EcoDamper Diagram




EcoDamper™ - How It Works

An elegant - and yet very simple – venting solution. The EcoDamper system is easy to install and the connection of the components is very simple. And all the components, except for a switch, stay out of sight. The illustration to the left shows the very simple set up.

The EcoDamper connects a draft and safety controller, the ADC100 and its pressure sensor, to an RS chimney fan, the MFD chimney damper and the fireplace’s gas valve.

When the user wants to turn on the fireplace – typically using a wall switch – the controller signals the mechanical chimney damper to open. When the damper is open, the controller automatically ramps up the chimney fan speed up to the pre-set speed whick closes the integrated draft protection switch

At this point, the controller allows the fireplace to fire by opening the gas valve.

When the user turns the fireplace or appliance off, the control leaves the damper open until all residual combustion products have been exhausted out of the fireplace and chimney by the chimney fan; then the control discontinues chimney fan operation and closes the damper.

If for any reason the adjustable draft set-point can’t be maintained during operation, the controller will completely shut down the fireplace or appliance operation.

Events that could cause a complete shutdown include:

  • Extreme chimney downdrafts
  • Extreme building depressurization
  • Electrical blackouts
  • Electrical or mechanical failure to any EcoDamper system component

The EcoDamper system addresses all the relevant safety and energy-efficiency concerns in one cost-effective, code-compliant system. Added to a gas fireplace as a retrofit or in a new building project, the easy-to-install EcoDamper suite provides a completely safe gas appliance system:
 
Downdraft protection. High winds outdoors can cause downdraft in the chimney, but the EcoDamper's mechanical draft counters this.
Spillage elimination. Depressurization in rooms with fireplaces can cause spillage, another dangerous condition that EcoDamper often offsets.
Draft control. During sudden changes in room pressure, EcoDamper’s ADC100 control makes sure the draft remains above the minumum setting - or shuts down the gas supply..
Automatic shutdown. In the event that a safe draft condition cannot be maintained, the ADC100 control shuts down the gas supply for the fireplace.
Energy savings. At the same time, EcoDamper saves energy and meets energy codes by automatically closing off the chimney when the fireplace is not being used.
