Overview

Function Description
Usage Features
Maintenance Features
Installation Instructions (for authorized personnel)

The Rinnai Flame Fire ETR is an electronic timer and remote-controlled gas heater designed for in-built radiant/convector heating with a glass front and ceramic logs. It utilizes a forced convection and natural draught flue system, making it suitable for integration into existing fireplaces. This manual provides comprehensive instructions for both customer operation and professional installation, ensuring safe and efficient use of the appliance.

Function Description:

The Rinnai Flame Fire ETR serves as a primary heating source, offering both radiant and convective heat to warm a room. Its core functionality revolves around a gas burner that ignites ceramic logs, creating a visual flame effect similar to a traditional wood fire. A forced convection fan then distributes the generated heat throughout the space. The appliance is equipped with an electronic control system that allows for precise temperature management, timed operation, and remote control for user convenience. Safety features are integrated to monitor operation and prevent potential hazards.

Usage Features:

The Rinnai Flame Fire ETR offers a range of user-friendly features designed to enhance comfort and control:

Control Panel Layout: The appliance features an intuitive control panel with clearly labeled buttons and a digital display. Key controls include:
- LOCK Button: Activates a lock function to prevent accidental operation, particularly useful in households with small children. To activate, press the button once; to deactivate, press and hold for 3 seconds.
- Flame Function: Engages a default Medium High heat setting to maximize the visual flame effect, overriding the thermostat for aesthetic preference.
- TIME/TEMP. Display: Shows the current time of day, set temperatures, or coded error messages, providing essential operational feedback.
- CLOCK ADJUSTMENT AND TIMER INDICATORS: These indicators illuminate when the clock or dual timer program is being set, guiding the user through the setup process.
- Set Times Button: Used to access and adjust clock and timer settings.
- Override Button: Temporarily changes the heater's operation from ON to OFF or OFF to ON, allowing for immediate adjustments outside of programmed settings. The override remains active until pressed again or a programmed timer setting is reached.
- Timer 1 and Timer 2 Buttons: Selects either of the two programmable timers for automated operation.
- Temp/Time Adjustment Buttons (Up/Down Arrows): Used to increase or decrease temperature settings and adjust hours or minutes during clock and timer setup.
- AUTO OFF Button: When ON, the thermostat reduces heat to the OFF setting. When OFF, the thermostat reduces heat to the LOW setting.
- ON/OFF Button: The main switch to turn the appliance ON or OFF.
Turning On/Off: To turn on, press the ON/OFF button. A green indicator will glow, followed by the spark generator sound. Once ignited, the indicator turns red. The convection fan activates automatically after 4 minutes. To turn off, press the ON/OFF button again; the indicator will go out, and the fan will continue to run for several minutes to cool the appliance. It is crucial not to unplug the appliance to turn it off, as the fan needs to complete its cooling cycle.
Room Temperature Adjustment: While the heater is running, users can adjust the room temperature using the Temp/Time Adjustment buttons. Temperatures can be preset to Low (approx. 10°C), 16°C to 26°C in 1°C steps, or High (continuously high). The ON indicator changes from red to green when the preset temperature is reached, and the heater stops running.
Setting the Clock: After initial plug-in or a power failure, the digital display will show "--:--". To set the clock, press the SET TIMES button once, then use the Temp/Time Adjustment buttons to set the desired time. Pressing the SET TIMES button five times locks in the setting.
Programming ON/OFF Timers: The appliance supports two programmable timers for automated heating periods. Before programming, ensure the clock is set correctly. To program, press the Set Times button twice (for Timer 1) or three times (for Timer 2), then use the Temp/Time Adjustment buttons to set the ON and OFF times. Pressing the Set Times button three times (for Timer 1) or five times (for Timer 2) locks in the program. Programmed times must be selected and locked-in within one minute to be retained.
Operating the Timers (Set and Forget): To activate a timer, press the corresponding Timer 1 or Timer 2 button after turning the heater ON and selecting the desired temperature. The timer indicator will glow, and the heater will remain in standby until one hour before the programmed start time, at which point it will flash and begin preheating the room. Both timers can be selected for alternating operation during cold weather.
Preheat Function: This automatic function operates in conjunction with the timers. When a timer is selected, the heater may begin operating up to an hour before the programmed ON time to preheat the room, based on the sensed temperature differential.
Remote Control: A handheld remote control provides convenient operation from a distance. It includes ON/OFF buttons and Temp/Time Adjustment buttons to alter the temperature. The remote operates within 5 meters and a 40° angle to the receiver on the heater. Note that the remote will not turn the heater ON if timers are selected. Pressing the OFF button on the remote while timers are active and the heater is in standby will deactivate the timers.

Maintenance Features:

Proper maintenance ensures the longevity and optimal performance of the Rinnai Flame Fire ETR.

Cleaning Instructions:
- Before cleaning, ensure the power and gas are turned off, and the heater has cooled down completely.
- Do not remove any internal wiring covers.
- Use only non-abrasive and non-solvent-based cleaners.
- Outer Case: Clean with a soft, damp cloth. Avoid aerosol polishes while the heater is in operation.
- Glass Cleaning: The glass panel may require cleaning after a period of use. The manual provides instructions for removing side panels and glass for cleaning purposes. This involves opening side panels, removing fastenings for the top glass retainer, lifting the retainer, loosening screws on the bottom glass retainer, and carefully lifting out the glass.
Log Installation/Removal: The manual details the correct procedure for installing the ceramic logset, which is packed inside the heater for shipping. This involves opening side panels, removing glass retainers and glass, positioning the Main Log onto locating pins, and then placing the Top and Right Logs onto the Main Log's pins. Loose ember bed material should be gently placed in front of the front log, avoiding burner ports. If logs need to be removed for cleaning or service, the ember bed material should be removed first and replaced last.
Battery Replacement (Remote Control): The remote control uses a CR2032 Lithium battery. To replace, simply open the back of the remote control. Remove the battery if the control will not be used for an extended period to prevent damage from leaking batteries.
Troubleshooting: The manual includes a comprehensive troubleshooting guide with common symptoms, probable causes, and solutions. This allows users to address minor issues themselves before contacting service. Examples include:
- Burner will not light: Check power, gas supply, purge air (installer), or repeat lighting procedure.
- Smell of gas: Turn off gas at the meter and call an installer immediately.
- Fan not working: Ensure the heat switch is activated and the appliance fan switch is ON.
- Severe soot deposit: Call Rinnai Service Dept./Agent, as this may indicate an inadequate flue system, log misalignment, or incorrect gas pressure.
- Digital Error Message on Control Panel: Refer to the "Error Codes" section for specific fault codes (e.g., 11 for Ignition Failure, 14 for Overheat, 73 for Communication error) and suggested actions, which often involve turning the heater OFF and then ON again.
Error Codes: The appliance continuously monitors its operation and displays error codes on the digital display if a fault occurs. These codes assist in diagnosing problems and often suggest initial user actions. If an error persists, users are advised to contact service and quote the displayed code.
