Frequently Asked Questions

The following are some of the most popular questions we are asked about the ENERVEX Chimney Fans. If your question isn’t answered here, call us at 800-255-2923.

Even though the fans offer a very compact and low profile, some customers wish to hide it from the view below. The fan may be recessed or hidden, for example, with chimney pots, copper caps and cupolas from companies like European Copper and ChimneyKing, as long as the fan is allowed to vent properly. You can read and see pictures from such installations here. Call our customer support group about your specific application.
No. The temperature inside the flue can become extreme and cause the wire to melt, so you may not run the wire inside the flue. You may want to consult with your electrician.
No. The top of the fan has hinges that allow the chimney sweep to easily access to the flue without removing the fan.
Yes, the fan needs to run in order to cool itself. You may, however, run it at a very low speed.
No, the fan offers no more resistance to your chimney than a chimney cap would do.
No, the fan only draws about 1 to 4 Amps (the same as a light bulb), depending on the size, and runs on 110V, which is standard in most homes.
Any exhaust fan (i.e. bathroom fans, kitchen hood, clothes dryer, etc.) will pull air out of the house. However, proper use of the fan speed control assures the chimney fan simply simulates the natural draft required for the fireplace to operate. Thus, the chimney fan will not exhaust more air than a well-functioning fireplace would have done.
The ENERVEX Chimney Fans are covered by extensive warranties: A 2-year factory warranty and a 10-year corrosion perforation warranty.
You are likely to experience the same problems you had before the chimney fan was installed. The fan offers no more resistance than a chimney cap. Since other fans in your house – that may have aggravated your fireplace problem – are not functioning either, your fireplace may work fine without the use of the fan.
ENERVEX offers a 6-Month Unconditional Money-Back Guarantee on our fans. If you are not happy with the fan, simply return it and we’ll refund your money – no questions asked.
Yes. If you run the fan continuously at a low setting, you will be able to reverse the down-draft and/or to eliminate odors from the flue. This will not affect the longevity of the fan and – since the fan uses very little power – it will use very little energy.
