Description

The flueing for internal
water heaters is a coaxial
design. It has a stainless
steel inner pipe to discharge
products of combustion and
a thermoplastic outer pipe for
air supply to the appliance.

The Rinnai INFINITY® internal
gas hot water heaters are room
sealed appliances—sealed
from the room as it takes
air for combustion from the
outside, and expels products
of combustion outside. No
ventilation in the space where
the water heater is installed is
required.

Each Rinnai INFINITY® water
heater is flued individually.
