2.15 DUCTED COMBUSTION
The AERCO Innovation Water Heater is UL listed for 100%-ducted combustion. For ducted
combustion installations, the screen
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
taken into account when calculating the total maximum allowable venting run. See the AERCO
Innovation Venting and Combustion Air Guide, GF-5050. When using the heater in a ducted
combustion air configuration, each unit must have a minimum 6 inch diameter connection at the
unit.
