Venting Introduction

The CC40LE/CC40RE uses the "balanced flue" technology Co-Axial system. The inner liner vents products of combustion to the outside while the outer

liner draws outside combustion air into the combustion chamber thereby eliminating the need to use heated room air for combustion and losing warm room

air up the chimney.

Note: These flue pipes must not be connected to any other appliance.

The gas appliance and vent system must be vented directly to the outside of the building, and never be attached to a chimney serving a separate solid fuel or

gas burning appliance. Each direct vent gas appliance must use it's own separate vent system. Common vent systems are prohibited.
