Flue Pipe Adaptors Wireless Speed Control ADC 100 for Gas Fireplaces MFD Mechanical Fireplace Damper

Mechanical draft fan for installation at the chimney termination point, vertically or for side-wall venting. Assures a negative pressure in the entire chimney or stack system.

A residential type chimney top mounted fan to be used in conjunction with wood, gas, oil and coal fired appliances. The fan can be used with fireplaces, fireplace inserts, stoves, ovens, BBQ's, water heaters, furnaces, small boilers and more.

The Exhausto RS chimney fan mounts outside, atop the chimney, where it literally sucks the smoke from the flue. It can be installed on any type chimney system, whether it is made of steel, masonry or cast material (installation on pre-fabricated chimneys requires a special adapter).

The variable speed motor assures the chimney fan will never "over-draft" the heating appliance. The speed can be adjusted to provide a perfect draft. 

The Exhausto fan housing is hinged and the top can be opened for easy service and access to stack. For use with gas, wood or solid fuel.

The RS chimney fan is designed for minimum energy consumption, using about as much energy as a regular light bulb.

Standard equipment include: fan, mounting brackets, gasket, 5 Amp fan speed control and a pre-wired weather tight junction box.

The fan also duplicates as a ventilator: Simply turn it off to rid your home of stale air, cigarette smoke, etc.

Please take a moment to view our most frequently asked questions about our fans.

What happens when you have a fire in the fireplace and a power failure occurs?
You will most likely experience the same problems you had before the chimney fan was installed.

What if the chimney has a constant down-draft and odor when not in use?
Run the chimney fan at a low speed.

Does the fan always have to be on when I have a fire in the fireplace?
Yes, the motor can only be cooled when the chimney fan is operating. You may, however, run it at a very low speed.

The fireplace spills due to negative pressure in the house. Won’t the chimney fan add to the problem?
Any exhaust fan will pull air out. 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.
*It is important to emphasize that all furnaces, water heaters and other combustion equipment be checked for proper venting before regular use of a chimney fan.

Can the fan be recessed or hidden?
Yes, the fan may be recessed or hidden, for example, with chimney pots, copper caps, or cupolas* as long as the fan is allowed to vent properly.

Does the chimney fan have to be removed every time I have my chimney cleaned?
No, the fan has hinges on which it can be tilted open for easy access of the chimney.

Does the fan require its own circuit?
No, the fan only draws about 1 to 4 amps, depending on the size, and runs on 110 volts, which is standard in most homes.

Can you run the wire inside the flue?
No. However, you may run it inside a chase. Otherwise it will have to be run on the outside of the chimney.

What kind of guarantee do I have that I will be satisfied with the fan?
Enervex offers a 6-month unconditional guarantee, 2-yr factory warranty on motor and a 10-yr corrosion perforation warranty.

Definition of Mechanical Venting

While used for decades in Europe, mechanical venting of fireplaces and stoves is relatively new in USA. Building codes, ANSI and NFPA standards hardly mention "mechanical venting". And, when mechanical venting is mentioned it is referred to as "draft inducing", which leads to "draft inducing equipment".

"Draft inducer" has become trade name for a paddlewheel fan that is inserted into the flue between the appliance outlet and the chimney termination. There is still a misconception about mechanical venting. Many professionals still don't understand the difference between draft inducers and chimney fans.

These are our definitions that should explain the major differences:

Draft Inducer: "A fan or ventilator that is installed between the appliance outlet and the chimney termination. The draft inducer creates a negative pressure on the inlet side and a positive pressure on the outlet side."

Chimney Fan: "A fan or ventilator that is installed at the chimney termination. The chimney fan creates a negative pressure in the entire chimney system". Obviously, by pressurizing the flue the draft inducer can not be used in any stack or chimney flue that is exposed to living quarters. Using an in-line draft inducer almost always creates problems with warranties provided by stack and chimney manufacturers, and if the chimney system is listed the installation of a draft inducer will definitely void the listing. Further, the draft inducer is neither made nor designed for use in a dirty environment with creosote.

On the other hand, a chimney fan can be used on any type stack or chimney flue because it does not pressurize anything.
