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.

• 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

• Restricted air filter indication lamp and audible reminder-Current model ENERGYSAVERS will flash a reminder lamp and emit an audible beep if it detects operational conditions indicative of a restricted air filter.

• Sealed Heat Exchanger-flame and combustion is sealed from the heating area

• 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. Upon resumption of power, the unit will automatically attempt to restart

• ENERGYSAVERS are equipped with an inline glass fuse and surge protection to protect from overcurrent or power surge www.foreverhotwater.com

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

• This calculation considers all factors that contribute to heat loss such as:

• Area and volume of the space to be heated

• Geographical location and climate where the furnace will be located

• Structural characteristics of the building such as number of windows, exterior doors, construction material, etc

• The Air Conditioning Contractors’ Association (ACCA) has an industry standard Btu calculation in their ―Manual J‖ publication

• A qualified and licensed installer should be familiar with this type of calculation

• Visit

http://www.acca.org/

for more information

• Rinnai also offers a basic DV sizing caluclator at

http://www.rinnai.us/heat_selector_2007.swf

• NOTE: Incorrectly sized applications can lead to the ENERGYSAVER shortcycling or failing to bring the area to the desired set point temperature www.foreverhotwater.com

ENERGYSAVER

®

—Whole House Furnaces

Key concepts

The ENERGYSAVER has the ability to heat an entire structure from a central room. Here’s how:

• 2 nd 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

1

• The variable gas valve and blower control modulate to ensure heat reaches the remainder of the structure without overheating the main area

• Cold air is detected quickly by the thermistor —mounted two inches above the floor and able to detect changes as small as 6/10 th ’s of a degree (Fahrenheit)

• These features aid in reducing stratification in the atmosphere (different layers of room temperature)

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

ENERGYSAVER

®

Direct Vent Furnaces

Operation Sequence

1. Combustion fan purges heat chamber, PCB verifies fan rotation

2. Ignition spark begins

3. When sensing electrode detects spark, gas valve assembly opens

4. Ignition occurs and heat exchanger warms

5. Spark stops as flame rod & PCB verify flame

6. When heat exchanger is warm enough, convection room blower circulates warm air into the structure.

7. When filled, the humidifier tray ensures the air is not too dry (if needed)

8. Thermistor & PCB determine gas and fan settings

9. When temperature set point is reached, if needed, gas valves close & combustion fan stops.

Convection fan continues to run to cool down unit.

10.When temperature drops, process starts over

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

• This reduction will not occur if the unit is undersized and cannot maintain the initial set point

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

• As a programmable furnace with two separate timers and a setback function

• The timers allow two separate heating events to be set

• Timer 1 and Timer 2 (individually or both as needed) can then be engaged to allow the unit to turn on and off for those events

• The ENERGYSAVER is designed to attempt to have the area at the set point temperature when the timer event begins —meaning it could turn on several minutes earlier to achieve set point temperature

• To set the clock and timers, see the installation manual

• 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.

• If Override is turned off, the unit will return to Timer operation www.foreverhotwater.com

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. This could cause the ENERGYSAVER

®

to use more gas to return to the set point and cancel any savings achieved

• This feature can also be used as frost protection during longer periods of vacancy (such as in a second home). For this use the setback temperature can be set as low as 38

°F

• Even when off, if the setback feature is engaged, the setback temperature will be maintained

• If power is lost and setback is ON, it will be ON at the resumption of power

The following example shows how, when used together, the timer and setback functions can maximize comfort and efficiency

• Daily schedule:

• Occupants wake at 5am

• Home is empty from 9am until 4pm

• Occupants are asleep from 11pm until 5am

12am 2am 4am 6am 8am 10am 12noon

• Operation temperature is set to 70°F

• Timer 1 is set from 5am to 9am

• Timer 2 is set from 4pm to 11pm

• Setback is set to 66°F

2pm 4pm 6pm 8pm 10pm 12am

Between timer events, the Setback temp of

66

°F is maintained

14

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. Therefore, a short power outage (a few minutes) will have virtually no effect on timer operations whereas a longer outage will require the clock to be reset. Dashes will initially display to indicate an outage occurred.

• 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

• If at some point after 15 seconds of established flame the flame fails, the unit will immediately attempt to relight with no code flashing

• If the unit cannot relight after this flame failure, code 11 will flash and the unit will try to ignite again in one hour

• If the unit continually or intermittently fails to ignite, a qualified service technician may be needed to determine the cause

• Each manual has a section named ―Restart Function‖ that explains this procedure

• Flame failure fault codes (code 12’s) are no longer needed due to this enhancement www.foreverhotwater.com

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.

• To view the last nine fault codes, with the unit OFF, press the UP, DOWN, and, ECONOMY buttons simultaneously
