Fireplace Insert Blowers and Fans

Fireplace insert blowers and fans allow you to increase the efficiency of your fireplace by improving air circulation and distribution. A fireplace insert equipped with a blower or fan system can also warm an area more quickly and evenly than one without either of these accessories. The only thing you have to keep in mind when selecting a fan or blower is that some insert models already come with them. Be certain to check your owner's manual before ordering.

I have a wood-burning fireplace with an insert installed, probably when the house was built in 1969. There is a 29" by 4.5" vent above the fireplace opening that has three tubes connected to it so the heat can come out the front from the backside of the insert. There is another five inches of air space between the back of the vent and the beginning of the tubes.

On the sides of the fireplace are two more vents, 8" by 11" approx. so the heat can escape from the sides of the insert. Can I install a fan somewhere? There are no glass doors on the front. Are there battery-operated fans?
By Staff on November 9, 2012

Answer:
From your description, this sounds like an older style of insert manufactured by Majestic or a similar company. These companies used a "heat exchanger" design as you mention, as well as the additional side ducts. The side ducts on most of these units came with 110 volt fans installed.

The fans would actually push air inward to the back of the insert. The air would then circulate around the back of the insert and then out through the large top opening. Most fans used now are squirrel cage types, which are mounted in the front bottom of the insert.

I have a small wood-burning fireplace. I think that the chimney may be too short because it gets smokey in the house when the wind is heavy, even with the flue open. I am interested in a blower/fan option. Would this be a good choice in this situation?
By Collin C. - NFI Master Hearth Professional on December 12, 2012

Answer:
A blower is intended to circulate heated air into the room from the fireplace, rather than to assist in drafting issues. In your scenario, it would be necessary to extend the chimney to alleviate the pressure issue caused by the wind.

If extending the chimney is not an option, you may try using an anti-draft type of cap, which is designed to prevent against wind-induced backdrafts. Is your chimney a masonry type or a manufactured pipe?

I have a natural gas fireplace. I would like more heat to warm the room and would like to put a blower/fan in the fireplace. How do I know if this can be done?
By Collin C. - NFI Master Hearth Professional on January 24, 2014

Answer:
The manufacturer and model of the fireplace will determine whether or not a fan can be used to circulate heated air. If the unit is indeed a prefabricated model, with a metal chassis, there should be a build plate located just inside the opening, on the left or right side. Another potential location is in the bottom of the unit, behind the bottom louvers.

Hello, I am looking for a universal blower for our fireplace insert or specific to our Archibald Ind., Ltd. Marquis AGDV-38. Can you assist?
By Tyler M. - Fireplace Specialist on October 22, 2012

Answer:
Unfortunately, no. All of our blowers are model-specific and we do not carry one for this particular model. We apologize for the inconvenience.

I have a Lopi Flex 95 wood burning insert. It was made in the early 90's and it needs a blower assembly to better distribute heat in our house. Can you provide a new quiet fan? This stove has never had a blower assembly does it also need a cover (shroud) or can I have a sheetmetal friend make one up?
By Collin C. - NFI Master Hearth Professional on February 21, 2014

Answer:
While we do not have specific blower assemblies available for Lopi stoves, it appears that it uses a self contained front mount blower, similar to what is used on the Osburn brand of stoves we offer. The amount of space between the hearth and the bottom of the ash lip will need to be known, so that I may suggest an assembly that is short enough to fit. Please advise as to the distance between the two.

You may check with a Lopi dealer to see if the original shroud is still available for this model. If it is not, you will indeed have to work with your friend to have one fabricated.

I have a Gas fireplace as seen in the attached pictures. My house was built in 1994 and this Fireplace is very inefficient, as it does NOT blow or have any means to blow the hot air to the living room, we currently use to watch TV. I'm writing to validate is their is a possibility to improve this unit.
By Tyler M. - NFI Certified Specialist on February 10, 2014

Answer:
Thank you for the photos. If your existing fireplace was sold as a gas fireplace system, the entire unit will need to be replaced. We recommend a direct vent fireplace for increased efficiency. You can see our full selection here:

Direct Vent Fireplaces

If your existing fireplace was originally designed to burn wood and you then installed a vented gas log set, you could replace the existing burner and log set with a ventless unit. You can see our full selection of those here:

Ventless Gas Logs

Please let us know if you have questions about either of these options.

I have a 30 year old Craft Stove Fireplace Insert by National Steelcrafters, who are no longer in business. It came with my home and there is no manual and I cannot find one online. The fan has burned out and needs to be replaced. Do you have any advice?
By Collin C. - NFI Master Hearth Professional on January 9, 2014

Answer:
On older units that are no longer produced, the best way to proceed is to remove the fan assembly and carefully separate the fan motor from the fan cage and shroud. Using the information for the motor, you can source a new motor that has the same voltage and similar RPM, amperage, and shaft size. You can then reassemble the fan. Replacement motors can often be sourced from commercial and industrial electrical suppliers, such as Grainger or any other HVAC supplier that carriers generic electric motors.

I do not have a blower or fan on my fireplace. Will I have to replace the unit that is in my fireplace to have a blower?
By Tyler M. - Fireplace Specialist on November 8, 2012

Answer:
This will depend on the model of your current fireplace.

I have a wood burning insert that is used and missing the blower. On the solid front doors are the words "The Fire Boss". Can you tell me who the manufacturer is, or how to locate the model and serial number? It is so dirty that I am unable to see it.
By Collin C. - NFI Master Hearth Professional on September 17, 2013

Answer:
Unfortunately, this is not a model/brand that I am familiar with. There is sometimes a build tag that is affixed to either side or the back of the insert body, which will have the the manufacturer name and model number of the stove.

If you are unable to locate this information, the only other option will be to try and retrofit another blower in place of the original. If you have an idea of how large the blower housing is, I can attempt to locate a suitable replacement.

I have an FMI fireplace that is about three years old. It has never blown air very strong at all. I opened it up and there are two little fans in the bottom. Is that enough power to blow heat into my house? It only has an on/off switch, with no variable speeds. You can barely feel it blowing when you put your hand up to the output vent. I would like to see if I can replace it with something stronger. Can you help?
By Collin C. - NFI Master Hearth Professional on October 30, 2013

Answer:
The two fan system is definitely one of the weaker blowers manufactured by FMI. Most units that used this blower assembly could also use a rotary cage type blower, which has a higher CFM output. To be sure your unit can use the blower, I will need the model number of the fireplace.

I am having trouble identifying my insert and I am having problems with my blower. I have attached photos. Can you help me?
By Collin C. - NFI Master Hearth Professional on December 16, 2013

Answer:
Unfortunately, I am not able to tell what type of manufactured fireplace you have. I have not come across a system that has such a large rotary fan. Because currently produced fireplaces have gotten away from bladed fans such as this, it is likely no longer available. If the issue is with the electric motor in the fan assembly, I recommend removing the assembly and inspecting the motor for information. If you are able to locate an electric motor of the same voltage, size, and RPM, it may be able to be used as a replacement.

I currently have a blower/fan in my fireplace. How do you go about seeing if you can get it to push out more heat and blow out more?
By Collin C. - NFI Master Hearth Professional on January 16, 2013

Answer:
Unfortunately, the fan will not perform past its rated RPM or amperage, so there is not an effective was to increase output from the fan. Many models of fireplaces offer 2 or 3 fan options, with some of the fans producing more output than others. If you would like to provide the manufacturer and model number of the unit, I will be happy to look into potential fan options.
