Adding a blower to your fireplace improves its efficiency because the blower circulates the hot air farther and faster than simple diffusion. Thus you are able to heat a larger area using less fuel, making the operating of the fireplace more economical. This blower made by Napoleon is built especially for zero clearance fireplaces, is thermostatically controlled and uses a variable speed feature to adjust for temperature. This item is made with all the quality you expect from Napoleon products.


  • Blower for zero clearance fireplaces
  • Precise temperature control
  • Variable speeds

Napoleon Zero Clearance Economy Blower with Variable Speed and Thermostatic Control
By Bill from Peterborough, ON on November 3, 2013
Will this blower fit a Napoleon model GD27-N?
By Tyler M. - NFI Certified Specialist on November 4, 2013

No; however, per the manufacturer, your GD27 can utilize the GZ550-1KT Napoleon Blower assembly.

I just installed the Napoleon outdoor GSS36 and would like to add a blower. Would this unit work?
By Tyler M. - Fireplace Specialist on November 22, 2011

Being an outdoor fireplace, the GSS36 has no option for a blower.

Will this blower fit my Napoleon gas insert model G13600? Is it a complete kit?
By Collin C. - NFI Master Hearth Professional on September 4, 2012

The Napoleon GI3600 gas insert comes directly from the manufacturer with a built in GZ552 blower system. This is a slightly smaller, wider version of the item in question.

Generally, replacement parts can be ordered to replace any defective items in your insert. However, because Napoleon is a Canadian manufacturer and has licensing agreements in place, we are unable to ship directly into Canada. You would need to purchase a replacement GZ552 blower from a Canadian retailer. We could also ship to a U.S. address for you to take possession of the blower.

I'm interested in a fan for a Napolean HD81? Would you please let me know if this one (or a different one) is applicable.
By Kevin E. - Fireplace Specialist on December 12, 2011

The B440-KT is not the correct blower for the HD81. However, the NZ64 is. You may find this blower here:

Napoleon NZ64 Fireplace Circulating Blower Kit

By David from Chicago on October 19, 2011
My question is whether the plug has 2 or 3 prongs? The fireplace I have has the connection there and is only for 2 prongs, but most of the pictures are for 3.
By Kevin E. on October 19, 2011

These blowers (and all blowers from Napoleon for that matter) have just two leads coming from their motor. One is designated for the thermodisc switch and the other is intended for a variable speed switch. Leads from these switches would then run to a junction box on your appliance. Upon installation, you would simply hardwire power to that pre-installed junction box on your appliance. There is no pre-attached plug for these blowers to simply be plugged into a wall outlet.

I am planning to install a BGD34 natural gas fireplace in a 10 x 20 sun porch for use in Toronto from April to November only. I'm thinking for some nights this would suffice to take the chill off the room. Should I add the optional blower or will the fireplace provide adequate heat without it?
By Collin C. - NFI Master Hearth Professional on November 15, 2012

Assuming that the sun porch has fairly standard height ceilings (8-9 feet), you should not have any problems heating the space by use of only the fireplace. The unit has the capacity to heat an area roughly twice the size of the porch, and while the blower would help to circulate heat a bit more rapidly, the difference would be only barely noticeable.

I need to replace my Kingsman Blower, model #ZCV6324n. Can I use this blower?
By Tyler M. - NFI Certified Specialist on March 26, 2013

No, this blower is only suitable for use within select Napoleon gas fireplaces. Unfortunately, we do not offer a blower for your model.

By ED Rennar from South Jersey on November 5, 2011
Can I just put this unit blower against the bottom outside part of my fireplace like you would a portable unit?
By Kevin E. - Fireplace Specialist on November 7, 2011

This blower is designed to be installed into the confined space of one of our Napoleon appliances. It is not intended to be used as a universal blower.

By scott from Snoqualmie, WA on December 1, 2012
Which blower kit do you recommend for a BDG/BCDV36?
By Collin C. - NFI Master Hearth Professional on December 3, 2012

Per the specifications for these units, the correct blower is listed as the Napoleon Blower Kit with Variable Speed and Thermostatic Control. This blower should offer proper fit and air output for this model of fireplace.

By Peirce from MA on September 27, 2013
What is the difference between thermostatic control and temperature control?
By Collin C. - NFI Master Hearth Professional on September 27, 2013

Thermostatic and temperature control are interchangeable terms, in regards to blowers at least. Both descriptions indicate that the blower will have a thermal switch that will control its on and off temperature settings.

How do I remove the blower fan from the Napoleon GI3600?
By Tyler M. - Fireplace Specialist on January 17, 2013

Please see the top right of page 10 of this owner's manual for step-by-step instructions on how to remove the blower.

By Nick from Longmont, CO on November 17, 2013
What are the dimensions and CFM's?
By Tyler M. - NFI Certified Specialist on November 18, 2013

This blower has a rating of 80 CFM. The manufacturer does not provide dimensions for this blower, as it is only tested and listed for use within select Napoleon gas fireplaces.

By Wes from Canada on October 6, 2013
I have a Napoleon direct vent fireplace in my basement. Is there a fan that I can install outside to help move the hot air? There is no air movement where the exhaust is, and the underside of my deck gets hot. I am looking for something to move the air.
By Collin C. - NFI Master Hearth Professional on October 7, 2013

Napoleon does manufacture a draft fan for direct vent fireplaces with long vent runs, but this fan is intended to primarily cure drafting issues and actually forces hot air upward from the exhaust, possibly making your scenario worse.

Use of any other type of fan may cause enough turbulence that the unit could not operate properly. If the termination is far enough from the deck to be within code specifications, you may consider fabricating a heat shield to mount just below the deck. This will help to spread the heat further away from the termination and allow time for the exhaust temperatures to cool further.

By Edward from Chicago, IL on June 6, 2013
What is the difference between the NPL-B440-KT blower kit and NPL-GZ550-1KT blower kit?
By Tyler M. - NFI Certified Specialist on June 6, 2013

The B440-KT blower has a rating of 80 CFM (cubic feet per minute of circulation) and a one-year manufacturer's warranty. The GZ550-1KT blower has a rating of 100 CFM and a two-year manufacturer's warranty.
