CHAPTER 2 - COMBUSTION AIR & VENTING
2.2. Ventilation and Combustion Air Require-
ments - Direct Vent
A Direct Vent appliance utilizes uncontaminated out-
door air piped directly to the appliance for combustion.
For Direct Vent installations involving only the IN-
STINCT, in which the minimum service clearances are
maintained as listed in Section 1.5 on page 3, no
ventilation openings are required, but may be neces-
sary to equalize the air pressure with the outside.
For Direct Vent installations involving only the INSTINCT,
in which the minimum service clearances are not main-
tained as listed in Section 1.5 on page 3, the space
/ enclosure must provide two openings for ventilation.
The openings must be sized to provide 1 square inch of
free area per 1,000 BTUH of boiler input. The openings
shall be placed 12 inches from the top of the space and
12 inches from the oor of the space.
For installations in which the INSTINCT shares the
space with air movers (exhaust fan, clothes dryers,
replaces, etc.) and other combustion equipment (gas
or oil) the space must be provided with adequate air
openings to provide ventilation and combustion air
to the equipment. To properly size the ventilation /
combustion air openings, the installer must comply
with the National Fuel Gas Code (NFPA 54 / ANSI
Z223.1) for installations in the U.S. or CAN/CSA B149.1
for installations in Canada.
The space must be provided with ventilation
/ combustion air openings properly sized for
all make-up air requirements (exhaust fans,
clothes dryers, fireplaces, etc.) and the total
input of all appliances located in the same
space as the INSTINCT, excluding the input
of a Direct Vent INSTINCT which uses com-
bustion air directly from the outside, thus
additional free area for the openings is not
required. Failure to provide or properly size
the openings can result in substantial prop-
erty damage, serious injury, or death.
WARNING
2.3. Ventilation and Combustion Air Require-
ments - Category IV
A Category IV appliance utilizes uncontaminated indoor
or outdoor air surrounding the appliance for combus-
tion.
In order to reduce the potential risks associated
with indoor contaminates (see list in Section
2.1 on page 5), flammable vapors and tight
housing construction with little or no infiltration
air, it is recommended to pipe uncontaminated
combustion air directly from the outdoors to
the appliance. This practice also promotes high-
er system efficiency by reducing heated indoor
air from being exhausted from the house and
replaced by cold infiltration air into the house.
For installations in which the INSTINCT shares the
space with air movers (exhaust fan, clothes dryers,
replaces, etc.) and other combustion equipment (gas
or oil) the space must be provided with adequate air
openings to provide ventilation and combustion air
to the equipment. To properly size the ventilation /
combustion air openings, the installer must comply
with the National Fuel Gas Code (NFPA 54 / ANSI
Z223.1) for installations in the U.S. or CAN/ CSA B149.1
for installations in Canada.
The space must be provided with ventilation
/ combustion air openings properly sized for
all make-up air requirements (exhaust fans,
clothes dryers, fireplaces, etc.) and the to-
tal input of all appliances, including the IN-
STINCT when located in the same space. Fail-
ure to provide or properly size the openings
can result in substantial property damage,
serious injury, or death.
