DO SO CAN CAUSE DEATH FROM
CARBON MONOXIDE POISONING.
Adequate facilities for providing air for
combustion and ventilation must be
provided in accordance with section
5.3, Air for Combustion and
Ventilation, of the National Fuel Gas
Code, ANSI, Z223.1 latest edition or

flow of air to the furnace.
IMPORTANT: Air for combustion and
ventilation must not come from a
corrosive atmosphere. Any failure due
to corrosive elements in the
atmosphere is excluded from warranty
coverage.
