace inserts?
By Tyler M. - Fireplace Specialist on November 12, 2012

There are several differences between direct vent and vent-free fireplaces, stoves and inserts. For more information, please see both our Gas Fireplace and Stove Buying Guide and our Fireplace Insert Buying Guide.

By Deb from Boston, MA on November 18, 2015
I have fireplaces in the basement and on the main floor that go through the same chimney. Am I able to place a fireplace insert into both of my units?
By eFireplaceStore on November 19, 2015

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.

By Jon H. from Tucson, AZ on January 12, 2013
I am trying to determine the correct sized gas fireplace insert. Please see attached image for dimensions.
By Collin C. - NFI Master Hearth Professional on January 14, 2013

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.

By Sanders from Chicago, Illinois on February 1, 2014
I have an existing masonry see through woodburning fireplace. I am looking for a see through gas insert. Can you provide any suggestions?
By Collin C. - NFI Master Hearth Professional on February 3, 2014

Unfortunately, the only see through gas models we carry are designed for installation into a framed wooden opening. We do not carry an insert that can be slid into a masonry opening.

By Kurt from MS on August 12, 2014
What are my choices for the following opening size: 26.75" high x 44" wide x 20" deep? The back wall is 34" wide. This is an existing bricked fire box with gas logs stuck in it. It is not vented and stinks. I would like a vented fire box with logs. I can adjust the opening height.
By eFireplaceStore on August 13, 2014

One of our most popular selections for this size is the Empire Innsbrook Large Direct Vent Gas Fireplace Insert. This model would fit your fireplace without any modification and only requires the installation of a pair of 3 inch flexible aluminum liners up the chimney.

Can you tell me about BTU's in direct-vent fireplaces?
By Tyler M. - Fireplace Specialist on November 19, 2012

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.

By Kathy from Laveen, AZ on March 5, 2013
I have a large brick fireplace that I want to convert to a direct vent with with the following specs - 38,000 - 27,000 BTU, fixed glass front, remote control (on, off, fan speed and flame size), fan 160 CFM minimum, variable flame adjuster, standing pilot. Insert will include a complete operating system installed per the manufacturer's specs, including the insert, piping and valves, items listed above, outside combustion air, and exhaust to outside. Do you have a recommendation based on these specifications?
36 back width, 26 Depth from front to back, 28 height from hearth to top of the opening, 16 from front to back at the top

By Tyler M. - NFI Certified Specialist on March 5, 2013

The insert we have that best fits all of your described needs is the Napoleon XIR4N Large Deluxe Direct Vent Insert with Night Light and Radiant Ironwood Log Set - 40,000 BTU. This insert has an electronic ignition but features an optional standing pilot mode. It includes a remote that will control the flame height, blower speed and the night lights. You can see the necessary vent kits in the "Venting Components" tab on that insert's item page.

By Mark from MA on June 12, 2016
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?
By Will M. on June 13, 2016

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.

By Tonya from Forestville, CA on December 28, 2014
We are looking into replacing our wood burning fireplace for a propane insert but are wondering what the cost difference would be to use propane (vs wood) to heat our 900 square foot upper area of our house. What are the propane usage rates for the most efficient fireplace inserts?
By Kevin E. on December 29, 2014

Of course, fuel costs will vary widely with usage habits but the usage costs of our propane inserts will average around $0.80 to operate per hour.

By Tom from MD on January 27, 2016
What is the best/easiest direct vent fireplace insert model to replace a Superior Natural Gas Model DS-36TN in terms of easy installation?
By Will M. on January 27, 2016

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.

By Douglas Aiken from Memphis, TN on October 23, 2012
What measurements of our wood-burning fireplace will I need to select a proper insert?
By Tyler M. - Fireplace Specialist on October 23, 2012

In order to choose an insert, you will need to measure the front width, rear width, depth (front to back), and height (bottom of opening to top of opening).

For more information, please see our Fireplace Insert Buying Guide.

By Bill from Dix Hills, NY on December 8, 2013
I'm looking for a direct vent gas insert for a fireplace that is 34'' wide, 26'' high, and 21'' deep. The room is 18' x 13'. Which unit would you recommend? I already have gas run to the chimney outside. I want a blower, thermostat, and remote control as well. Can you help?
By Collin C. - NFI Master Hearth Professional on December 9, 2013

A good choice for your installation is the Innsbrook Medium Direct Vent Gas Fireplace Insert - Natural Gas - DV-33IN-33LN. This unit would heat the space with capacity to spare. This unit comes with a heat activated blower as standard. A popular thermostatic remote is the SkyTech 3301 Hand-Held Millivolt Thermostatic Remote Control with LCD Display.

By Steve from Grapevine, TX on November 4, 2013
Is it possible to change a double sided fireplace into back to back direct vent fireplaces. There is a gas supply already there.
By Tyler M. - NFI Certified Specialist on November 4, 2013

While two direct vent fireplaces can indeed be installed in a back-to-back manner--as long as the appropriate clearances are met--a see-thru (two-sided) fireplace can only be used as a single unit.

By David from St. Louis, MO on January 14, 2015
My fireplace measurements are 26"H x 30"W x 12.5"D. Can you recommend something to fit this size?
By Kevin E. on January 14, 2015

As long as your rear width dimension is larger than 17 1/4", our Small Innsbrook insert would work for you. Please keep in mind that your flue would need to be large enough to house two 3" diameter flex lines for venting of this appliance.

By Michael from Reston, VA on June 27, 2013
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?
By Collin C. - NFI Master Hearth Professional on June 27, 2013

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.

By Judie on November 9, 2012
I am looking for several fireplace inserts for a country inn (200 year-old log structure) which is being restored and we are adding a real limestone chimney. We need two inserts for one stone chimney: one for a guest suite on one side and a screened porch on the other side. With this being a frontier setting, can I get a propane vented insert without trim ? I don't need a high BTU rating but would like a large firebox with a nice flame and brick background. I really don't like glass fronts. What options are available?
on November 9, 2012

We do indeed have several gas fireplaces that would work for you. Per your criteria of vented propane appliance with no glass front, our B-vent appliances come to mind. Please follow the below link to view all the B-vent appliances we have to offer. B-Vent Fireplaces The units listed as smooth face or flush face will allow for finishing material, such as limestone, to be placed right up to the fireplace opening. These all have the option to add a brick liner assembly to the inside of the fireplace. You can find this option by clicking the "Accessories" tab from any fireplace item page. These units will work perfectly well inside your inn. However, they are not designed for outdoor applications - even within a screened-in porch. Your solution here would be to select a vent-free appliance that is specifically designed for outdoor applications. Please follow the below link to view an example. Vent-Free Fireplace Please let us know if you have any additional questions.

By Carol on November 9, 2012
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?
on November 9, 2012

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.

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.
By Collin C. - NFI Master Hearth Professional on June 6, 2013

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.
