Features and Benefits • When sized correctly, the ENERGYSAVER® Furnace can be used as a whole house/primary heat source.
Features and Benefits • The unit’s standby power consumption is less than 1 watt. • Seven-stage Intelligent Modulating Gas Valve and blower control. • Warm air discharge at floor level. o Directional louvers to optimize direction of air flow. • Ultra-quiet operation-Decibel range of 27-47 is comparable to a normal conversation. • Gas type is field convertible. • Restart Functions allow automatic restart after ignition, combustion, or power failures. • Small 3” diameter concentric vent.
Safety Features • Self Diagnostic Circuitry-Should the ENERGYSAVER® detect an unsafe operating condition, the unit will shut down and a fault code will display indicating the specific issue. o If the code is due to an ignition or combustion failure, the unit will attempt to relight automatically. • Function/Child Lock • Cool to the touch Cabinets.
Safety Features • Overheat protection- Multiple temperature sensors monitor the appliance’s temperature. Shut down occurs if an unsafe operational temperature is detected. • Combustion and convection fan validation-should either of these fans fail to maintain the proper speed (likely due to a restriction), the PCB will not allow the unit to operate. • Electronic ignition-no standing pilot. • Power failure protection-Should the ENERGYSAVER lose power, the gas supply will automatically close.
ENERGYSAVER® Sizing To ensure the ENERGYSAVER operates as designed, an industry standard Btu heat loss calculation must be performed on the area to be heated.
ENERGYSAVER®—Whole House Furnaces Key concepts The ENERGYSAVER has the ability to heat an entire structure from a central room. Here’s how: • 2nd law of thermodynamics – Heat seeks cold • Once the main room approaches the set point temperature, the heat begins to move to other rooms—seeking cold. • The variable gas valve and blower control modulate to ensure heat reaches the remainder of the structure without overheating the main area.
ENERGYSAVER®—Whole House Furnaces Key concepts • Variable speed technology – Modulating gas and air based on the heat loss at that moment • With on/off single stage operation, gas usage can be high due to alternating periods between maximum flame and no flame at all • The Energysaver’s modulating technology has the ability to replace only the heat escaping the structure by continuously operating at heating levels based on the demand at that moment On / Off Single Stage Heating Appliance Continuous-Run Mo

Economy Function Economy Mode is designed to save gas usage over time. • The Economy Function is based on the theory that the human body cannot detect small temperature changes over an extended period of time. • 30 minutes after the set point temperature is achieved, the unit will reduce the temperature by 2°F. After 30 additional minutes, the unit will reduce the temperature an additional 2°F. • The maximum temperature reduction will not exceed 4°F.
Clock, Timer, and Setback Functions (C-Series) C-Series ENERGYSAVERS® have two primary methods of operation: • Exclusively as a thermostatically controlled furnace • When left to operate on a continuous-run basis using feedback from its thermostat, the ENERGYSAVER will achieve an optimum balance between comfort and efficiency.
Clock, Timer, and Setback Functions (C-Series) • If needed, the Override button can be selected to temporarily turn on or off the timers to allow manual operation. • If the unit is operating during a Timer’s event, pressing Override will turn the unit off until the next Timer’s event. • If the unit is off between Timer events, pressing Override will turn it on. It will continue to run until the end of the next Timer’s event and return to Timer operation.
Clock, Timer, and Setback Functions (C-Series) Setback allows a minimum temperature to be pre-set and maintained between timer events or while the unit is turned off. • This feature’s primary function is to slightly reduce the temperature (and gas usage) during extended periods of nonuse or inactivity—such as sleeping or when the home is empty. • NOTE: When this feature is used as a setback function for energy savings, it is not advisable to reduce setback more than 4-6°F from the regular set point.
Restart Features All ES, EX, and C-Series models will attempt restart after a power failure or flame failure to ensure heating is not interrupted for extended periods of time. • If there is a power failure while the appliance is operating, the unit will attempt to restart automatically when the power is restored. • The timers will retain their settings after a power outage. • After an outage, the clock will retain the time at that moment until power resumes.
Restart Features • Should a high gust of wind, gas outage, etc. occur that affects the flame characteristic, the unit will automatically shut down, purge the combustion chamber, and re-ignite. • If the unit cannot ignite or maintain flame for 15 seconds after ignition, code 11 will flash and the unit will try to ignite again in one hour. • This code will not be stored in the fault code history.
Fault Codes • A fault code will flash on the unit when a fault occurs. The unit will stop operating. • Operation intervention is required for all codes EXCEPT a code 11.
Warranty and Maintenance • Warranty Rinnai ENERGYSAVER® Furnace Warranty Heat Exchanger Coverage Parts Reasonable Labor 10 years 5 years 2 years Refer to each model’s installation and owner manual for full warranty details • Maintenance and Service • The appliance should be inspected at least annually by a qualified service technician—see the installation manual for full details. • The exterior can be cleaned with a damp, warm cloth.
High Altitude and Gas Conversion • All units are approved up to 10,200 feet. • The Installation manual and the conversion manual supplied with each unit has instructions for high altitude settings. • High altitude conversion does not require additional or replacement parts—only a simple manifold gas pressure adjustment. • Only a dual port manometer will be required to complete this adjustment. • All EnergySaver® furnaces can be field converted from NG to LP or LP to NG.
Maximum Temperature Limit • All ENERGYSAVER® models now have the ability to set a maximum temperature limit directly from the control panel. This procedure is NOT in the manuals to allow property owners and managers to control this setting as needed. • This is beneficial to landlords and property management to conserve energy and reduce unnecessary gas consumption.
