Manual Draft and Damper System (EcoDamper - Solid Fuel)

An economical, sustainable and quiet draft solution for wood-fired fireplaces that saves energy and maintains safe and proper draft while protecting against dangerous chimney downdraft and fireplace spillage.

The environmentally friendly ENERVEX EcoDamper System is the first combined draft and damper system for use with wood-fired fireplaces, stoves etc.

The EcoDamper System quietly manages a perfect draft and prevents heat from escaping through the chimney when the fireplace is not in use. It eliminates the need for glass doors, opening up many new design options while allowing for a larger view area of the fire and a more natural look.

The system consists of the RSHT Chimney Fan, the Manual Fireplace Damper (MFD-S) and the EFC 211 Control.


  • Can be integrated into virtually any solid fuel fired fireplace or stove design design
  • Perfect draft saves fuel, eliminates spillage & carbon emissions
  • Protects against downdrafts and spillage
  • Chimney can be closed when fireplace is not in use, saving energy
  • No need for glass doors


  • Provides ambiance
  • Ensure proper draft & safe operating conditions at all times
  • Save fuel and energy
  • Get design freedom for virtually any chimney application
  • Discreet termination 

How it works:

The Eco Damper connects a draft and safety controller, the EFC211 to an RSHT Chimney Fan, the MFD-S Manual Fireplace Damper.

EFC211 Solid Fuel Fan Controller

The EFC 211 is a draft controller that is used with wood-fired appliances such as fireplaces, stoves and pizza ovens.

It consists of a control box and a speed control unit. The control box is typically installed on the outside of the chimney or inside an attic, while the speed control unit is installed in the room where the heating appliance is located. When used with a solid-fuel fired appliance a smoke detector and an audible alarm shall be installed in accordance with NFPA 72, National Fire Alarm Code.

The control constantly monitors the chimney fan operation. It measures the motor's current draw to dertermine if there's adequate draft to the chimney. It is used with RSHT and GSV fans and is for indoor installation only. Typical uses are:

  1. controlling the speed of a chimney fan used with a wood-fired fireplace or stove; or
  2. controlling the speed of a chimney fan used with a wood-fired pizza-oven in a restaurant kitchen.


  • Safety control for monitoring of solid fuel applications.
  • Use with RS-HT Chimney Fans and GSV Grease fans.
  • Easy-to-use control display
  • Light showing proper operation
  • Warning light
  • Complies with Building Codes


RSHT 009 Chimney Fan

Tired of smoke getting into your eyes? The RSHT is the cure. It will literally suck the smoke out from the chimney flue  This high-temperature exhaust fan is typically used in venting solid-fuel fireplaces, BBQs, pizza ovens and stoves.

Installation is clean and easy - and the fan's compact design is barely visible from the ground level. The fan can be recessed or hidden behind the chimney top enclosure.


  • Quiet Operation
  • Variable-speed motor
  • Use with solid-fuel fired appliances
  • Comes in 4 sizes
  • Complete fan and control package available from a single manufacturer
  • Low operating costs
  • 6-months Performance Guarantee
    MFD-S Manual Fireplace Damper

    The MFD-S Manual Fireplace Damper for solid fuel prevents excess heat from escaping through the chimney when the fireplace is not in use, and prevents backdraft down the chimney. It is designed for chimney top installations.

    The MFD-S is a manual operated and gravity activated fireplace damper for round chimneys. Although it is designed to support and function with an ENERVEX chimney fan, it works equally well without it. It can be used as a replacement for worn-out, zero clearance fireplace dampers.

    The damper is operated with a pull chain and handle (included) mounted in the fireplace. 

    The MFD-S is designed for chimney top installations and is rated for temperatures up to 1400°F (760°C).


    • Saves energy
    • Easily operated via a pull chain
    • No power required
    • Fits most round standard chimneys

    • Researched and ordered my fireplace from US FIreplace Store. Pricing was a fair value however, the customer service was EXCELLENT! I had an issue with the direct vent venting. I called US Fireplace and the correct items were sent out the next day AND Janessa stayed on top of my return authorization and sent me the permissions and documents I needed to return the incorrect item and no cost to me, including return shipping. Overall, I am a very satisfied customer and my fireplace looks and operates flawlessly. I am glad that I selected US FIreplace to source my direct vent fireplace. Thank you for the great service.

    • I had placed an order, through Lowe's Home Improvement, for an Electric Firebox: Revillusion RBF42. Ordered 1st part of January. Was told I would have it in 3 weeks. When checking to see is it came in, was told it was delayed to 3/15. Was then told is was delayed until 4/25. Waited until 4/27 to check on it. Was then told it was now delayed until August. This firebox was going in a new Sun Room addition. I could not get my final inspection until the Firebox was installed. I went on line and googled for this same product. US Fireplace Store web site was given to me. This was on a Saturday. I call and reached a very nice man. Explain what I was look for. He checked and told me they had 30 of them in stock. I almost fell out of my chair. I clarified with him the product I was wanting. I ask how soon could I get it. He told me it would ship today. Again, was amazed. It arrived on the following Monday. What a pleasure and a relief working with US Fireplace Store and their employees. Exceed my expectations.

    • Great prices, quick delivery and fast hassle free services on the issue I encountered. I had purchased an electric fireplace unit that would not fit into the existing fireplace space. With one email I was able to get the wrong fireplace refunded and picked up at my home at no extra cost and the new one I purchased and delivered free of charge. Great company.
