Adding Water to Humidifier:

So that you can humidify the air your RHFE-UNIT
is fitted with an enamelled tray behind the air
outlet. To fill the tray, open the door as shown
in the diagram and pour water into the tray using
the spout built into the door. The air will be
humidified as it passes over the water in the tray.
DO NOT FILL THE TRAY WHILE THE UNIT IS
IN OPERATION. CLOSE THE DOOR AFTER
FILLING. The RHFE UNIT is a very high
efficiency appliance,during operation a small
amount of water is produced in the vent tubes,this
drains into the enamel tray. It is quite normal for a
small quantity of water to remain in the bottom of
the tray.

Caution:

● The humidifier tray and the surrounding area are
hot when the unit is on. To avoid burns, do not add water to the tray while unit is on.

● Avoid adding water when the room is susceptible to condensation.

● If the water overflows from the water level hole when adding water, do not add any more water.

– 31 –

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 to overheat.

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

■ TYPES COMPATIBLE WITH EXTENSION SET

RHFE-1004FA
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 in pipe or hose.

■ HOW TO INSTALL

MODEL:RHFE-1004FA

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

– 53 –

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.

3˚ slope(approximate)

Less than 8 ft.

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

– 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
