Air Requirements

WARNING
Breathing Hazard - Carbon Monoxide Gas
• Water heater must be vented to outdoors.
• Vent must be installed by a qualified technician
using the installation instructions.
• Examples of a qualified technican include: gas
technicians, authorized gas company personel,
and authorized service persons.
• Failure to so do can result in death or carbon
monoxide poisoning.
Breathing carbon monoxide can cause brain damage or death.
Always read and understand instruction manual.
Combustion and ventilation air must be provided as per
the current edition of "Installation Code for Oil-Burning
Equipment" (B139) .
An adequate supply of combustion and ventilation air is
required to:
•
Ensure proper combustion.
•
Reduce risk of property damage, severe bodily injury or
death from possible flue gas leakage and carbon monoxide
emissions.
Satisfactory combustion cannot be sustained in an area that
is not provided with fresh air. Fresh air contains oxygen that
is necessary for proper combustion. If necessary, sufficient
fresh air must be drawn in from outside of the enclosure. Lack
of adequate fresh air supply may cause a poor flame. The
current edition of CSA-F300 provides methods for evaluating
if adequate air is available.
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.

The following types of installation (not limited to the following)
will require outdoor air for combustion due to chemical
exposure and may reduce but not eliminate the presence of
corrosive chemicals in the air:
•
beauty shops
•
photo processing labs
•
buildings with indoor pools
•
water heaters installed in laundry, hobby, or craft rooms
•
water heaters installed near chemical storage areas
Combustion air must be free of acid-forming chemicals such
as sulfur, fluorine, and chlorine. These elements are found
in aerosol sprays, detergents, bleaches, cleaning solvents,
air fresheners, paint, and varnish removers, refrigerants,
and many other commercial and household products. When
burned, vapors from these products form highly corrosive acid
compounds. These products should not be stored or used
near the water heater or air inlet.
Combustion and ventilation air requirements are determined
by the location of the water heater. The water heater may be
located in either an open (unconfined) area or in a confined
area or small enclosure such as a closet or small room.
Confined spaces are areas with less than 50 cubic feet for
each 1,000 Btu/hr (4.8 cubic metres per kilowatt) [7000 cubic
feet for each 1 gal./hr] of the total input for all combustion
appliances.

Vent and Exhaust Connections

The vent and exhaust connections must comply with the
requirements of the current edition of "Installation Code for
Oil-Burning Equipment" (B139) .
