ENERVEX IntelliDraft™ - the Intelligent Draft Solution

ENERVEX IntelliDraft - how it works

The IntelliDraft connects a draft and safety controller, the ADC150 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 until the draft set-point has been reached and the integrated draft protection switch closes.
At this point, the controller allows the fireplace to fire by opening the gas valve. During operation of the fireplace the control continues to monitor the draft and will maintain the proper draft set-point by modulating the chimney fan speed whenever needed.
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 building by the chimney fan; then the control discontinues chimney fan operation and closes the damper.
If for any reason the 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 IntelliDraft system component

Safety is always important. The IntelliDraft creates the safest operation for any gas-fired fireplace or decorative appliance, and exceeds even the building codes' strictest safety requirements.

Protects against downdrafts
Eliminates spillage and CO release due to building depressurization
Automatically shuts down fireplace operation, if conditions are unsafe.

Today's fireplace designs challenge the traditional venting system design.
IntelliDraft opens up many new design options while allowing for a larger view area of the fire and a more natural look.

Freedom to integrate almost any fireplace design
Eliminates the need for glass doors
Enables chimney designs that defy traditional design rules

Energy savings
A fireplace uses a lot of energy. Not only from the gas fire but also from the conditioned air that is constantly vented to the outside. IntelliDraft puts an end to this waste of energy.

Chimney is closed when the fireplace is not used
The draft is never excessive which saves fuel
Perfect operating conditions eliminate unnecessary carbon emissions.

MFD Product Info PDF

MFD Installation PDF

  MFD Mechanical Fireplace Damper

A chimney top mounted automated damper for use with gas fireplaces and model RS Chimney Fan. The MFD prevents excess heat from escaping through the chimney when the fireplace is not in use. The ultra low profile MFD comes equipped with an actuator that is interlocked to the ADC 100 so it only opens when the fireplace is in use and draft is proven.

  ADC150 Fan Control

The ENERVEX ADC150 is a Modulating Fan Control used with up to 2 appliances to monitor and maintain a constant draft or pressure in a chimney or duct. The ADC150 can be used with models RS, RSHT, and GSV fans. It can control the fan speed directly or via a Variable Frequency Drive (VFD, sold seperately). The ADC150 is typically used to control the draft of a gas-fired, sealed fireplace or water heaters.

The ADC150 monitors the draft in a chimney system via a connection to a pressure transducer (XTP2) attached to the chimney, and maintains the draft by modulating the fan speed. It provides a 10-120V AC power to single phase fans and 0-10V DC control signal to control 3-phase fans via a variable  frequency drive.
