necting the interior spaces shall comply with
the Indoor Combustion Air section on page 7.

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

Combustion Air and Vent Piping

The PRESTIGE Solo requires a Category IV
venting system, which is designed for pressur-
ized venting and condensate.
The PRESTIGE Solo is certified per ANSI
Z21.13 as a Category IV or Direct Vent (sealed
combustion) appliance. A Category IV appli-
ance utilizes uncontaminated indoor or outdoor
air (surrounding the appliance) for combustion.
A Direct Vent appliance utilizes uncontaminat-
ed outdoor air (piped directly to the appliance)
for combustion.
BEST PRACTICE

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.
NOTI E
Install combustion air and vent pipe as
detailed in the PRESTIGE Solo Vent
Supplement included in the boiler
installation envelope. Refer to optional
vent kit instructions for additional vent
installation instructions.
DANGER
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.
