16.0) VENTING
Failure to do so may result in death, serious injury, property damage or illness
from Carbon Monoxide poisoning.
Heaters installed in an unvented mode require a minimum ventilation flow of
4 CFM per 1,000 Btu/hr of total installed capacity.
In buildings with airborne contamination the heater must be installed with
fresh air for combustion.
