CARE AND MAINTENANCE
CLEANING
Your heater needs very little maintenance, but the following information will help you to keep it looking good and
working efficiently.
FILTERS
WARM AIR VENT
It is important that the Warm Air Discharge Vent be kept clear of any obstructions as this will cause your heater
to operate less efficiently. When an obstruction is detected the Blockage Indicator LED which is located next to the
Receiver Window will illuminate RED and the combustion state reduces to front burner, low operation only.
Removing the obstruction will allow normal heater operation to be resumed.
DO NOT attempt to clean the heater while the appliance is hot or operating.
All parts of the heater can be cleaned using a soft, damp cloth.
DO NOT use solvents or abrasives to clean any parts.
DO NOT spray aerosols in the vicinity of the heater whilst in operation.
DO NOT place any articles on or against this heater.
DO NOT store flammable materials near this heater.
The filter meshing for this appliance is fixed to the inlets of the room
air return .
The build up of dust or other particles on these filter strips reduces the
air flow through to the heater which in turn reduces heater's efficiency
and can lead to the appliance shutting down.
Filter Care
Filters require cleaning regularly during the heating season to prevent
these unnecessary cut-outs.
Cleaning filter strips:
Clean any dust and other debris from both faces of the filters with
either a vacuum cleaner, a soft dry cloth or a soft brush. NEVER
attempt to clean filters with water.
Heater shut down due to filter blockages
DO NOT wait for the Filter Blockage Indicator to come on before
cleaning filters.
DO NOT continue to use the heater once this Indicator is flashing.
When an obstructive build up is detected the Blockage Indicator LED
which is located above the Receiver Window will begin to flash
RED to let you know that there is a problem.
Once the Indicator is flashing if no action is taken the heater will
eventually shut down to avoid overheating and a fault code of 14 will
be displayed in the Error Display window.
Returning the appliance to normal operation after a shut down
To restore to normal operation after a filter blockage shut down do the
following:
1. Access the 'Push Button Control Panel' . This is located on
the front of the heater at the lower right hand corner.
2. Press the On/Off button once to turn off the heater.
3. Remove obstruction (see “Filter Care” on page 13).
4. Press the On/Off button once to turn the heater back on.
5. Use the remote control to resume normal heater operation.

CARE AND MAINTENANCE
GENERAL HEATER CHARACTERISTICS
SERVICE
Rinnai recommend that this appliance and installation be inspected and serviced every 2 years.
If the power supply cord or any other component of the heater are damaged, they must be replaced by Rinnai or
a suitably qualified person.
Any service or repair work should only be carried out by an authorised person. Rinnai has service and spare parts
departments nationally, see back cover for contact details.
TROUBLE SHOOTING CHECKLIST
Use the following chart to help determine whether a service call is required, however if you are unsure about the
way your heater is operating, contact Rinnai or your local agent.
ABNORMAL FLAME PATTERN
Each Rinnai Gas Fire has a distinct flame pattern. The flame should look the same every time you start your heater
after an initial warm up period of approximately 15 minutes.
Before asking for a service call please check the following table as these characteristics are part of the normal
operation of the appliance and do not indicate a fault.
CHARACTERISTIC EXPLANATION
At ignition:
Warm air does not start when the burner lights. The room air fan is started automatically after a short
delay. This is to allow the heat exchanger to warm up,
helping to avoid cold draughts.
Smoke or strange smells are produced on the first
start up operation after installation. This is caused by grease, oil or dust on the heat
exchanger when new. This will stop after a short time.
Sharp clicking sparking noises at ignition. This is the electronic ignition sparking.
Ticking or pings when the unit thermostat modulates
to a lower or higher setting, or shuts down. This is simply expansion and contraction noise from
the heat exchanger and is normal.
During combustion:
Clunking noise when the thermostat operates This is the sound of the solenoid gas valves opening
and closing to regulate the gas flow and is normal.
When the appliance is turned off:
Convection fan continues to run after turning off. This is to remove residual heat from the heat
exchanger and stops once the appliance cools.
Other points:
Steam is discharging from the flue terminal. High efficiency appliances tend to discharge water
vapour on cold days. This is normal.
Heater does not start when the STANDBY / ON
button is pushed, thermostat is on High (H). Check that the appliance ON/OFF button is ON.
Service calls for general cleaning, maintenance and wear and tear are not necessarily covered
under the warranty. Service calls of this nature may be chargeable.
Faults caused by insufficient gas supply, gas quality, installation errors or operation errors are not
covered by the Rinnai warranty. Refer to separate warranty booklet.
Appliances incorporating a live fuel effect and designed to operate with luminous flames may
exhibit slight carbon deposition on burner media. Slight deposition is acceptable.
NOTE

Rinnai 15 RHFE 952_1252 OIM
CARE AND MAINTENANCE
Abnormalflameperformance and/or pattern can indicate a problem with your heater,such as blockedgas injectors,
incorrectly installed / inadequate flue system or the Ceramic logs / stones and or burner media may have shifted
from when the heater was first installed.
There are some warning signs that could indicate a problem. If any of the signs below occur, please contact Rinnai.
Key signs of Abnormal flame performance:
• Appliance turns ‘OFF’ soon after start up and does not relight.
• Flame appears overly orange-yellow.
• Flame appears either very short or very long.
• Flame only burns part way across the burner.
• Severe soot building up on the inside of the glass and logs.

HEATER LOCATION
When positioning the heater the main variables governing the location are Flueing and Warm Air Distribution.
This heater must not be installed where curtains or other combustible materials could come into contact with it. In
some cases curtains may need restraining.
ENCLOSURE REQUIREMENTS
These Rinnai units have a cool outer casing allowing it to be installed into existing Masonry fireplace or into a
decorative fireplace constructed from combustible materials such as wood or plaster.
A pair of wheels located at the rear the heater
allows it to slide in and out of the enclosure for ease
of commissioning and maintenance. As such the
heater must be positioned on a flat and level
surface that allows free movement.
In a masonry fireplace, use a slurry of sand and
cement to level the base as required.
In a decorative fireplace, if the appliance is
elevated from the ground, a base must be
constructed using a board with supporting joists as
shown. The joists used to support the appliance off
the ground MUST BE capable of supporting a
minimum of 105 kg.
WALL PENETRATION REQUIREMENTS
Mark the location of the gas supply (consumer piping) and flue pipe
penetrations from the centreline of the heater enclosure using the
following dimensions:
Consideration must be given to the position of any studs, noggins or other
components of the wall structure.
For all installations, ONLY Rinnai ASP & ES Flue components MUST BE used. The Rinnai RHFE-
952ER & RHFE-1252ER units MUST NOT be flued into ‘natural draft’ flue system or via a chimney.
Consult the Rinnai “Power Flued Flamefire Space Heater Co-axial Flue System Installation Manual”
supplied with flue kits ASPDFK or ASPKIT03 for detailed flue installation instructions.

The enclosure dimensions specified are critical to the
successful installation of this appliance and must be strictly
adhered to.

500 mm from base of enclosure plus or minus 25mm
Ensure the penetration points are marked accurately as this is critical for successful appliance
installation.
The penetration for the flue pipe only needs to be made for ‘Direct’ flue installations, where the flue
terminal is located directly to the rear of the appliance.
If no flue pipe penetration is required the markings are still useful for indicating the correct
position of the flue transition within the enclosure for extended horizontal flue applications.

GAS SUPPLY
ELECTRICAL SUPPLY
MANTLE INSTALLATIONS
The gas supply terminates inside the heater and enters the appliance
from the rear. To ensure correct positioning, terminate the gas supply
so that it is 125 mm from the front of the enclosure opening.
Fit the supplied adapter and flexible hose to the gas supply prior to
moving the heater into the enclosure.
Gas pipe sizing must consider the gas input to this
appliance as well as all other gas appliances in the
premises. The gas meter and regulator must be
specified for the total gas rate. Suitable sizing chart
such as the one in AS/NZS 5601 should be used.
PURGING THE GAS SUPPLY: All foreign materials such
as filings must be purged from the gas supply, as they
may cause the gas control valve to malfunction.
This heater has a power cord with a three pin plug supplied. The
power cord passes through the gap at the rear left of the appliance.
Rinnai recommend the heater be plugged into a 230V, 10A earthed
power point. The power point must be a maximum of 1500 mm to the
side of the heater (it must not be above the heater). Alternatively the
appliance can be direct wired if the power supply is to be concealed.
Consult a qualified electrician if direct wiring is required
as it must comply with the requirements of AS/NZS 5601
and AS/NZS 3000 and any other relevant local
regulations.
A mantle is permitted providing the following clearances are met.
* 75 mm is the minimum clearance required for access to the heater controls and to allow cleaning
/ servicing.
