The Rinnai Neo is a gas fireplace designed for both inbuilt and freestanding installations, offering a modern aesthetic combined with advanced technology. It operates as a burning log effect gas fire with a natural draft combustion system, suitable for use with Natural Gas (NG) and Universal Liquefied Petroleum Gas (ULPG). The appliance features an electronic ignition with an intermittent pilot, meaning the pilot flame is only active when the heater is in operation.
Function Description:
The primary function of the Rinnai Neo is to provide heat to large areas, with a heat output of up to 6.94 kW. It achieves this through a convection fan that helps circulate warm air efficiently throughout the room. The appliance is designed to be modular, consisting of an 'engine' that can be configured in three types:
- Masonry Installation: Directly mounted into an existing masonry fireplace or a non-combustible masonry enclosure with a chimney.
- Zero Clearance (Mock Chimney) Installation: Fitted within a zero clearance box and then inserted into a wall or other suitable structure.
- Freestanding Installation: Housed in a decorative fabricated sheet metal box, designed to be freestanding rather than inbuilt.
Air for combustion is drawn from the room, and by-products are exhausted via a flue discharge vent to the outside.
Usage Features:
The Rinnai Neo offers flexible control options, primarily through an intelligent electronic timer remote (ETR) wireless controller, but also via a manual control panel on the appliance itself.
Wireless Controller:
The wireless controller acts as a thermostat, sensing room temperature and communicating with the Neo via radio frequency. It should be wall-mounted within 10 meters of the fire, ideally 1.5 meters from the floor, away from drafts and direct sunlight, and 2-10 meters from the heater.
- Child Lock Function: To turn the controller on, both the PWR and OK buttons must be pressed simultaneously. Pressing PWR alone switches the controller off. This function cannot be overridden.
- Modes of Operation: The Neo has three modes:
- Manual Mode: Allows the user to set a desired temperature. The heater will adjust its heat output to maintain this temperature. Time and day settings are not required in this mode.
- Auto Mode: Operates based on programmed timers and temperatures. The heater monitors room temperature and adjusts its output to maintain a comfortable heat. If the set temperature is reached, the fire will turn off and restart when the temperature drops.
- Flame Mode: Allows the user to set a preferred flame setting (F1-F7, F7 being highest) regardless of room temperature. In this mode, the heater will not automatically turn off unless the room temperature exceeds 40 °C (a safety feature).
- Programming: The controller can be programmed for four periods each day of the week, allowing for specific start times and temperatures.
- Temperature Control: Temperature can be adjusted using UP and DOWN buttons, with a range of 7-32 °C. A "-- °C" setting indicates no set temperature, keeping the fire off until the next programmed setting.
- °C/°F Display: The thermostat display can be switched between Celsius and Fahrenheit.
- Synchronisation: If the controller is not synchronised or is purchased separately, a specific sequence of steps involving powering off/on the appliance and pressing controller buttons is required to establish communication.
- Battery Indicator: A symbol flashes when batteries need replacing, providing approximately five days of functionality before shutdown.
Operation Without the Controller (Manual Control Panel):
If the wireless controller is lost or its batteries are flat, the unit can still be operated using the control panel on the appliance.
- Turning On: Press the ON/OFF button once. The electronic ignition sparker will activate, establishing the pilot flame, followed by the main burner igniting at the highest setting. A blue LED power indicator will stay on.
- Flame Height Adjustment: After one minute of operation, the UP and DOWN arrows can be used to increase or decrease the flame height (seven settings). Fan speed is preset and linked to flame height.
- Turning Off: Press the ON/OFF button once. The blue LED indicator will turn off.
Safety Features:
- Overheat Switches: Automatically turn off the gas if the heater gets too hot (e.g., if air outlet louvres are blocked). The heater will only restart once it has cooled down.
- Electrical Fuse: Protects the electrical circuits.
- Flame Failure Sensing System: Automatically cuts off the gas supply if the heater fails to ignite after several attempts, preventing gas build-up.
- Power Failure: Gas valves automatically close, and the unit shuts down during a power cut.
- Glass Dress Guard: Must be fitted to reduce the risk of serious burns and should not be permanently removed.
- Automatic Shut Off (Over Temperature): If room temperature exceeds 40 °C for more than three minutes, the controller will automatically shut down the heater.
Maintenance Features:
- Cleaning: External surfaces can be cleaned with a soft damp cloth and mild detergent. Solvents should not be used, and the heater should not be cleaned while hot or operating.
- Servicing: For reliable operation, Rinnai gas fireplaces, including flue system inspection, should be serviced every two years. More frequent servicing may be beneficial in dusty environments or if subject to excess lint.
- Soot Deposits: Small soot deposits on logs or glass are normal. Significant build-up requires a service call.
- Abnormal Flame Pattern: Users are advised to contact Rinnai if they observe unusual smells, difficulty establishing a flame, very short or long flames, partial burning across the burner, or severe soot build-up on the glass, as these may indicate a problem.
