3.5.4 Fresh Air System (Ducted Combustion Air)
In some instances compliance with ANSI Z21.13 may not be required, in which case a "fresh air system"
may be used. Consultation with qualified professionals is required to determine whether a "fresh air
system" is suitable for any particular application and in compliance with all applicable codes and
regulations.
All flue gas outlet (exhaust vent) material for a fresh air system must be certified for use with a Category I
Appliance. (Standard B-vent is approved.) The exhaust vent may be run horizontally or vertically. Proper
vent sizing by the vent manufacturer's recommendation must be followed.
