OPERATING YOUR NEW RHFE-556T
■ TO OPEN THE CONTROL PANEL
Open Control Panel Cover with key provided.
■ TURNING ON (For manual operation
please refer to page 21).
Press the ON/OFF button to operate the heater. The
ON indicator will glow green. After approximately 20
seconds the spark generator will be heard before the
burner ignites and the ON indicator glows red,
indicating that the burner is alight. Warm air can be
felt coming from the louvres 15 seconds later.
If the heater does not ignite on initial use, this may be due to air remaining in the gas supply line. The
spark generator will only continue for 15 seconds. After this it will be necessary to press the ON/OFF
button OFF, then ON again.
■ TURNING OFF
Simply press the ON/OFF button to switch off the
heater. The ON indicator will go out. The convection
fan will continue to operate for several minutes after
the burner has gone out in order to cool the appliance.
Do not unplug the appliance while the convection
fan is running.
IMPORTANT NOTE:
DO NOT turn heater off by unplugging at the power point.
The convection fan must continue to run until the appliance cools.

■ FAN FILTER
To protect the room air fan from dust particles or lint, a
filter is situated at the rear of the appliance. When
this filter becomes blocked, the filter indicator will flash
to indicate that it should be cleaned. Clean the filter
weekly during the heating season to avoid
unnecessary strain on the appliance.
Do not remove filter when appliance is operating.
When the filter requires cleaning, clean filter before
using the appliance, or whilst the appliance is not
operating.
If you do not clean the filter at regular intervals and
the filter indicator is allowed to remain flashing, then
the appliance will stop and [14] will flash on the Digital
Display signifying that the inbuilt safety device has
functioned. You must clean the filter before operating
the heater again.
■ HUMIDIFIER TRAY
■ VERTICAL LOUVRE ADJUSTMENT
The warm air flow direction may be altered by
inserting a screwdriver or similar tool and gently
bending the vertical louvre(s) either to the left or the
right.
Note: these louvres are not designed to be
adjusted more than 6 times.
So that you can humidify the air, your Rinnai RHFE-556T is fitted with an enamelled tray at the bottom
of the heater. If you choose to make use of the humidifier tray, it will need filling about once a day
during the heating season. Do not fill the humidifier tray while the heater is running.
The humidifier has the benefit (when filled with water) of raising the humidity in the air. With increased
humidity, the heater can actually be run at a lower temperature while still maintaining the same level of
comfort.
1
To fill the humidifier tray:
Remove the bottom trim panel, below the louvres, by
pulling on both sides. Simply pull the tray forward to
allow it to be filled with water. The warm air will be
humidified as it passes over the water in the tray.
Refit the bottom trim panel after filling the tray. The
RHFE-556T is a very high efficiency appliance,
during operation a small amount of condensation is
produced in the flue system, this drains into the
enamelled humidifier tray.

PRE-SERVICE CHECK
Before asking for a service call please check the following points.
These points are part of the normal operation of the unit.
■ At Ignition:
Heater does not operate.
Warm air does not flow when the burner lights.
Smoke or strange smells are produced on the
first trial light up after installation.
Sharp clicking noises at ignition, or when the
unit cuts down on the thermostat, or goes out.
Is the heater plugged in?
Have the fuses or breaker blown at the switch board?
Is there a power failure?
Is the air filter blocked?
Is anything blocking the outlet for the hot air?
Is the flue blocked?
Is a remote timer fitted and set “ON”.
■ During combustion:
Clunking noise when the thermostat operates.
Unit is not heating room.
Air filter is blocked or the louvres are blocked or
obstructed.
Heater will not re-ignite after overheating.
This is the sound of the solenoid gas valves opening and
closing.
■ When the unit is turned off:
Convection fan continues to run after turning
OFF.
This is to remove the residual heat from the heat
exchanger, the fan will stop when the heater cools down.
■ Other Points:
Steam is discharged from the flue terminal.
Unit cuts off without apparent reason.
Power Failure.
High efficiency appliances tend to discharge water
vapour on cold days, this is normal.
Check whether filters are blocked, dirty filters will cause
the heater to overheat.
Switch OFF, then ON again when power is restored to
re-set controls.
Is the air filter blocked?
Is the set temperature high enough?
Is the warm air outlet blocked by anything?
Are the doors and windows of the room closed?
Allow heater to cool, clean air filter, operate again.
Even after unit has cooled down the heater does not
ignite again. Repair is necessary.
Contact your local agent or Rinnai for a Service call.
The fan is started automatically after a short delay.
This is to allow the heat exchanger to warm up, helping
to avoid cold draughts.
This is caused by grease or oil and dust on the heat
exchanger and will stop after a short time.
This is simply expansion noise from the heat exchanger.

■ TYPES COMPATIBLE WITH EXTENSION KIT
RHFE - 556FTR / 556T
INSTALLING AN EXTENSION KIT
Installing an extension kit requires construction of an air line and the exhaust line. The air line is
connected between the Air Supply Elbow at the rear of the heater and the air inlet port on the Flue pipe.
Similarly, the exhaust line is connected between the joint pipe at the rear of the heater, and the exhaust
port on the Flue pipe.
Caution: Check to see there is no debris in pipe or hose.
■ HOW TO INSTALL
MODEL: RHFE - 556FTR / 556T
Example: Using 2 sets of extension kit and 1 bend kit. Example: Using 2 Metre side pipe kit.

2. How to connect air intake hose
Screw hose joint half of its length onto the air intake hose, then screw another air intake hose into the joint.
The hose can be cut to the required length.
IMPORTANT: The PVC air line is longer than the exhaust line and may need to be cut to size. Be
sure, however, to thoroughly deburr all rough edges.

• The air intake hose and exhaust pipe can
also be screwed onto the wall using the pipe
clamp and the nut.
With the exhaust pipes inserted into the ends,
bend the bent pipe to the angle required for
installation.
This part is mainly used for curves and for
connection to vent terminal.

■ CAUTIONS
1. Maximum extendable length
FOR BEST ROOM AIR HUMIDITY, KEEP
WATER IN THE HUMIDIFIER TRAY.
2. To prevent water condensation
Condensed water
may accumulate
here, and cause a blockage
preventing combustion.
MAXIMUM FLUE LENGTH 7 METRES.
Reduce length 1 metre for each bend used.
(e.g. 4 metres, 3 bends).
• The bend where the hose and pipes leave
the body is not counted.
• The air intake hose should run along the
exhaust pipe.
3. Condensed water formed by
combustion, will run back to the
unit, and may overflow from the
condensation pan if pipes are
longer than 2.5m. Therefore,
pipes exeeding these lengths
should be made to drain to the
outside by giving their horizontal
portions 75mm or more downward
and outward slope.
CAUTION
Never allow the exhaust pipe to sag, as
condensed water may accumulate and
cause incomplete combustion.
75mm slope(approximate)
Less than 2.5m
– 32 –
4. Wherever the air intake hose and exhaust pipe
run sideways, try to have the exhaust pipe on
top (to prevent the air intake hose from sagging
onto the exhaust pipe).
