Flue spigot dimensions

The Rinnai INFINITY flue spigot for the N56kWi
is fixed and cannot be adjusted.

Joint connection

Flue connections must be firmly pressed
together so that the gaskets form an airtight
seal.
To ensure optimum joint connection it is
recommended to secure with 4 x 12.5 mm
(#8 x ½ ") self tapping screws.

Appliance connection

All N56kWi flueing will start with either the
horizontal adapter (part of the horizontal thru wall
kit) or the vertical adapter. This reduces the flue
diameter from Ø80/120 mm to Ø60/100 mm.
Insert the male end of the adapter into the
female flue spigot on the top of the water heater.
Secure in place with self tapping screws.

Condensate

The condensate trap collects any condensate
from the flue and prevents condensate from
entering the water heater and causing damage.
Condensate is a by-product of gas combustion
and is mildly acidic. For this reason copper tube
and fittings must not be used as it will corrode.
Instead Rinnai recommends plastic pipe and
fittings such as UPVC or PE.
For further information refer to the Rinnai
INFINITY N-Series installation guide.
