FBK-250 Fireplace Blower Kit for Astria, Lennox & Superior Fireplaces


FBK-250 Fireplace Blower Kit for Astria, Lennox & Superior Fireplaces


Our FBK-250 fan kit is assembled & tested in the USA and fits a number of popular Astria, Lennox and Superior gas fireplaces.

The blower is pre-wired for easy installation and features our 100% ball bearing blower assembly.  The blower and motor are quiet, powerful and incredibly efficient.  The kit includes a full range variable speed controller with on/off position that gives you complete control of the blower's speed and air flow.  The FBK-250 kit also features an automatic thermostat sensor that is magentically attached to the underside of the fireplace.  The thermostat works by measuring the surface temperature of your fireplace and will automatically turn your blower on when the fireplace has reached a set temperature.  It will turn the blower off after the fireplace has cooled down.  The kit also includes a galvanized steel mounting bracket with pre-installed noise reduction padding to prevent vibration and noise, while also ensuring that the blower is securely mounted to your fireplace.

A thermostat switch is required in installations where no designated wall switch for the blower has been added.  If your fireplace has a designated wall switch for the blower already installed, you have the option of using the FBK-100, FBK-200 or FBK-250.  The FBK-250 must be used in installations where do dedicated switch for the blower is present.

Optional Speed Control Module - An optional speed control module (#H6487) can be added, which replaces the standard variable speed controller and thermostat switch with a height adjustable control box. The speed control module not only gives you a convenient location for mounting the variable speed control dial, but it also positions the temperature sensor in the most optimal location for your fireplace. Installation location varies by fireplace model, which can be confirmed via the provided installation instructions, but you'll see a series of pre-drilled holes on the lower front lip of your fireplace where the module attaches.  The location of these holes typically determines where the module should be installed on your fireplace.  Manufactured and assembled in the USA!

The FBK-250 fan kit is a cost effective solution for improving the efficiency of your gas fireplace.  For fitment and compatibility, please see the compatibility list below for applicable fireplace brands and models.

    Of course! We love our neighbors to the north and wouldn't leave you hanging. All Canadian shipments are made using a priority international service through USPS, FedEx or UPS. All orders are shipped within 1 - 2 business days. Delivery times can vary based on location, customs clearance and international courier (Canada Post) shipping times.

  • Do you ship to Alaska & Hawaii?
    Yes, although FREE shipping does NOT apply and no 2 or 3 day expedited service is available standard unless otherwise requested for and paid by the customer. Standard shipping is ground through UPS or USPS.
  • Is there a warranty?
    Absolutely! We offer a comprehensive 1 year warranty from the date of purchase that covers the entire blower or fan kit, including all accessories and components. Please see our warranty for additional information pertaining to coverage and how to file a claim.
  • How quiet are your blowers?
    This can be a difficult question to answer given the variables associated with blower noise. While we don't carry an official sone, dB or LP rating on our blowers, the blowers on their own are what we consider very quiet. We use extremely high quality Japanese sealed ball bearings and the construction of our blowers ensures smooth operation. However, noise from air movement, firebox resonation and room environment are all variables to consider. Remember that fireplace inserts are just metal boxes, so adding a blower that produces a significant amount of air flow, can give the impression that the blower is noiser than it really is. Some fireplace manufactures insulate their fireplaces better than others, which can also impact perceived noise. The addition of a variable speed controller or rheostat is an excellent way of controlling the RPM speed and air flow of the blower, thereby allowing for an effective method of reducing noise. Customers will often find a speed setting they're comfortable with. Others will prefer having control of the blower through a convenient wall-mounted variable speed dial. We would encourage you to watch some of our video content to get a better idea for how well the blowers are expected to perform and the noise you can expect from them.
  • Can I make customizations to the blower kit?
    Yes, in many cases we can! We offer a variety of accessories, including variable speed controllers, thermostat sensors, remote controls, high temperature wiring and more. So if you need something slightly out of the box or would simply like to add an additional accessory, we can often times accommodate your request. The exception to this might be on some of our more complicated or fully integrated kits. These might include OEM kits or specialized blower kit assemblies that require a specific configuration.
  • How does a blower's thermostat and rheostat work? Can I use a light dimmer switch?
    Thermostats, or limit switches, are heat sensitive sensors and are used in fireplace blower kit applications to automatically control when the blower turns on and off. They are most often used when a dedicated wall switch for the blower hasn't been installed or isn't available. However, they can still be used in home setups if a dedicated wall switch for the blower has been installed. In this case, the wall switch is left in the "ON" position and the thermostat sensor takes over control of the blower. Thermostat sensors come in several style, which will vary based on fireplace, installation location and temperature range.
    Rheostats, or variable speed controllers, are capacitance devices that regulate voltage and are what we refer to as TRIAC controllers. Voltage regulation is used to either reduce or increase the speed of the blower. A properly rated fan controller must be used in all fan kit applications. Light dimmers should not be used! While some light dimmers use TRIAC technology, they don't contain the necessary voltage regulation circuitry requied to operate an electric motor. Standard TRIAC light dimmers will cause fluctuations in current, which can damage an otherwise healthy electric motor. Newer light switches operate under a technology called VFD or Variable Frequency Drive. VFD devices control both voltage and frequency, which helps prevent light flickering, but most are not suitable for fan control. So it's important to use a variable speed control that is rated for fan and electric motor control. Both GE and Leviton have smart switches that are capable with fans, but must be used with a ZWave compatible hub in order to control them.
  • How can I confirm this blower will fit my fireplace?

    Most fireplace manufacturers recommend the use of a specific blower kit in their fireplace. The blower or fan kit recommended by the manufacturer can typically be found in your owner's or service manual. You can also use our helpful Find Your Blower tool at the top of the page to match your fireplace's brand and model to the correct blower kit. And finally, you can also reference the Does It Fit section in the description of every blower kit we sell, which itemizes the brands and models that each blower kit or replacement blower is compatible with. If you don't see your brand or model listed, please reach out to us directy by clicking the Ask an Expert button below, and one of our expert staff will reach out to you with assistance.
