CRITICAL WARNING

The Suncourt dryer vent kit is only approved for installation for electric clothes dryers.

Installation of the Suncourt dryer vent kit for gas clothes dryer may only be performed by a certified and professional installer. A provision must be made for a fresh air supply to the gas fired clothes dryer to make up for air removed from the space around the dryer.

The installer must verify and certify that there is absolutely no negative air pressure.  Failure to do so will draw deadly carbon monoxide from the gas dryer exhaust into the home.  This creates a deadly condition.

* NEVER expose your Centrax Centrifugal Fan to airflow temperatures exceeding 140°F (60°C).
* Make sure all electrical wiring conforms to all applicable codes and standards. If you are not familiar with electrical installations, consult a qualified electrician.
