when cooled down.
Electrical Fuse: The electrical circuits are protected by a fuse.
Flame Failure Sensing System: Automatically cuts o󰀨 the gas supply to the heater in the event of a ame failure.
Power Failure: In the event of a power failure while the heater is in operation the fan will stop, however the gas
valves remain open and continue to heat the appliance. The overheat protection may then shut o󰀨 the gas to

GENERAL DESCRIPTION
Your Slimre is a burning log e󰀨ect, gas space heating appliance with natural draft combustion system, intended
for use with Natural Gas and Propane. The burning log e󰀨ect is achieved using two main burners with strategically
placed, 'life like', imitation logs and granules. Temperature control is achieved through manual push button control.
This heater has an electronic ignition. The pilot is only on when the heater is in operation.
Burner, logs and granules are contained in a glass fronted, sealed burner box.
Combustion air is drawn from the room. Combustion product is exhausted via the ue discharge vent when installed
in a masonry chimney or when installed in a zero clearance box through a 100mmØ x 150mmØ twin skinned ue
to the outside of the house.
Fireplace / Masonry installation - Engine:
The appliance is directly mounted into an existing masonry re place or a non-combustible/masonry enclosure that
has a chimney. When installed correctly the appliance is a ush to wall mount.
Zero Clearance installation:
The appliance is tted within a sheet metal Zero Clearance Box Assembly that has been installed into a wall or
other suitable structure. Materials need not be non-combustible. When installed correctly the appliance is a ush
to wall mount.

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. Refer to
"Operational Safety Warnings" on page 6 for additional
safety considerations.
IMPORTANT
Horizontal and vertical clearances are
measured from the edge of the burner box
glass.
Mantles and surrounds can be added to compliment
the design provided that they conform to the following
clearances requirements.
The minimum clearance from the edge of the burner box
glass is 300 mm. The depth of the mantle or surround (A)
at this minimum clearance may not exceed 150 mm.
An additional 100 mm of clearance is required for every
extra 50 mm of mantle depth. The depth of the mantle
or surround (B) at 400 mm of clearance may not exceed
200 mm.
Ensure that the area in which the appliance is installed has
adequate xed ventilation, this xed ventilation must be
provided as detailed in AS/NZS 5601.1.

Refer to the table below and the dimensional drawings on this page and on
page 16 for appliance gas inlet location and other relevant dimensions.
1. Mark o󰀨 the location for the vertical centre line (1) of the heater enclosure.
2. To the right of the vertical centre line (1), mark o󰀨 both the vertical (2) and
horizontal (3) location for the gas supply penetration (consumer piping).
For measurements refer to the Gas Supply Dimension Table below.
CAUTION
The length of the gas supply (consumer piping) termination
(4) is measured from the front of the enclosure including the
thickness of any cladding material.
Gas Supply Dimension Table
2280mm to right of appliance centre-line (1)
343mm from base of enclosure
4Consumer piping to be terminated 79mm from the front of enclosure
Purging Gas Supply
Foreign materials and debris such as swarf, lings, etc. MUST be purged / removed from the gas supply, failure
to do so may cause damage to the gas control valve causing it to malfunction.
Leak Testing the Connection
Plug the end of the consumer piping gas and leak test all joints.
CAUTION
Use a soapy solution to test all gas connections. If a leak is present bubbles will form at the leak
point. When nished remove any residue with a rag. Prevent any soapy solution from coming in
contact with electrical components.
ELECTRICAL SUPPLY
If a power point is used it MUST be 230 V, rated at 10A and MUST be earthed.
This power point MUST NOT be located above the heater. The heater engine
is tted with a 1.5 metre power cord and three pin plug which can exit the
appliance from either the lower left or right hand side of the heater as required.
Direct Wired Installations
Alternatively the appliance can be direct wired to conceal the power supply.
IMPORTANT
A qualied electrician will need to be consulted where a direct wired installation is required. Any
such installation must comply with the requirements of AS/NZS 5601, AS/NZS 3000 and any other
relevant local regulations.

FLUE INSTALLATION OPTIONS
WARNING
The following diagrams illustrate the ue installation options that are available for the Slimre
252 ame. ONLY the genuine Rinnai Flamere (FLF) ue is certied as part of the Rinnai Slimre
252 space heaters.
ONLY an authorised person must install, service and remove the Rinnai Slimre 252 space
heater and ue system.
ONLY the ue system components described in the ‘Flueing Installation Manual For Rinnai
Flamere Heaters’ that is provided with the ue kit must be used.
Components that are not described in that manual, whether manufactured by Rinnai or otherwise,
are NOT compatible and must not be used.

IMPORTANT
Read this manual thoroughly and gain a full understanding of the requirements before undertaking
installation.
Step 1. Prepare Site
IMPORTANT
Ensure the intended enclosure meets the requirements of the dimensions as stipulated in
"Enclosure Requirements" on page 15 and that gas and electrical supplies have been prepared
in accordance with the dimensions stipulated in "Gas Supply" on page 16 and "Electrical
Supply" on page 16.
Carefully remove the foam packaging from the outside top of the heater engine, as this packaging
contains the fragile burner media it will need to be placed safely aside until required.
Step 2. Unpack The Heater Engine
The heater engine is supplied in one carton, check to ensure you have all contents as listed on "Carton Contents
/ Item Checklist" on page 8 at the start of this manual before proceeding.
Carefully remove carton by removing the straps and lifting the carton o󰀨 the appliance. Remove all packaging
materials and check all components for damage. If ANY damage is evident DO NOT install or operate this
appliance. Contact your supplier for advice.
IDEA
Retain the cardboard carton for use in the "Step 4. Positioning the Heater Engine".
Before installing the heater, check it is the correct gas type, (refer to the gas type label on the top body panel of the
heater). Refer to the local gas authority for conrmation of gas type if you are in doubt.
Step 3. Preparing Heater Engine
Attach the adhesive backed foam sealing strip (A) supplied to rear face of the fascia assembly mounting panel (B).
Ensure the seal is stuck to the Fascia Assembly mounting panel at approximately 20mm from the top edge (C).
The foam strip is intended to form a seal between the heater and the replace brickwork. If an adequate seal
cannot be formed then another means of sealing must then be used. (e.g. non combustible insulation or heat
resistant silicon).
Remove (do not discard) the gas/electrical access plate (D) ve screws.

Step 4. Positioning the Heater Engine
