Combustion Air and Venting
Outdoor Opening(s) Location. Outdoor open-
ing(s) shall be located in accordance with the
Outdoor Combustion Air section.
Outdoor Opening(s) Size. Outdoor opening(s) shall
be calculated in accordance with the following:
-
The ratio of the interior spaces shall be
the available volume of all communi-
cating spaces divided by the required
volume.
-
The outdoor size reduction factor shall
be 1 minus the ratio of interior spaces.
-
The minimum size of outdoor open-
ing(s) calculated in accordance with the
above outdoor air section multiplied by
the reduction factor.
The minimum
dimension of air openings shall not be
less than 3 in.
Do not install the PRESTIGE into a com-
mon vent with other gas or oil appliances.
This may cause flue gas spillage or appli-
ance malfunction, resulting in possible
severe personal injury, death or substan-
tial property damage.
Combustion Air and Vent Piping
The PRESTIGE requires a Category IV vent-
ing system, which is designed for pressurized
venting and condensate.
The PRESTIGE is certified per ANSI Z21.13
as a Category IV or Direct Vent (sealed com-
bustion) appliance. A Category IV appliance
utilizes uncontamined indoor or outdoor air
(surrounding the appliance) for combustion. A
Direct Vent appliance utilizes uncontaminated
outdoor air (piped directly to 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.
Install combustion air and vent pipe as
detailed in the PRESTIGE Vent Sup-
plement included in the boiler installa-
tion envelope.
Verify installed combustion air and vent
piping are sealed gas tight and meet all
provided instructions and applicable
codes, failure to comply will result in
severe personal injury of death.
