2.15 DUCTED COMBUSTION AIR
See the
Innovation-Edge Venting and Combustion Air Design Guide
(TAG-0090, GF-5056).
The AERCO Innovation Water Heater is UL listed for 100%-ducted combustion air. For ducted
combustion air installations, the inlet air
ductwork must then be attached directly to the unit’s air
inlet.
In a ducted combustion air application, the combustion air ducting pressure losses must be
considered when calculating the total maximum allowable venting run. When using the heater in
a ducted combustion air configuration, each unit must have a minimum 6-inch (15.24 cm)
diameter connection at the unit.
