Clearance / Framing and Venting Configurations
The G800EC is designed to allow for unique installation options—depending on the desired finish.
Please review the options and follow the specific clearance, framing, and finishing options for that application.
The applications are as follows:
Cool Wall application: combustible materials can be installed right up to the fireplace opening with this option.
Clean Front application: non-combustible required when installing materials right to the fireplace opening with this option.
Outside Finish application: non-combustible materials required and the unit is finished to the edge of the fireplace or with either a finishing trim or faceplate..

Framed Opening must be at least 2 3/8” tall, and at least 33 3/8” wide to accomodate the Chase vent. The top of the Chase vent opening
must be 1.5” or less from the top of the chase enclosure. Fasten the Chase vent with screws and construction adhesive.
If the chase vent is not being used, a minimum 66in2 opening in the enclosure is required to maintain safe operating tempera-
tures. This can be achieved in a number of ways including a reveal at the top of the chase.
