How do we get our insert installed after we purchase it?
By Collin C. - NFI Master Hearth Professional on September 30, 2013
Answer:In order to install the insert, you will need to contract a local contractor, NFI technician, or HVAC professional to do the work. I recommend checking with a few local businesses to verify they are familiar with that type of installation first.

We have a natural gas fireplace that does not give off a lot of heat. We are thinking about getting a natural gas fireplace insert. Would that give us more heat? Right now there is a metal covering on the fireplace with two glass doors. Would we leave that on as a covering or would that be replaced with an insert?
I wanted to see what our options were for inserts. How would I measure the opening to see what inserts you have that would work with our fireplace measurements (because there is a covering on the fireplace now)? We have a chimney now were it vents to.
Do the inserts you sell have blowers on some of them? I saw you have both direct vent and ventless options - since we have a chimney, would we get a direct vent? Can homeowners install these inserts themselves?
By Collin C. - NFI Master Hearth Professional on November 19, 2012
Answer:Per your description, it sounds as if you have a true masonry fireplace with a glass door enclosure added. In order to take accurate measurements of the fireplace, you would need to measure the front and rear width of the fireplace opening, as well as the depth.
Because you have a functioning chimney, you would be able to use either a direct vent or vent free insert. Vent free units are more efficient and give more heat, however some people can be sensitive to the smell they produce. Direct vent inserts draw all of their combustion air from outdoors, as well as vent their exhaust to the outdoors.

How do you measure your fireplace?
By Will M. on February 21, 2017
Answer:You will need to measure the front width, rear width, depth, front height and rear height of the fireplace opening to be absolutely certain any insert will fit. You will need to compare your measurements to the minimum opening requirements provided for each insert.

I teach a class for a local college. I have never installed any of the items you sell so I personally am not at all familiar with the process. I am going to be covering venting in an upcoming class and hope I can ask a question or two from folks who obviously know far more than I.
I heard years ago from a friend in the field that you can not simply stick a gas-fired insert into an existing fireplace, that you must run a vent off the gas fired unit up through the chimney. And I see that you sell vent kits and chimney liners for that purpose. Could you help me out and explain the reasons for that and what the considerations are for this. Thank you so much for your time.

Answer:In regards to B vent inserts, which draw combustion air from the room, the primary reason it is a requirement to line a chimney is because of the relation between the size of the chimney and the buoyancy of the flue gases. If a chimney is over two times the size of the flue collar cross section, the flue gases will cool rapidly enough that stagnation of the gases within the flue can occur. This leads to a blockage of the gases, causing possible spillage of additional flue gas into the room. At the very least, flue gases may escape from the chimney, but they will begin to condense on the walls of the chimney before they escape, causing moisture damage to the appliance as the condensation drips onto the unit below. By using a liner sized to the flue collar on the appliance, flue gases remain hot and will escape from the chimney with more velocity, ensuring the appliance operates as it should and spillage does not occur.
Direct vent inserts are sealed to the room by a pane of tempered or ceramic glass. These systems use a pair of aluminum liners, which are usually 3 inches in diameter. One liner draws combustion air from the outdoors, while the other vents exhaust gases. The exhaust liner must run the entire length of the chimney for the same reasons as the B vent inserts, save for the fact the spillage will not occur, due to the fact that the unit is sealed. However, if exhaust gases cannot escape, the burner inside the unit will be smothered and cause the flame to extinguish. Likewise, the sources of combustion air and exhaust must remain isolated from one another from beginning to end, as to prevent any issues with mingling of the gases. I exhaust gases are allowed to leak into the incoming combustion air with sufficient quantity, the flame can once again be smothered.

We bought a 20 year old home with existing vent free logs. We very rarely use it, I am wondering if the newer logs have improved over the past 20 years?
By Will M. on December 6, 2016
Answer:It may be that the existing logs have simply not been cleaned in quite some time. If this is the case, any dust, pet dander, hair or lint, etc., that may have accumulated over the years will simply burn off into the home. However, it could be that the actual logs are composed of the lesser-cost ceramic fiber material commonly found with ventless logs. If this is the case, these logs degrade over time and will hold a smell with no good way to remedy the issue aside from replacing the logs. Unfortunately, the original logs are often no longer available as the log styles will often change, rendering the replacement logs discontinued and complete replacement as the only option. If this is the case, I would seek out the upgraded refractory ceramic material used with all of our Real Fyre branded logs and many of the higher-tier ventless log sets offered on our site. Also, any ventless log set will produce an odor when installed in a high traffic area or in a room with a ceiling fan in operation. Additionally, the smell may be the result of odorants added to the fuel supply as a safety mechanism to detect any gas leak. This only pertains to propane gas as it is heavier than air and will sink to floor level, unlike natural gas, which is lighter than air.

I have a Majestic fireplace model MBUC (new in 1997) and since the day we bought it the fans have been loud - so much so that we never use the blower. I would love to finally resolve this. There are two small fans in the bottom that are just too loud. Is there a replacement for these that may be quieter?
By Collin C. - NFI Master Hearth Professional on December 6, 2012
Answer:This was a common complaint with this particular fan kit and Majestic has since moved away from the impeller fan design and is now using a squirrel cage version. Unfortunately, the fan kit you have, known as the UFK, has long since been discontinued and does not have a direct replacement.
It is possible to retrofit a newer fan kit into this unit, but it would require cutting the sheet metal mounting brackets for the old fan assembly.

I have 24" Savannah Oak natural gas logs for an existing old fireplace in my home. I need some sort of fan (or blower) to blow the heat out into the room. I would like to use this as my main heat for my house, although the logs do not put out any heat.
By Will M. on December 19, 2016
Please note that vented gas logs installed inside a prefabricated wood burning or masonry fireplace will not produce any measurable amount of heat. Also, these systems are roughly 10% efficient as 90% of the heat produced will be lost up the chimney. Lastly, no gas hearth system with a decorative flame to resemble a wood fire should be used as a primary heat source.
With that being said, we do offer the Stoll 24 in. W x 20 in. D Grate Heater for Vented Gas Logs.

I have an existing 36" gas fireplace and I want to replace it with a 60" unit. Will an insert work or do I need an entire fireplace unit?
By eFireplaceStore on January 20, 2015
Answer:Because you desire to replace the existing system with a much larger unit, you will indeed have to remove what is there now and reframe the opening for use with the larger fireplace.
By Brett Henderson from Houston, TX on January 14, 2017
I have a traditional brick fireplace, the opening is 40" wide by 24 inches tall x 20" inches deep (deepest part). What insert would work best? I am looking for a clean contemporary look. The existing fireplace has a natural gas connection in it.
By Brennan W. on January 16, 2017
Answer:I will be happy to make a few suggestions. What is the width at the rear of the fireplace opening? And would you like a vented or vent free insert?
By Liz from Tucson, AZ on April 14, 2016
Do you need a chimney for a direct vent gas fireplace insert?
By Chris C. on April 14, 2016
Answer:A direct vent gas fireplace insert does indeed require either a masonry or wood burning factory built fireplace with a chimney in place in order to be installed. Many of the inserts we carry utilize a pair of 3" flexible aluminum liners which are to run from the insert to the top of the chimney. If no fireplace is already in place, or the chimney does not extend above the roof line, there are methods to adapt the colinear liners to a co-axial system so that the pipe may safely pass through the roof line and maintain clearances to combustibles.

I currently have a wood burning fire place and would like to replace it with a gas or other option fire place. Can you tell me what type you recommend?
By Tyler M. - NFI Certified Specialist on March 25, 2014
A direct vent gas fireplace insert is a good option to install inside your existing fireplace. These inserts provide good supplemental heat while providing a nice, realistic flame. We have both traditional styles with a log set and more contemporary models with fire glass. Please see our full selection below:
Direct Vent Fireplace Inserts
This inserts are installed inside your existing firpelace and must use co-linear (side-by-side) aluminum vent liners (3"/3" or 3"/2" diameters) all the way up to the top of your existing noncombustible chimney. Please reply with your fireplace dimensions and preferred style and we can offer some specific suggestions.

I already have a gas fireplace which vents thru a chimney to the outside. It uses a lot of gas. Do you sell anything that could make my gas fireplace more energy friendly? I have gas logs and glass fire screens. It is a double sided gas fireplace.
By Will M. on January 2, 2017
Answer:If this were not a see-through fireplace, I would suggest installing a fireplace insert for maximum efficiency. As it is see-through, my only suggestion will be to install a set of appropriately-sized see-through ventless gas logs and close the damper.

How do I measure the interior of my fireplace to get the correct size insert?
By Tyler M. - Fireplace Specialist on December 10, 2012
Answer:We need your full fireplace dimensions (front width, rear width, opening height, depth, etc.) as well as what type of insert you need (full-bodied direct vent insert, full-bodied vent-free insert, vented gas log set or ventless gas log set) and your fuel type (natural gas or propane).
Also, please let us know if your existing fireplace is a brick/masonry unit or a steel (manufactured) model. With this information, we can provide some recommendations for your application.

How safe are vent free fireplaces?
By eFireplaceStore on January 21, 2015
Answer:When installed properly and used in the correct environment, vent free fireplaces are safe to use. It is important that the correct fuel type be verified and that log placement is correct during the initial setup. Vent free appliances do best in larger rooms with low humidity levels. Installation near windows or in small spaces is not recommended.
By Mike from Great Falls, MT on July 21, 2014
We currently have a natural gas insert in our home. It is in a wall that is visible from both sides or both rooms. It is more of a decoration than a heat source, because it has no fan. Does the Fireplace Store have an insert that can be a useful heat source for this situation or could you point me in the right direction?
By Tyler M. on July 21, 2014
Answer:Yes, we have a few see-thru (two-sided) gas fireplace options, both as full-bodied zero-clearance fireplace systems and as stand-alone gas log sets. Please advise which configuration you need and we can proceed with some recommendations. In either case, we will need to know the available dimensions you will have.
By Ben from Berkeley, CA on March 10, 2015
I have a wood burning stove that is inside of a fireplace and I would like to replace it with a gas burning insert but I do not know what kind of insert that I will need. It would seem neither direct vent or ventless inserts would work for me. The opening of the fireplace is 29.5" high and 28" wide. The width at the back of the fireplace is 18.5". The depth of the fireplace is 18.5" at the bottom and 16" at the shallowest which is about halfway up. Can you advise me on what kind of gas insert I would need and what sizes/models might work best?
By Kevin E. on March 10, 2015
Given your location, I would not recommend a vent free appliance. These are prohibited from installation in California. A direct vent insert would actually work just fine for you. You would simply remove the stove and associated vent pipe. The insert would push right into your fireplace opening and the requisite direct vent pipe could be dropped down your chimney. The one difficulty in matching an insert to your fireplace is the similarity between your fireplace's height and width. Most inserts and their required flashings are designed to fit fireplaces that are much wider than they are tall. What this means for you is that our Small Innsbrook Insert
is the appropriate insert for your application but the available surrounds would be about 4" too short for your opening height. A custom backer plate would need to be used to finish out the installation.
