Flueing options and suitability
1
Direct
flueing:
inside of an external wall with a maximum thickness of 430 mm (EF models) and 485 mm (XR/HD
internal models.
Horizontal extension flueing: The same as direct flueing with additional pipe required due to the
longer horizontal distance.
Vertical straight flueing: Installations where the internal unit is flued vertically through the roof.
Combination vertical and horizontal flueing: A combination of all the above.
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.
