Operating Information

Turning the heater ON

When you press the ON/OFF button, the LED display will illuminate, the spark will ignite the main burner and the combustion fan will begin to run.

This heater has an automatic ignition system. When the main burner has lit, the combustion lamp will glow red, and the spark will stop.

If ignition does not occur after 15 seconds, the appliance will automatically turn off and fault code 11 will be displayed on the control panel. This may occur when using the appliance for the first time or if it has not been used for a while. Try operating the appliance again.

There may be a smell of burning dust or oil the first time the heater is lit or when the heater has been out of operation for a long time.

The appliance may make noises after ignition or when it is turned off. This is normal and is due to the thermal expansion or contraction of its components.

Adjusting the Temperature

The temperature setting and the room temperature are indicated by the L.E.D. display on the control panel. When the appliance is turned on the temperature setting will be displayed for 10 seconds. The display will then show the room temperature. The default temperature setting is 72 F.

To change the temperature setting press one of the temperature control buttons once. The Set Temp should light up and the display will show the current temperature setting. Continue to press the control buttons until the desired temperature setting is reached. After 10 seconds the display will return to showing the room temperature.

The thermostat automatically modulates the burner and the fan to maintain the temperature setting.

The temperature settings available are:

LO - burner is on minimum combustion

60 F - 80 F in two deg ree increments

HI - burner is on maximum combustion

Turning the heater OFF

Press the ON/OFF button. Do not turn off by unplugging at the power outlet.

The fan will continue to run for a short time to prevent the internal components from overheating.

Economy Mode

Pressing the Economy button will cause the appliance to go into Economy Mode and the green lamp will glow. This results in the temperature setting being reduced by 2 F, 30 minutes after the room temperature has reached the temperature setting. After another 30 minutes the temperature setting is reduced another 2 F. This could result in the temperature setting being reduced by a maximum of 4 F. The intent of this mode is to save energy.

Adjusting Air Flow Direction

The vertical louvers may be adjusted to move the air flow more to the right or to the left.

Use a screw driver or similar object to bend each louver to the desired position.

Do not bend repeatedly (no more than 5 times) or else the louver will break.

The horizontal louver (which determines the vertical air flow direction) is fixed and cannot be adjusted.

CAUTION

Do not adjust the air flow

louvers while warm air is flowing.

Sensible Temperature Control

The sensible temperature control feature allows comfortable heating which matches the conditions in the room.

Based on the information collected by the room temperature thermistor when the heating starts, the heating capacity is automatically adjusted to achieve a comfortable heating effect and to reach the temperature setting quickly.

Adding Water to the Humidifier

Warm air is humidified when it passes over the water in the tray.

Remove the bottom trim panel below the louvers by pulling on both sides. Pull the tray out and fill with water. Push the tray back in and attach the bottom trim panel.

During operation a small amount of condensation is produced in the flue system and drains into the humidifier tray.

CAUTION

Do not remove the

bottom trim panel or the humidifier tray while warm air is flowing.

Care and Maintenance

Filters

Dirty filters reduce the air flow and the appliance’s ability to produce heat. The filters should be cleaned frequently during the heating season. If the filters become blocked the filter indicator lamp will flash red. Eventually the appliance will turn off and display fault code 14 on the control panel display.

To clean the filters, the appliance should be OFF and cool. Remove the filter and clean it using a soft dry cloth or vacuum. If the filter is greasy wash with warm soapy water, rinse, and dry completely.

Maintenance

Repairs should be performed by a qualified service technician. The appliance should be inspected annually by a qualified service technician. More frequent cleaning may be required due to excessive lint from carpeting, bedding material, etc. It is imperative that control compartments, burners, and circulating air passage ways of the appliance be kept clean.

Any screen or guard removed for servicing the appliance must be replaced prior to operating the appliance. Clean as follows:

1. Turn heat off. Allow to cool for one hour.

2. Remove the front panel by removing six screws.

3. Use pressurized air to remove dust from the main burner, heat exchanger, and fan blades.

4. Use soft dry cloth to wipe cabinet.

Do not use wet cloth or spray cleaners on the burner.

The flue should be inspected annually for blockages or damage.

Motors are permanently lubricated and do not need periodic lubrication. Keep fan and motor free of dust and dirt by cleaning annually.

Verify proper operation after servicing.

Visual Inspection of Flame

Check that the burner flames are operating normally. The flame can be seen through the

circular window through the louvers.

When operating normally the burner flame should appear as long, clear, blue, stable, streaks. Yellow flames or an orange color is abnormal and maintenance is required.

NORMAL

ABNORMAL

Care of Exterior

Dampen soft cloth with warm water. Wring water out well and wipe the unit.

Do not use volatile substances such as benzene or thinners. They cause fading of the paint and deformation of the resin.

CAUTION

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.

Snow Accumulation

Keep the area around flue terminal free of snow and ice. The appliance will not function properly if the intake air or exhaust is impeded by obstructions.

Before Making a Service Call

Before making a service call please check the following:

■ At Ignition:

Heater does not operate.

Warm air does not flow when the burner lights.

Smoke or strange smells are produced on the first trial light up after installation.

Sharp clicking noises at ignition, or when unit cuts down on the thermostat, or goes out.

■ During Combustion:

Clunking noise when the thermostat operates.

Unit is not heating room.

Air filter is blocked or the louvers are blocked or obstructed.

Heater will not re-ignite after overheating.

■ When the unit is turned off.

Convection fan continues to run after turning OFF.

■ Other Points:

Steam is discharged from the flue terminal.

Unit cuts off without apparent reason.

Power Failure.

Is the heater plugged in? Have the fuses or breaker blown at the switch board? Is there a power failure? Is the air filter blocked? Is anything blocking the outlet for the hot air? Is the flue blocked?

The fan is started automatically after a short delay. This is to allow the heat exchanger to warm up, helping to avoid cold draughts.

This is caused by grease or oil and dust on the heat exchanger and will stop after a short time.

This is simply expansion noise from the heat exchanger.

This is the sound of the solenoid gas valves opening and closing.

Is the air filter blocked? Is the set temperature high enough? Is the warm air outlet blocked by anything? Are the doors and windows of the room closed? Was the appliance correctly sized for the space?

Allow heater to cool, clean air filter, operate again.

Even after unit has cooled down, the heater does not ignite again. Repair is necessary. Contact your local agent or Rinnai for a Service call.

This is to remove the residual heat from the heat exchanger. The fan will stop when the heater cools down.

High efficiency appliances tend to discharge water vapor on cold days. This is normal.

Check whether filters are blocked. Dirty filters will cause the heater to overheat.

Switch OFF, then ON again when power is restored to re-set controls.

Flue Manifold Installation

1. Disassemble the flue manifold

The flue consists of 3 parts:

sleeve

inside connection

outside terminal

Disassemble the flue manifold by first pulling out the inside connection. To remove the outer terminal pull and release the two internal ties and then pull out the outer terminal.

Clearance to combustibles for the sleeve and flanges is zero inches.

2. Adjust the sleeve length

Measure wall thickness through previously drilled 3 1/8 inch (80 mm) hole.

The end of the sleeve should protrude 3/16 3/8 inch (5-10 mm) from the outside wall.

The sleeve is threaded for adjustment. Adjust the sleeve length to wall thickness plus 3/16 3/8 inch (5-10 mm).

NOTE: Do not extend beyond the red line.

For other than the S type flue manifold, if a shorter length is necessary an extension can be removed. Cut the plastic and remove the extension.

The flue manifold must exhaust to the outside. Do not exhaust into other rooms.

The flue is not designed to be positioned under floors or below the heater.

This appliance can only be used with one of the five types of Rinnai flue kits. The flue kits and their dimensions are listed in the Specifications section.

Refer to the Flue Terminal Clearances section.
