have a minimum free area of 1 sq. in./4000 Btu/
hr of total input rating of all equipment in the
enclosure.
See Fig. 3 below.
• Where communicating with the outdoors is
through horizontal ducts, each opening shall have
a minimum free area of not less than 1 sq.in./2000
Btu/hr of total input rating of all equipment in the

2.5. Combustion Air and Vent Piping
The PRESTIGE Solo requires a Category IV venting sys-
tem, which is designed for pressurized venting and
condensate.
The PRESTIGE Solo is certified as a Category IV or Direct
Vent (sealed combustion) appliance. A Category IV ap-
pliance utilizes uncontaminated indoor or outdoor air
surrounding the appliance for combustion. A Direct Vent
appliance utilizes uncontaminated outdoor air piped di-
rectly to the appliance for combustion.
Do not install the PRESTIGE Solo into a com-
mon vent with any other gas or oil appliances.
This will cause flue gas spillage or appliance
malfunction, which will result in substantial
property damage, serious injury, or death.
