Consumer Safety Information Safety Definitions This is the safety alert symbol. This symbol alerts you to potential hazards that can kill or hurt you and others. DANGER Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
Description of Operation The Rinnai water heater is one of the most advanced water heaters available. It provides a continuous supply of hot water at a preset temperature. This appliance is direct vent where air is brought in from the outside and combustion gases are exhausted to the outside. While electricity, water, and gas supplies are connected, the Rinnai water heater produces hot water whenever a hot water tap is open. Installation of the remote controller is highly recommended.
Remote Controllers - Models MC-91-1US & MCC-91-1US Dimensions (inches): 3.5 W x 4.75 H x 0.75 D The MC-91 controller allows a maximum temperature setting of 140º F. The MCC-91 controller is for commercial and hydronic applications requiring higher temperatures. When the MCC-91 controller is connected, these higher temperatures are available on all controller models in the system. Refer to the section on temperature ranges.
Remote Controllers - Models BC-100V-1US Dimensions (inches): 8.0 W x 4.125 H x 0.875 D NOTICE The BC-100V controller is water resistant. Avoid splashing the controller. In Use Indicator Temperature Display Water Smart Bath Fill Indicator ON/OFF Button Priority Button and Indicator Water Smart Bath Fill Button Call Power Save Clock Water Volume Thermostat Sound Volume MC-100V-1US Dimensions (inches): 5.0 W x 4.75 H x 0.
Setting the Temperature DANGER Hot water can be dangerous, especially for infants or children, the elderly, or infirm. There is hot water scald potential if the thermostat is set too high. Water temperatures over 125º F (51º C) can cause severe burns or scalding resulting in death.
Temperature Ranges This water heater will attempt to provide hot water at the temperature even when the water flow is varied or when more than 1 tap is in use. The water heater can deliver water at only one temperature setting at a time. The available temperatures for a given model are provided below.
Using the Water Smart / Bath Fill Function Overview This function is exclusive to the BC-100V remote controller. The bath fill function allows the consumer to fill a tub with a preset volume of water at a preset temperature. This is done by pressing the bath fill button on the BC-100V controller while no hot water is flowing and then opening only the hot water tap. The water heater will cease the hot water flow when the preset volume has been reached.
Using the Water Smart / Bath Fill Function Filling the Tub 1. Press the “Water Smart / Bath Fill” button once. The button will illuminate, a tone will sound, and the word “Bath” will appear next to the temperature setting. ON! COLD HOT ON! HOT COLD 2. The voice prompt will announce “The hot water system is ready. Open the hot water tap.” Open the hot water tap. The “In Use” indicator will illuminate on all controllers. The hot water will begin to flow. 3.
Maintenance Snow Accumulation WARNING Turn off the electrical power supply, the manual gas valve and the manual water control valve whenever servicing the unit. Repairs should be performed by a qualified service technician. The appliance should be inspected annually by a qualified service technician. Verify proper operation after servicing. Cleaning It is imperative that control compartments, burners, and circulating air passage ways of the appliance be kept clean.
Error Codes The Rinnai water heater has the ability to check its own operation continuously. If a fault occurs, an error code will flash on the Display of the remote controller. This assists with diagnosing the fault, and may enable you to overcome a problem without a service call. Please identify the code displayed when inquiring about service. WARNING Some of the checks below may need to be done by a qualified service technician. Call a service technician for any remedy that involves gas or electricity.
Error Code Table Error Fault Remedy 14 Thermal Fuse 16 Over Temperature Warning 32 Outgoing Water Temperature Sensor Fault 33 Heat Exchanger Outgoing Temperature Sensor Fault 34 Combustion Air Temperature Sensor Fault 52 Modulating Solenoid Valve Signal Abnormal Combustion Fan Failure Check gas type of unit and ensure it matches gas type being used. Check for restrictions in air flow around unit and vent terminal. Check for low water flow in a circulating system causing short-cycling.
Trouble Shooting for Common Issues , I don t have any hot water when I open the tap. Make sure there is gas, water, and electricity to the Rinnai water heater (power is turned on and the gas is turned on) When I was using the hot water, the water got cold. If you adjusted the flow from the tap to lessen it, you may have gone below the minimum flow required. The Rinnai Water Heater Requires a minimum flow rate to operate. (See the specification page for the flow rate of your model.
Flushing the Heat Exchange (Error Code: LC or 00) An “LC” or “00” error code indicates the unit is beginning to lime up and must be flushed. Failure to flush the appliance will cause damage to the heat exchanger. Damage caused by lime buildup is not covered by the unit’s warranty. After flushing, reset the LC fault code by turning off the power to the unit and turning the power back on. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. Disconnect electrical power to the water heater.
Installation Instructions Only properly trained and qualified installers should install this appliance. The warranty may be voided due to improper installation or installation by a nonqualified installer. Rinnai highly recommends all installers attend a product knowledge class.

Electrical Connection TERMINALS FOR CONTROLS The water heater must be electrically grounded in accordance with local codes or in the absence of local codes with the most recent edition of the National Electrical Code, ANSI/NFPA 70. In Canada, all electrical wiring should be in accordance with local codes and the Canadian Electrical Code, CSA C22.1 Part 1. Do not rely on the gas or water piping to ground the water heater. A screw is provided in the junction box for the grounding connection.
Gas Piping Pipe Sizing Procedure - Example The gas supply must be capable of handling the entire gas load at the location. Gas line sizing is based on gas type, the pressure drop in the system, the gas pressure supplied, and gas line type. Refer to the National Fuel Gas Code, NFPA 54, for proper gas line sizing. The below information is provided as an example. 1.
Water Piping General Instructions • A manual water control valve must be placed in the water inlet connection to the Rinnai water heater before it is connected to the water line. Unions may be used on both the hot and cold water lines for future servicing and disconnection of the unit. • The piping (including soldering materials) and components connected to this appliance must be approved for use in potable water systems. • Purge the water line to remove all debris and air.
Freeze Protection Piping Vacuum Breaker NOTICE Warranty does not cover damage due to freezing. With electrical power supplied to a Rinnai water heater, it will not freeze in environments as cold as -30ºF when protected from direct wind exposure. Rinnai Water Heater In the event of a power failure at temperatures below freezing the water heater should be drained of all water to prevent freezing damage. The unit may be drained manually.
