Venting Introduction
The ACB60E 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.

Refer to the "Vent Restrictor Position" section for details on how to change the vent restrictor from the factory setting of Set 0 to Set 2 if required.
Note: For horizontal terminations the Regency Direct Vent Flex System may be used for installations with a maximum continuous
vent length of up to 3 meters. If longer runs are required, rigid pipe must be used.
•
Maintain clearances to combustibles as listed in "Clearances" section
•
Horizontal vent must be supported every 0.91 meters.
•
Firestops are required at each floor level and whenever passing through a wall.
