2.0 Combustion Air Venting
2.2 Ventilation and Combustion Air
Requirements - Direct Vent
A Direct Vent appliance utilizes uncontaminat-
ed outdoor air (piped directly to the appliance)
for combustion.
For Direct Vent installations, involving only
the PRESTIGE Solo, in which the minimum
service clearances are maintained as listed on
page 4, no ventilation openings are required.
For Direct Vent, zero clearance installations
involving only the PRESTIGE Solo, the space
/ enclosure must provide two openings for ven-
tilation. 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 floor of the space.
For installations in which the PRESTIGE Solo
shares the space with air movers (exhaust fan,
clothes dryers, fireplaces, etc.) and other com-
bustion equipment (gas or oil) the space must
be provided with adequate air openings to pro-
vide 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 CSA B149.1 and B149.2 for installa-
tions in Canada.
The space must be provided with venti-
lation / combustion air openings proper-
ly 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 PRES-
TIGE Solo, excluding the input of a
Direct Vent PRESTIGE Solo which uses
combustion air directly from the outside,
thus additional free area for the open-
ings is not required. Failure to provide
or properly size the openings could
result in severe personal injury, death or
substantial property damage.
2.3 Ventilation and Combustion Air
Requirements - Category IV
A Category IV appliance utilizes uncontami-
nated indoor or outdoor air (surrounding the
appliance) for combustion.
In order to reduce the potential risks
associated with indoor contaminates
(listed on page 5), flammable vapors and
tight housing construction (little or no
infiltration air), it is recommended to
pipe uncontaminated combustion air
directly from the outdoors to the appli-
ance. This practice also promotes higher
system efficiency by reducing heated
indoor air from being exhausted from
the house and replaced by cold infiltra-
tion air into the house.
For installations in which the PRESTIGE Solo
shares the space with air movers (exhaust fan,
clothes dryers, fireplaces, etc.) and other com-
bustion 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 CSA B149.1 and
B149.2 for installations in Canada, as referenced
in this section of the manual and titled Methods
of Accessing Combustion Air into a Space.
The space must be provided with venti-
lation / combustion air openings proper-
ly sized for all make-up air requirements
(exhaust fans, clothes dryers, fireplaces,
etc.) and the total input of all appliances,
including the PRESTIGE Solo when
located in the same space. Failure to pro-
vide or properly size the openings could
result in severe personal injury, death or
substantial property damage.
