Chimney Fan – Mechanical Venting



Chimney Fan

The perfect fire features a flame that’s just the right size. Not too high. Not too low. But to achieve the perfect fire, you need the perfect Chimney Fan. That’s why Isokern and Enervex, two leaders in the fireplace and venting industries, have teamed up to ensure proper chimney draft for air tight environments.

Fireplaces can be vented by gravity or by mechanical means. Gravity venting uses the difference in gravity of cold vs. warm air to create draft for fireplaces. Whereas mechanical venting uses a fan to create proper draft.

Utilizing an ENERVEX mechanical venting system is an economical and environmentally

Chimney Fan

friendly solution that quietly maintains perfect draft for fireplaces. Each mechanical venting system will recommend ECO-STEEL or ECO-STEEL+ insulated chimney to provide the quiet comfort, so you’ll never even notice it’s there.

Also available by ENERVEX is the Multi-story Fireplace Exhaust System (MFES). With this innovative technology, a single exhaust system can vent multiple gas-fired fireplaces in a single chimney. The fireplaces are monitored through an integrated electronic system allowing each unit to operate individually.

ENERVEX’s systems qualify for LEED points under the Energy & Atmosphere, Materials & Resources, Indoor Environmental Quality and Innovation & Design Process sections.




Made of high quality, recycled cast aluminum, the RS Chimney Fan keeps the perfect draft for gas appliances. The fan features a quiet, enclosed prelubricated motor. The FSC variable Fan Speed Control comes standard with the fan.


Mechanical Fireplace Damper

The low profile Mechanical Fireplace Damper (MFD) is an accessory to be used in conjunction with an ADC100 and RS Chimney Fan as part of the EcoDamper System or an ADC150 and RS Chimney Fan as part of the IntelliDraft System. This gasketed damper prevents conditioned air from escaping through the chimney when the fireplace is not in use and eliminates the need for glass doors.



The ADC100 and ADC150 Fan and Damper Controls, for gas fireplaces, feature a draft switch that shuts the appliance off when there is not enough draft, protecting your family from dangerous flue-gases. The ADC150 has the added feature that automatically maintains the perfect draft by modulating the fan speed when the pressure changes.




Use the PDS1 Proven Draft Switch to provide protection from insufficient draft. When there is an unsafe draft, the switch shuts down the gas-fired appliance or fireplace.





The RSHT Chimney Fan is a high temperature fan used to maintain the proper draft in a solid fuel chimney or stack system. It is intended for wood burning fireplaces. It boasts a 1000˚F temperature rating. The FSC variable Fan Speed Control comes standard with the fan.




The MFD-S Fireplace Damper for solid fuel prevents conditioned air from escaping through the chimney when the fireplace is not in use and prevents backdraft down the chimney. It includes an easy-open pull cable and handle that is mounted inside the fireplace.




The FCS Fan Speed Control is used in conjunction with all single-phased chimney fans. It is specially engineered to provide variable speed control of split capacitor motors.

We have owned an Isokern Fireplace in our home for over 9 years now. We like the Isokern pre-engineered firebox produces a consistent fire draw. In the past we had experienced some poor draws in our existing fireplaces and wanted a better fire experience. We also liked that the interior firebrick could be customized to give you various looks for the fireplace. We would definitely consider another Isokern Fireplace for our outside porch.

We have been working with Earthcore for many years. On the product end, the Isokern Masonry products they manufacture are second to none. The precision in which they build their components is unlike anything we have ever tried.

On the business end, we love the staff at Earthcore! From the employees I met at their factory, to the owner of the company I had the pleasure of meeting at a trade show in Nashville, TN……this company is a great organization that I look forward to growing with for many years to come.

I’ve been woking with Earthcore for years. Claudia has been very helpful making things go smoothly out in the field and in helping with choosing the right fireplace to achieve the best looks. I have had great feedback from past customers on the product and plan on continuing to use these fireplace units.
