Ask an Expert

    Yes, in most cases installation is a do-it-yourself job and requires little to no tools or experience. We're available by phone and email to support your installation, and we have a growing library of installation related content and videos available to you. You can find product related installation materials in our document center.
  • How quickly do orders ship and where from?
    All orders are typically processed within 24 hours (1 business day) of receiving payment. Orders are shipped from us same day if placed before our shipping cutoff time (Monday - Friday: 1PM, Saturday: No Shipping, Sunday: No Shipping), orders placed after our cutoff time are shipped the next business morning. All orders are shipped from our Racine, Wisconsin location using a priority or expedited service with USPS or UPS. Courier selection is based on shipping location and delivery times can vary based on courier, service interuptions and location.
  • Do you ship to Canada?
    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. For orders that can be shipped through FedEx, our preferred international courier, all duties and applicable taxes have already been paid!
  • 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.
