E HUMIDIFIER TRAY
I Y
So that you can humidify the air, your Rinnai RHFE-556FM is fitted with an enamelled tray at
the bottom of the heater. If you choose to make use of the humidifier tray, it will need filling
about once a day during the heating season. Do not fill the humidifier tray while the heater
is running.
\ /
II
1 To fill the humidifier tray:
Remove the bottom trim panel, below the louvres,
by pulling on both sides. Simply pull the tray
forward to allow it to be filled with water. The
warm air will be humidified as it passes over the
water in the tray. Refit the bottom trim panel after
filling the tray. The RHFE-556FM is a very high
efficiency appliance, during operation a small
amount of condensation is produced in the flue
system, this drains into the enamelled humidifier
tray.
\
he humidifier has the benefit (when filled with water) of raising the humidity in the air. With increased
humidity, the heater can actually be run at a lowsr temperature white still maintaining the same level
n VERTICAL LOUVRE ADJUSTMENT
The warm air flow direction may be altered by
inserting a screwdriver or similar tool and gently
bending the vertical louvre(s) either to the left or the
right.
Note: these louvres are not designed to be
adjusted more than 6 times.

Before asking for a service call please check the following points.
These points are part of the normal operation of the unit.
n At Ignition:
Heater does not operate. 1 + 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?
Is the central timer turned off? (where fited)
Warm air does not flow when the burner lights. + The fan is started automatically after a short delay.
This is to allow the heat exchanger to warm up,
helping to avoid cold draughts.
Smoke or strange smells are produced on the
first trial light up after installation.
+ This is caused by grease or oil and dust on the heat exchanger
and will stop afler a short time.

unit cuts down on the thermostat, or goes out.
n During combustion:
Clunking noise when the thermostat operates. This is the sound of the solenoid gas valves opening and
closing.
Unit is not heating room. + 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?
Air filter is blocked or the louvres are blocked
or obstructed. Allow heater to cool, clean air filter, operate again.
Heater will not re-ignite after overheating. + 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.
n When the unit is turned off:
Convection fan continues to run after turning OFF. --) This is to remove the residual heat from the heat exchanger, the
fan will stop when the heater cools down.
S Other Points:
Steam is discharged from the flue terminal. --) High efficiency appliances tend to discharge water vapour on
cold days, this is normal.
Unit cuts off without apparent reason. -+ Check whether filters are blocked, dirty filters will cause the
heater to overheat.
Power Failure. + Switch OFF, then ON again when power is restored to
re-set controls.

1. Disassemble Manifold from Sleeve.
The flue consists of 3 parts, sleeve,
inside connectors and tube, outside
terminal; (dis-assemble by pulling hard on
outside terminal and inner connections,
then pull sleeve off outer terminal).
2. Adjustment of Sleeve Length.
Measure wall thickness through
previously drilled 80 mm hole.
End of sleeve should protrude 5-10 mm
from outside wall. Adjust sleeve length to
wall thickness plus 5 -10 mm. (Sleeve is
threaded for adjustment).
3. For A and AA flues only
Depending on flue set and wall thickness
extension piece “C” may need to be
removed.
Cut plastic, remove extension, then follow
instruction 2.
This applies to “A” and “AA” flues only.
There is no extension on other flues, they
can be fully adjusted by turning the
threaded section.
4. Fixing Sleeve.
Fix to the wall, using the 3 screws
provided.
NOTE:
The flange is marked “TOP”, sleeve
must be fitted with this mark UP.
Check sleeve protrudes 5-10 mm on
the outside.
