Flue components
1
Ember adaptor (R3653)
Refer p. 30 for clearance to
combustible information for the
Ember adaptor.
Maximum length can’t be more
than 600 mm due to the heat
from the colinear flexi flues.
Horizontal wall terminal (R3650)
2
Horizontal flashing kit (R3646)
3
Flue pipe(s) or flue extension
The horizontal run of flue pipe
must have a 20 mm
rise
for every
1 m
towards
the flue termination.
NEVER allow the flue pipe to
run downwards towards the flue
terminal. A downwards slope
can trap heat and become a fire
hazard.
4
Flue elbow 90
°
(R3643)
Maximum number of 90° bends is
one.

If installing the Rinnai Ember into a purpose built chimney breast or chase,
which is not open to the roof space of the building, you will need to add
cavity vents.
Heat from the fire lost through the outer skin of the appliance or the flue
system will not be able to adequately vent. This can lead to a build up of excess heat in the cavity.
In some cases the fire may overheat and the overheat safety mechanisms may operate.
Adding two vents of at least 200 cm
2
, one at floor level, and one at ceiling level, will allow adequate
airflow in a cavity of approximately 1.2 m wide x 2.4 m high and 0.8 m deep. With an additional
benefit that the ventilation of the cavity will return some of this heat into the room.
