spark generator will be heard
before the burner ignites and
the indicator will then glow red.
When the heater warms up the
fan will automatically start.
To turn the heater off, press the
ON/OFF button, the indicator
light will go out. The fan will
continue to operate to cool the
appliance and then stop.
Set times
Selects clock, timers, or
temperatures (1005FT model
only) for adjustment or
programming.
Temp and time
Increases or decreases the
temperature as well as changing
the hours or minutes when in
programming mode.
Override
Temporarily changes operation
from ON to OFF or OFF to ON
until the next programmed
setting is reached.
Timer 1 and Timer 2
Displays which timer is
operating.
Child lock
Locks all controls when pressed
except OFF. Hold for two
seconds to deactivate. If the
child lock is pressed while the
heater is off all functions will be
locked, including turning the
heater on, until it is deactivated.
Filter
Indicates the filter needs
cleaning. If you do not clean
the filter at regular intervals and
the filter indicator is allowed to
remain flashing, the appliance
will stop and the display will
show error code 14. The filter
will need cleaning before the
appliance can be turned back
on (refer p. 11).
Clock and timer indicators
When programming, the
indicators will glow to indicate
what is being programmed.
The 1005FT model also has a
‘Temp’ indicator that indicates
the set temperature for the
timer that is being set.
Display window
Shows either the time of day,
temperatures or coded error
message.
Adjusting the room
temperature
Pressing the up and down
arrows will change the preset
temperature by 1 °C. The
temperature will be shown in
the display window. The room
temperature sensor is located
behind the Energysaver so the
temperature on the display may
vary slightly from the actual
room temperature.
The temperature can be preset
to:
• L (low)
Unit operates on the lowest
burner setting.
• 16-26 °C
Unit will modulate, and in
some instances turn off and
on, to maintain the selected
temperature.
• H (high)
Unit operates on the
highest burner setting.
The ‘L’ and ‘H’ settings are not
normally used as it means the
heater operates without a set
temperature.
Economy
Prevents the room overheating,
reduces gas consumption, and
ultimately saves energy. Once
the room has reached the
desired temperature, the unit
automatically begins gradually
reducing the set temperature
(set temperature on digital
display will stay the same).
This reduction is normally not
noticeable.
How it works
After the room reaches the
set temperature, the set
temperature will automatically
start decreasing, dropping
by a maximum of 1 °C in 30
minute blocks, until comfort
control is reached. When in
comfort control the unit alters
combustion and fan speed to
keep the room at a comfortable
temperature.
The ‘Economy’ function will
not operate when the set
temperature is less that 16 °C or
above 26 °C.

Important
Clearances while the heater is operating
This appliance must not be installed where
curtains or other combustible materials could
come into contact with it. The clearances
shown
must be
maintained.
Floor protection
Energysavers discharge a large volume of warm
air at a low level. Heat over time may affect
the appearance of some flooring materials,
such as, carpet, vinyl, cork, or timber. This may
be amplified if the
air contains cooking
vapours or cigarette
smoke. To avoid
this occurring, it is
recommended that a
mat be placed in front
of the appliance.
Outside flue terminal
Keep flammable materials, trees, shrubs, etc.
away from the flue terminal. In areas subject
to heavy snowfall, keep snow clear of the flue
terminal at all times.
Outside flue terminal
On cold days steam may be discharged from
the flue terminal. This is normal with high
efficiency gas appliances like the Energysaver
range and does not indicate a fault.
Humidifier tray
Do not overfill—there is a maximum water level
indicator in the tray, also do not fill while the
heater is operating (more information on p. 10).
250 mm
1000 mm

Snow
Filters
During peak operating periods the filters
should be cleaned weekly. If the ‘Filter’ warning
indicator flashes on the control panel display,
immediately turn off the appliance and clean
filters before starting again.
The Energysavers must not be built into bookcases or walls etc.
Energysavers are not recommended for installations in unusually dusty environments such as hair salons
or where there are a large number of pets—this will cause continual blockage of the filter(s).

Humidifier tray
Your heater is fitted with an enamel humidifier
tray. To fill the tray, open the access panel as
shown in the diagrams below. Pour water into the
tray, or in the case of the 1005FT, pour water into
the filler spout built into the access panel.
RHFE-309FT / 559FT/561FT
RHFE-1005FT
If you notice water in the humidifier tray, but
you have not placed any in there do not be
alarmed, this is normal. This will be condensate
from the flue system—designed to drain into the
humidifier tray.
If you are using the humidifier tray, it will need
filling approximately once a day.
• Do not fill the humidifier tray while the heater
is on, it will be very hot and could cause
burns—turn the heater off and wait at least
five minutes.
• Do not operate the heater without the
humidifier tray in place.
Vertical louvre adjustment
When the heater is turned off the warm air flow
direction may be altered by carefully inserting a
screwdriver or similar tool and gently bending the
vertical louvres to the left or right.
The louvres are not designed to be adjusted more
than six times as they will weaken and break.
Power failure
If a power failure occurs for at least 0.2 seconds
the unit will turn itself off. After power has
been restored the unit will automatically turn
on again—you may need to reset the clock
depending on the length of the power cut.
If timer settings have been programmed the
system memory will retain the timer settings, but
the clock will stop at the time the power goes off
and will be slow by however long the power has
been off.
Preheat
Automatically functions in conjunction with
the timers. When a timer is selected, the heater
may operate anywhere within an hour prior
to the programmed on time. The preheat
function ensures the room reaches the desired
temperature by the programmed start time.

Care and maintenance
Before cleaning any part of the heater ensure it is
turned off and has cooled down. All parts of the
heater can be cleaned using a soft damp cloth and
mild detergent—do not use solvents.
If the humidifier tray gets dirty it can be washed in
warm soapy water.
Fan filter(s)
To protect the appliance
from dust or lint a filter
(two in the case of the
1005FT) is located at the
rear of the appliance. If the
filter becomes blocked the
filter indicator will flash to
indicate that it should be
cleaned.
The build up of dust on the filter reduces the air
flow through the heater. This reduces the heater’s
efficiency and can lead to the appliance shutting
down. Regular (weekly) filter cleaning during the
heating season will stop this from happening.
If you do not clean the filter at regular intervals
and the ‘Filter’ indicator is allowed to remain
flashing, the appliance will stop (ON indicator will
flash and the display will show error code 14). The
filter will need to be cleaned before operating the
appliance again.
• Do not remove the filter when the appliance is
operating.
• Do not use the heater with the ‘Filter’
indicator flashing as this may cause the
appliance to overheat.
Cleaning the fan filter(s)
• Dry dust/lint: Use a duster or vacuum to
remove the dust.
• Oily residue: Wash using a mild detergent,
drain off the water, and dry.
Ensure the fan filter is fitted back into the
appliance after cleaning. DO NOT operate
the appliance without the filter in place.
Maintenance and servicing
Rinnai has a maintenance, service and
spare parts network with personnel
who are fully trained and equipped to
give the best advice on your Rinnai
appliance. If your appliance needs
maintenance or servicing for repair, please call
Rinnai (0800 746 624).
For reliable operation your Rinnai Energysaver,
including inspection of the flue section, should
be checked by a licensed tradesperson every
two years. If located in a particularly dusty area
or subject to excess lint, for example dog hair or
where there are newly laid carpets, then annual
servicing would be beneficial.
Regular maintenance and servicing is not covered
by the Rinnai warranty.
If you have any other faults or problems, please
contact your installer or call Rinnai.
WARNING

12 | Energysaver operation and installation guide 02-15
Troubleshooting
Check the following information before making a service call. If you are still unsure or
concerned after reading this section, please contact Rinnai.
Using the heater for the first time, or after a long period of non use
The heater may not start the first time it is operated due to air in the gas pipes. If ignition
does not occur within approximately one minute the heater will attempt to start again.
If it does not start the unit will switch itself off automatically—this is a safety feature. Try
switching the heater back on if this occurs.
What’s happening Explanation and/or possible solution
Warm air not coming from the heater when is
starts.
The heater’s fan will start automatically after
a short delay. This is to allow the appliance to
warm up and to stop cold draughts.
Smoke or strange smells coming from the heater
after it has been installed.
This is caused by grease, oil, or dust within the
appliance. It will stop after a short time.
Clicking noises when the heater starts or stops,
or changes to a higher or lower setting.
This is expansion and contraction of the heat
exchanger and is a normal part of operation.
Clunking noise when the thermostat operates. This is the sound of the gas valve opening and
closing to regulate the flow of gas and is a
normal part of operation.
Fan continues to run after the heater is turned
off.
This is to remove heat from the appliance and
will stop once the heater has cooled down.
Timer(s) do not operate at the set time. Check the timers are set correctly as they may
be inactivated or incorrectly programmed.
Timer operates for a short time then cuts out. The room temperature may be higher than the
set temperature. Increase the set temperature.
Smell of gas. There may be a small leak in the appliance. Turn
the heater off and contact Rinnai.
Heater doesn’t start. Check power cord is plugged in properly.
Check Child Lock isn’t on.

Error codes
The Energysaver range has built-in technology to continually monitor its own
performance. If a fault occurs, an error message will flash on the digital display
on the control panel. This assists with diagnosing the fault and may enable you
to overcome a problem without a service call.
In all cases, you may be able to clear the error by turning the heater off and on again. If the
error code remains or returns when the heater is used again, contact Rinnai.
Faults caused by insufficient gas supply, gas quality, installation or operation errors are not
covered by the Rinnai warranty.

Positioning, gas, and electrical supply
Positioning
The main points governing the location of the heater are flueing and warm air distribution. The heater
must not be installed where curtains or other combustible materials could come into contact with the
appliance. In some cases curtains may need restraining—refer p. 7 for clearance information.
This heater is not recommended for installations in unusually dusty environments such as hair salons or
where there are a large number of pets—will cause continual blockage of the fan filter.
Gas supply
The gas supply terminates outside the heater at the rear of the appliance. The gap required between the
wall and heater body is 85 mm for the standard rear panels (115 mm for the 1005FT) or 200 mm for the
back spacer kit.
Gas piping must consider the gas input to this appliance as well as other gas appliances in the building.
An approved sizing chart such as the one in AS/NZS 5601.1:2013 should be used.
All foreign materials such as filings must be purged from the gas supply as they may cause the gas
control valve to malfunction.
Electrical supply
The electrical connection is to the right hand side of the heater (passes out of the rear of the appliance).
A 3-pin plug with a 1500 mm power cord is supplied, this must be connected to a dedicated earthed
power point. The power point must not be above the unit as this is a potential fire hazard.
Alternatively the appliance can be direct wired if the power supply is to be concealed. The electric
isolation switch MUST BE accessible after the appliance has been installed. Consult a qualified electrician
if direct wiring is required as it must comply with the requirement of AS/NZS 5601.1:2013 and
AS/NZS 3000 and any other relevant local regulations.
If the supply cord is damaged and requires replacing, it must be replaced by a licensed tradesperson.
This must be a genuine replacement part available from Rinnai.

Energysaver operation and installation guide 02-15 | 19
Energysaver ueing guidelines
Every Energysaver heater requires a flue system that will draw effectively and
clear flue products safely under all potential wind and climatic conditions.
It is the responsibility of the
installer to ensure that the
appliance is provided with an
effective flue. Some guidelines
to assist with flue design are
listed below. These must be
read and modified as necessary
with reference to the particular
installation.
All Rinnai Energysavers must
be installed with an approved
Rinnai Energysaver flue system.
Approved flue components are
detailed in this guide.
Clearance to combustibles
All Energysaver flueing
components have zero
clearance EXCEPT for the elbow
section of the ESKIT03, and
ESELBOWB. These components
require a minimum clearance
of 25 mm from combustible
materials.
Condensate trap
A condensate trap is required
for all vertical installations to
ensure condensate generated
during combustion is trapped
and prevented from entering
the chamber of the heater.
2°fall to wall terminal
For direct, sideways, and down-
and-out installations, there
must be a continuous fall of
at least 2° to the wall terminal
(equates to 20 mm per metre).
The Energysaver AA/A direct
mushroom flue kits have an
inbuilt 2° fall, and the wall plate
of the ESDFK kit has a 2° offset.
Flue terminal locations
Must be compliant with
AS/NZS 5601.1:2013.
• Do not flue into natural
draught flues or fireplaces.
• Do not flue into other
rooms, roof spaces, or
under floor spaces.
Flue terminal must be
positioned away from
flammable materials.
In areas subject to heavy
snowfall, keep snow clear of the
flue terminal at all times.
Flashings
Flashings are not part of the flue
kit and must be specified.
Vertical terminations: Flue
cowl clearance
To ensure products of
combustion are cleared,
adequate clearance from the
building is required.
The flue cowl should have a
500 mm clearance from any
part of the building. This also
applies to steeped and pitched
roofs which should be clear of
the ridge line. Lesser clearances
may provide perfectly adequate
flue systems depending on
the installation. Minimum
clearances are shown in AS/NZS
5601.1:2013.
Maximum flue length and
number of bends
Max. flue length = 9 m
Max. number of bends = 3
One 90 ° bend equals 1 m. For
every 90 ° bend the overall
length must be reduced by 1 m.
For example, if an installation
has three 90 ° bends, the
maximum flue length can be
6 m.
The flue transition connection
for the ESKIT03 and ESELBOWB
is counted as a 90 ° bend.

FLUEING OPTION DESCRIPTION FLUE COMPONENTS NEEDED
Direct and direct extended flueing
Direct through-the-wall flueing for walls
75-385 mm thick.
Flue can be extended if wall thickness is
greater than 385 mm using the ESDFK and
additional lengths of ESPIPE900.
A: Direct
- R1350, mushroom flue kit for walls 75-115 mm
- R1351, mushroom flue kit for walls 115-240 mm
- ESDFK1, straight horiz. kit for walls up to 385 mm
B: Direct extended
- ESDFK1+ ESPIPE9002
Horizontal (sideways extension) flueing
Flue runs along the left or right hand side
of an internal wall behind the heater.
If retrofitting the flue can be boxed in
along the floor or behind a 125 mm false
wall. This installation requires additional
clearance off the wallback spacer kit
required.
Sideways in-wall
- ESDFK1+ ESELBOWB + ESPIPE9002
Sideways front-of-wall
- Back spacer kit + ESDFK1+ ESPIPE9002
Through-wall (vertical extension) flueing
Flue runs directly from the appliance
to a vertical termination point on the
roof. Typical installation examples for
this type of flue configuration is for
Energysavers installed against solid brick
walls, or where there are flue clearance
restrictions.
Vertical termination

ESROOFCOWL
In-wall (vertical extension) flueing
Flue is installed within a stud wall
(minimum cavity depth of 90 mm) and is
run vertically. This type of installation is
usually completed at the framing stage.
A: Direct
ESKIT03 + ESPIPE9002+ ESROOFCOWL
B: Offset
ESKIT03 + ESPIPE9002+ ESBEND3x 2 + ESROOFCOWL
Down and out flueing
Flue runs below floor level to an
external termination point (must
have a continuous fall of 2 ° to drain
condensate). Ideal for Energysavers that
need to be located in a central position of
a building.
If not going in-wall, flue configuration
requires additional clearance off the
wallback spacer kit required.
