Isokern Maximus Linear Series Gas Fireplace
The ENERVEX MFD is a low profile, automated fireplace damper. It is for use in conjunction with an ENERVEX ADC100
control and RS model chimney fan as part of the EcoDamper System. or with an ADC150 control and RS model chimney
fan as part of the IntelliDraft System. It prevents excess heat from escaping through the chimney when the fireplace is
not in use.
The MFD is designed for chimney top installations and is for use with gas fireplaces only.
The MFD is powered by a 120 or 24 VAC actuator. The actuator is interlocked to the control so it only operates when
the fireplace is in use and the fan is running. When there is a call for heat from the fireplace, the ADC100 or ADC150
control begins its operational sequence to open the damper and start the chimney fan. Once the damper opens and there
is sufficient draft in the chimney, the control releases the gas valve for fireplace operation.
The actuator has two end switches to prove damper position (open or closed) and is equipped with the Enerdrive fail safe
system to open the damper in the event of an electrical or mechanical failure.
The damper is rated for temperatures up to 575oF (300oC). The damper is sized to provide sufficient clearance between
the damper blade and the fan inlet when open. The MFD is constructed of 18 gauge, type 304 stainless steel.
System installation must conform to the requirements of the authority having jurisdiction. When required by the authority
having jurisdiction, the installation must also conform to the NFPA31, NFPA54 or NFPA211.
All electrical wiring must be in accordance with the requirements of the authority having jurisdiction or, in
absence of such requirements, with the National Electric Code, NFPA 70.
