Rinnai LS (V2) Gas Fireplace Installation Manual

Location

Main variables governing 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. Refer to "General Safety Warnings" on page 6 for additional safety considerations.

Horizontal and vertical clearances are measured from the edge of the burner box glass.

Combustible mantles and surrounds can be added provided they conform to clearance requirements. The minimum clearance from the edge of the burner box glass is 400 mm. The depth of the mantle or surround (A) at this minimum clearance may not exceed 250 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 500 mm of clearance may not exceed 300 mm.

Refer to "Wall Lining Installation" (page 28) for additional information and "Cavity Ventilation" (page 9) for cavity ventilation details.

Combustion product spillage testing must be conducted during commissioning. This testing may show a need for additional fixed ventilation.

Diagram Description (Fig. 1): Shows clearances around the fireplace. Minimum 400mm side and top clearance from glass edge. Minimum 1000mm front clearance from dress guard. Mantle depth limits are shown: A=250mm at 400mm clearance, B=300mm at 500mm clearance.

TV & Ornamentation Warning

INSTALLATION OF TV OR ORNAMENTATION ABOVE THE HEATER:

Electrical appliances and ornaments installed above and in the vicinity of the heater must comply with their manufacturers' instructions. It is the installer/end-user's responsibility to check these instructions and ensure the location is suitable. This includes items like Plasma TVs, LCD TVs, Home Theatre Screens, Speakers, Paintings, Prints, Photographs, Tapestries, Mirrors, Stuffed Animals, etc.

Note the recommended clearances as per the diagram above. The wall surface directly above the appliance may be elevated in temperature and may discolour paint finishes or distort vinyl wall coverings. Contact the relevant manufacturer for their specifications for surface durability.

RINNAI DOES NOT TAKE ANY RESPONSIBILITY FOR ANY DAMAGE OCCURRING TO ANY ITEMS INSTALLED ABOVE AND IN THE VICINITY OF THE HEATER.

Use either a shelf or mantle below the TV or ornament, or construct a recess to mount them. Check manufacturers' installation instructions for these items and ensure the recess is suitable.

Base Board and Cut-outs

To ensure proper alignment, pencil the following on the base: glass centreline, unit depth centreline, feet position, gas and room thermistor cut-outs.

*Assumes 10mm plasterboard / All dimensions in mm

Cavity Ventilation

Ventilation areas of at least 2000 mm² each are required in the cavity, ideally at the bottom and top ends of the appliance. This allows room air to enter at the bottom and exit at the top, reducing heat buildup and increasing efficiency. Ventilation can be via manufactured vents or a sized opening/gap.

When installing materials susceptible to heat damage (like wood) directly above the appliance, allow a sufficient air gap and fit non-combustible material underneath. All specified clearances must be provided.

Additional Framing Notes

• Plasterboard is set 1 mm back from the front edge of the frame for a slim edge plaster finish.
• The appliance MUST be installed on a flat, level support base for correct and rattle-free performance. Issues caused by rattling fires not installed on a flat level base will NOT be covered by warranty.

Installing Engine Into Cavity

Using the handholds and carry bars, carefully lift and slide the heater engine into the enclosure and position it. Ensure the unit is level using the adjustable feet on all corners. This is critical for wall lining installation.

Seismic Brackets: In areas with seismic activity, secure the heater engine to the bottom of the cavity using the four seismic brackets. These brackets need to be elevated before unit installation to allow for leveling.

Removing the Burner Box Glass

The glass front is held by retainer latches at the top. Take care when lifting the glass, as the RHFE1500 glass weighs approximately 7 kg.

Removal Procedure:

1. Loosen screws holding the louvre, remove the louvre, then remove the screws holding the glass.
2. Push the top glass retainer latches up and slightly to one side to release the top section of the glass.
3. Using the frame tabs at the top of the glass frame, lift up, gently slide to the right, and rotate the glass until the left section comes free. Move the glass panel to the left to remove the right section.

Diagram Description: Illustrates how to release the glass retainer latch by pushing it up and to the side. Shows glass front tabs for lifting.

Gas Supply

Gas pipe sizing must consider the total gas input for all appliances. The gas meter and regulator must be specified for the total gas rate. Use a suitable sizing chart (e.g., AS/NZS 5601). The use of rubber hose for gas connection to a fixed appliance is NOT authorised.

Confirm correct gas type (see labels on top/rear panels). Refer to local gas authority if in doubt.

Room Thermistor

Once installed, the room temperature thermistor should be positioned so its bulb is outside the firebox and in an area where room air will be drawn over it from the lower room ventilation.

The thermistor has a 1.5-meter lead and should be positioned in the airflow of the cavity ventilation. It may be mounted directly to the inside of an air vent grill. The thermistor MUST be accessible for servicing after wall linings are installed.

Diagram Description: Shows the thermistor bulb positioned to receive airflow from the lower room ventilation.

Electrical Supply

This heater has a 1.5 m power cord with a three-pin plug. The cord exits through a slot on the front right-hand side, approximately 150 mm from the front.

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. A switch must be provided to electrically isolate the appliance for servicing.

Direct Wired Installations: The appliance can be direct wired. A qualified electrician must be consulted. A switch is required for isolation. Any such installation must comply with AS/NZS 5601, AS/NZS 3000, and relevant local regulations.

Flue Exhaust & Air Inlet Connections

These connections are critical. If not secured correctly, products of combustion could disperse into the room.

Steps:

1. Connect the flue terminal exhaust connection to the flue exhaust outlet and secure with the flue locking bracket.
2. Secure the flue transition to the framing using a wall clip.
3. Attach the air intake hose to the large air inlet connection on the flue transition and secure with a cable tie. The other end of the air inlet hose is pre-installed to the appliance.
4. Ensure the rubber cap remains secured on the unused (small) air inlet connection.

Gas Pressure Setting

Gas supply and burner pressures MUST be checked during installation and prior to installing burn media. This is done with the glass off and before burn media is added. Make adjustments only if the unit is not operating correctly after all other causes have been eliminated.

Inlet supply pressure MUST be checked and set within the appliance's operating parameters. If the appliance cannot be adjusted correctly, contact Rinnai.

Confirm gas type (Natural or Propane). Contact local gas authority if in doubt.

* For heaters with Flametech burner media (RHFE0800SF/DF), the two large logs are the main burners and must be temporarily installed onto aeration sleeves during commissioning.

Pressures can be checked and adjusted via buttons on the control panel PCB through front access panels or by pulling out the PCB.

Check pressures against the data plate. If the data plate is not accessible, pressures are detailed on the next page. Access to the 'SET' button may be required even if no adjustment is needed.

Commissioning the PCB

PCB commissioning steps are ONLY to be done if the PCB is being replaced or after a gas conversion.

1. Turn on gas and power supply.
2. Press the 'Test' button. The display shows the gas code (A1 = Natural, L1 = Propane). Use 'Up' and 'Down' buttons to select the correct code, then press 'Set' to lock it in.

PCB commissioning is now complete; gas pressures can be checked.

Gas Control Solenoids

Diagram Description: Shows the gas control unit for RHFE0800F/1000 with test points and adjustment screws for inlet pressure, pilot pressure, and main burner pressure. The RHFE1500 has an additional solenoid.

Gas Pressures

Tables provide gas pressure specifications for RHFE0800SF/DF, RHFE1500S/D, and RHFE1000S/D models, detailing settings for Natural Gas and Propane, Short Flue (S-F) and Long Flue (L-F) configurations. Specifications include gas rate (Hi/Lo), injector sizes, pilot pressure, and main burner pressures (PL, PH, PF, PA).

Key: S-F = Short Flue Setting, L-F = Long Flue Setting, LH = Left Hand, RH = Right Hand, PL = Main burner on Low, PF = Main burner on High, PA = All burners on Low, PH = All burners on High.

Burn Media Installation

Due to the number of steps, separate instructions and a colour placement sheet are supplied with each burn media type. Correct placement is critical, as incorrect installation is a common cause of performance problems and can create carbon build-up, affecting heater performance. Malfunctions due to incorrect burn media placement are NOT covered by warranty.

The appliance MUST NEVER be used with other or damaged burn media. Burn media sets are different and cannot be interchanged.

Test Operation and Lighting Sequence

It may take approximately two hours of operation for the burn media to achieve their full flame pattern and glow. Some smoke and smell may be experienced during the initial burning-in period; run the appliance on high in a well-ventilated room until these dissipate. Check flame pattern during this time.

Check Wi-Fi Connectivity

Test Wi-Fi connectivity and operation with the owner/customer. When power is on, the Wi-Fi LED should flash then turn solid red, indicating readiness for smart device setup. The app links the fire's Wi-Fi to the smart device and then to the home Wi-Fi router, making the smart device the controller.

Installation Checklist & Installation Record

It is the installer's responsibility to complete both the "Installation Checklist" and the "Installation Record" on pages 16 and 17 of the operation manual at the completion of installation.

Plasterboard Wall With Plastered Finish

This method applies when the wall is flush with the front of the heater only. Any wall linings extending beyond the fire front MUST be rated non-combustible.

Adhesive is recommended. Wallboard Support MUST be used for combustible wallboard and is designed for thicknesses of 10, 13, and 20 mm, allowing for a 1 mm setback for the Finishing Trim or plaster finish.

Diagram Description: Illustrates the plasterboard installation with Wallboard Support. Shows different tab settings for 10mm, 13mm, and 20mm boards. Notes explain trimming tabs and options for using or removing Finishing Trim latches.

Edge Finishing Options

Applicable to any installation method. Rinnai optional Finishing Trim is suitable where wall lining is at least 1mm set back from the fire's front face. Adhesive is recommended over screws for permanent fixing across the top of the fire.

Diagram Description: Shows three edge finishing options:

1. With optional Rinnai Finishing Trim (requires 1mm setback).
2. With wallboard edge finish (no plaster or trim finish), noting potential visibility of Wallboard Support panel and trim clips.
3. With rebated wallboard edge finish, providing a closer fit but making the front edge vulnerable to damage.

All options require a minimum 3mm air gap.

Tiled Or Second Skin Wall Linings

Wall linings less than 20 mm may be combustible if the wallboard support is installed. Mechanical fixings are not recommended across the top of the fire; adhesive is best. With Wallboard Support removed, the wall lining must be non-combustible for at least 300 mm up the wall.

Diagram Description: Shows tiled/second skin installation. Notes emphasize non-combustible backing below timber lintel line if Wallboard Support is removed. Minimum 3mm air gap and 50mm clearance from top of heater engine to combustible materials are required.

Non-Combustible Thick Wall Linings

With Wallboard Support removed or wall lining protruding beyond the fire front, the wall lining must be non-combustible for at least 300 mm up the wall.

Diagram Description: Illustrates non-combustible thick wall lining installation. Emphasizes non-combustible material requirements, clearance around glass trim latches, and options for Finishing Trim or panel edge finish.

Non-Combustible Recess Installations

Diagram Description: Shows non-combustible recess installations. Key features include a 45° non-combustible lintel, minimum 3mm air gap, and 50mm clearance from the top of the heater engine. Materials within specified areas must be non-combustible. Walls must not protrude beyond the front boundary line. Finishing options include high-temperature rated finishes or panel edge finishes.
