Customer Questions & Answers
By Matt from Sacramento, CA on December 29, 2013
I purchased a GDS60N and ordered the fan that attached to the back, but it won't come on. Can someone help me? And yes, it's plugged in.
By Collin C. - NFI Master Hearth Professional on December 30, 2013

The fan system for this unit is both variable speed and thermostatic control. With the fan speed control turned to low or a higher speed, the thermal switch that is part of the fan assembly should heat up and close within 10 minutes of operation. If the fan does not come on, check the wiring harness from the fan to the speed control and to the thermal switch. A loose or disconnected wire could be causing the issue. If all appears connected, you can test the fan by jumping past the thermal switch.

By Gene from Huntingdon Valley, PA on October 7, 2013
Does this kit fit in the Napoleon 1101 wood insert? My blower is a GZ551 and the variable speed control is a KB-36, I believe.
By Collin C. - NFI Master Hearth Professional on October 8, 2013

I have verified with the manufacturer and the GZ552 is the current replacement blower for this unit. KB-36 is the correct part number for the control.

By tony from Rochester, NY on February 7, 2013
Napoleon DG36 vs. Napoleon BDG 36. What's the difference?
By Collin C. - NFI Master Hearth Professional on February 7, 2013

The Napoleon BGD36 is the lower output model of the two. It has a BTU input rating of 18,000 BTUs for natural gas and 17,000 for LP. It uses tempered glass to seal the firebox. The unit has an efficiency rating of 64% and could heat an area of approximately 300 square feet.

The GD36 has a BTU input rating of 26,000 for both natural gas and LP. It uses a ceramic glass window for increased thermal efficiency. It has an 86% efficiency rating and can heat approximately 600 square feet.

By Aaron from Buffalo, NY on October 20, 2014
Will this fit my Napoleon BGD42N gas fireplace? Also, are there mounting instructions included?
By Tyler M. on October 21, 2014

Yes, this blower is indeed compatible with your BGD42N fireplace and installation instructions are included.

By Rob from Kirkland, WA on November 10, 2012
I purchased this product (#GZ550) from a local company for my Napoleon BGD40N and it didn't fit in the opening under the fireplace. Could they have provided me with a wrong model? I need two of these and I'm not sure if it was them or the wrong blower.

I would like to purchase this but they didn't have any answers. Could you give me dimensions of your unit?
By Collin C. - NFI Master Hearth Professional on November 12, 2012

Specifications for the BGD40N call for the use of a single GZ550-1KT or B440-KT. The GZ550-1KT is the larger of the two blowers and has a higher CFM output, but should still work for this fireplace without a problem.

The blower should be installed perpendicular to the 36 inch sides of the unit and will mount against the wall on one of the unit's short sides, below the firebox floor. Do you have any model information from the blower itself? Napoleon makes several other larger models of blower that cannot fit into some units.

By Steve from Kansas City on October 27, 2013
Will this work with a BGD42N insert?
By Kevin E. - NFI Certified Specialist on October 28, 2013

Indeed, this is the proper blower for your direct vent fireplace.

By Darlyne from Fergus Falls, MN. on January 23, 2012
Which fan can be used for Natural Gas Model BGD40-N? It has two sides exposed.
By Tyler M. - Fireplace Specialist on January 24, 2012

This blower (GZ550) is listed as compatible with the BGD40N multi-view fireplace. You may use this one or the B440, which you can see here:

Napoleon Zero Clearance Economy Blower with Variable Speed and Thermostatic Control

The GZ550 is a bit more powerful (100 CFM) and carries a two-year manufacturer's warranty, while the B440 has slightly less horsepower (80 CFM) and a one-year manufacturer's warranty.

By on October 17, 2011
Can this blower (NPL GZ550) be used with the Napoleon GD33 NR, or do I need the "zero clearance economy blower" (NPL B440)?
By Customer Service on October 17, 2011

It's totally up to you! Both the GZ550-1KT and the B440-KT are approved for the GD33NR. The economy B440-KT is not quite as powerful or as efficient as the GZ550-1KT but it will do the job just fine.

By Helen from VT on January 31, 2013
Can this unit be installed on a Napoleon GD17 that doesn't have a blower kit already installed?
By Tyler M. - Fireplace Specialist on January 31, 2013

Per the manufacturer, yes, you can indeed use this GZ550 blower kit for your GD17 model.

By Bruce from California on October 10, 2012
Which is the best quiet blower for the BGD34-1NTE?
By Tyler M. - Fireplace Specialist on October 11, 2012

The best available blower for your unit is the Napoleon GZ550 blower.

By Pavel from Baltimore, MD on March 5, 2013
Can I manually control the blower, like speed control and turn on and off from a regular switch or from fireplace remote?
By Tyler M. - NFI Certified Specialist on March 5, 2013

Yes, this blower has a rheostat knob for variable speed control. This fan is only for use within select Napoleon fireplaces, and some of those models do feature a modulating thermostatic remote control that can indeed control this blower.

By Andrew from West Bend, WI on November 2, 2011
Is this part approved for use with GD36NTR?
By Collin C. on November 2, 2011

This is indeed the proper blower assembly for use with both the BGD and GD36NTR.

By Sena St John from Lansing on December 9, 2011
I have a wood burning fireplace. Can I use this to help circulate heat? Is it electric? Would I have to have it installed? How does to plug in?
By Collin C. - NFI Master Hearth Professional on December 9, 2011

This blower does indeed work off of a 110V power outlet and comes with a standard electrical cord that would be plugged into the outlet.

This blower is made for specific models of Napoleon fireplaces and can help to circulate heat on a louver faced model. Do you happen to know the manufacturer name or model of your unit? We may be able to find a blower to fit the model that you have.

By Jim from Chicago on October 19, 2011
have a Napoleon GD 3200-P fireplace. The blower kit listed in the manual is the GZ-550KT. Iím wondering what the difference is with your GZ550-1KT and if that one will work with my fireplace.

By Kevin E. on October 19, 2011

These two part numbers you provided are for the same blower. The GZ550-1KT blower will work with your fireplace. This has been verified this with Napoleon's technical department.

By Jason from Sun Prairie, WI on March 26, 2014
What controls the speed of the fan? Does it come with a wall-mount keypad or anything?
By Collin C. - NFI Master Hearth Professional on March 26, 2014

The fan speed is controlled by a rheostat, similar to what is used in a light dimmer switch. The rheostat can be mounted in the bottom of the unit or the wire leads can be extended to allow you to mount the control within a standard single gang switch box within the wall.

By Thomas from Brimfield, Ma on September 13, 2012
I have a Napoleon NZ-26 with a great blower that blasts heat out the front vents. It's flush mounted to the wall and the rear is framed in on the landing of my garage. I would like to be able to direct some heat into the garage/workshop. Any recommendations? Maybe a second blower and venting on a seperate switch?
By Kevin E. - Fireplace Specialist on September 13, 2012

These units are capable of use with a Hot Air Distribution Kit. These kits may be used to distribute warm air from the appliance base into a separate location in the home.

By William from Everett, WA on January 5, 2014
What is the difference between this item and the Napoleon B440-KT Economy Blower Kit? I have a Napoleon BGD36NTR fireplace and would like to know which kit would work better for my setup.
By Collin C. - NFI Master Hearth Professional on January 6, 2014

Both blowers offer the same functionality, with variable speed and temperature switches, but the GZ550 features a higher CFM output of 105, while the B440 offers an 80 CFM output. As such, the GZ550 allows for greater thermal efficiency.

By john from big bear lake, CA on December 13, 2011
What is the CFM, and how much power does it have?
By Kevin E. - Fireplace Specialist on December 14, 2011

This blower features a CFM of 105.

By Steve from Superior, CO on May 9, 2013
Which direction does the air flow? Does the air enter above the fireplace and exit below the fireplace? Can the flow be reversed?
By Collin C. - NFI Master Hearth Professional on May 10, 2013

Almost every blower system is designed so that air is drawn through the bottom louvers/insets of the fireplace and circulated around the back, with the heated air exiting from the top. Because of the natural buoyancy of heated air, the blower is able to simple increase natural convection, making it more effective. The blower is not designed to be reversed.
