Spark Safety Device: Automatically shuts unit down when there is an abnormal spark at time

of ignition. Display lamps “LOW”, “60”, and “64” will activate if this happens.

Flame Failure Device: Activated when burner flame fails, indicator lamp “ON” flashes. If

burner fails to ignite, indicator lamp “60” flashes. This prevents raw gas from being released.

Overheat Switch: This device automatically cuts the gas off if the heater exceeds a

predetermined temperature. This is normally caused by an obstruction in front of the louvers, or a blocked fan filter. Indicator lamp “68” “ON” and the “FILTER” indicator lamp flash when overheat switch is activated.

Two Fusible Links: Backs up the overheat switch. If the fusible link cuts the unit off, a

service call by an authorized person is required to replace the link. Indicator lamps “68” , “FILTER” and “ON” will flash.

PRE-SERVICE CHECK

Before asking for a service call please check the following points. These points are part of the normal operation of the unit.

■ 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?

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 of overheat.

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

■ TYPES COMPATIBLE WITH EXTENSION SET

RHFE-431FA INSTALLING AN EXTENSION KIT

Installing an extension kit requires construction of an air line and the exhaust line. The air line is connected between the Air Supply Elbow at the rear of the heater and the air inlet port on the Flue pipe. Similarly, the exhaust line is connected between the joint pipe at the rear of the heater, and the exhaust port on the Flue pipe.

Caution: Check to see there is no debris inpipe or hose.

■ HOW TO INSTALL

MODEL:RHFE-431FA

Example:Using 2 sets of extension set and 1 bent set. Example:Using 80 inches slide pipe set.

1. How to connect exhaust pipes

2. How to connect air intake hose

To connect the exhaust pipes, fit the male end into the female end and clamp with pipe stopper A to prevent slipping. The exhaust pipe can be telescoped to the required length; do not cut it.

Screw hose joint half of its length onto the air intake hose, then screw another air intake hose into the joint. The hose can be cut to the required length.

IMPORTANT: The PVC air line is longer than the exhaust line and may need to be cut to size. Be sure, however, to thoroughly deburr all rough edges.

・Set the air intake hose and exhaust pipe into the pipe

clamps, screw the clamp onto the wall fixture, and affix to the wall with screw B.

・The air intake hose and exhaust pipe can also be

screwed onto the wall using the pipe clamp and the nut.

With the exhaust pipes inserted into the ends, bend the bent pipe to the angle reguired for installation. This part is mainly used for curves and for connection to vent terminal.

■ CAUTIONS

1. Maximum extendable length

FOR BEST ROOM AIR HUMIDITY, KEEP WATER IN THE HUMIDIFIER TRAY.

・13 feet, 2 bends ・The bend where the hose and pipes leave the body is

not counted.

・The air intake hose should run along the exhaust pipe.

2. To prevent water condensation

CAUTION

Never allow the exhaust pipe to sag, as condensed water may accumulate and cause incomplete combustion.

3. Condensed water formed by combustion, will run back to the unit, and may overflow from the condensation pan if pipes are longer then 8 feet. Therefore, pipes exceeding these lengths should be made to drain to the outside by giving their horizontal portions 3˚ or more downward and outward slope.

Condensed water may accumulate here, and cause a blockage preventing combustion.

3˚ slope(approximate)

Less than 8 ft.

Page 57

– 55 –

4. Wherever the air intake hose and exhaust pipe run sideways, try to have the exhaust pipe on top (to prevent the air intake hose from sagging onto the exhaust pipe).

QUALIFIED INSTALLING AGENCY

The installation must conform to local codes, in the absence of local codes, the installation must conform with American National Standard (National Fuel Gas Code) known as NFPA 54 and ANSI Z223.1.1992. Available from the American National Standards Institute, Inc., 1430 Broadway, New York, N.Y. 10018 or from the National Fire Protection Association, 470 Atlantic Avenue, Boston, Mass. 02210.
