3.2 Combustion Air
NeoTherm boilers and water heaters must have provisions
for combustion and ventilation air in accordance with the
applicable requirements for Combustion Air Supply and
Ventilation in the National Fuel Gas Code, ANSI Z223 1; or in
Canada, the Natural Gas and Propane Installation Code, CSA
B149.1. All applicable provisions of local building codes must
also be adhered to.
A NeoTherm unit can take combustion air from the space
in which it is installed, or the combustion air can be ducted
directly to the unit. Ventilation air must be provided in either
case.
