Air for combustion is taken from outside
the room and the flue products are
exhausted outside, keeping the room air
clean.
Warm air flows from the bottom of the
appliance through the louvres, assisting
in even heat distribution. An integral
humidifier tray is built into the warm air
discharge duct.
The function will automatically operate the
appliance within one hour prior to the
programmed time of the Timer. This is
designed to heat a room to the pm-set
temperature by the programmed time.

turned OFF whilst the Child Proof lock is activated, it cannot be turned 434 again until the
lock is deactivated.
n AUTO COMFORT
A room temperature sensor located at the rear of the appliance is continuously monitoring the
temperature of the room. The main purpose of Auto Comfort is to improve control over the flow of
warm air being discharged through the louvres when the heater is first operated. The means by
which this control is achieved is an 8 speed modulating convection fan and the temperature sensor,
in conjunction with a micro-computer.
In order to achieve comfortable heating, it is preferable to avoid cold draughts from the appliance.
In the case of a conventional fan heater, the convection fan operates normally from the time of
ignition and a cool draught may accompany the flow of air from the appliance.
To overcome this situation, fuzzy logic controls the speed of the convection fan after taking into
consideration the room temperature at the time of ignition. For example: the room temperature is
low, then the fan rotates at low speed. As the room temperature rises the speed of the convection
fan gradually increases.
In this way it is possible to ensure a comfortable flow of warmed air, as well as decreasing the
sensation of cold draughts immediately after ignition.
The convection fan speed increases proportionally as the room gradually heats up. This improves
the warm air distribution, assisting in a reduction of warm air stratification throughout the room, and
resulting in more effective heating conditions.
The micro computer continuously monitors the room temperature and adjusts the convection fan
speed according to the conditions at the time.
-ll-

n FAN FILTER
To protect the room air fan from dust particles or
lint, a filter is situated at the rear of the appliance.
When this filter becomes blocked, the filter
indicator will flash to indicate that it should be
cleaned. Clean the filter weekly during the heating
season to avoid unnecessary strain on the
appliance.
Do not remove filter when appliance is
operating. When the filter requires cleaning,
clean filter before using the appliance, or whilst
the appliance is not operating.
If you do not clean the filter at regular intervals
and the filter indicator is allowed to remain
flashing, then the appliance will stop and [14] will
flash on the Digital Display signifying that the
inbuilt safety device has functioned. You must
clean the filter before operating the heater again.
n HUMIDIFIER TRAY
fsb that you can hum&My the air, your Rinnai RHFE-656tVl is fitted with an tanamelbedtray at
the bottom of the heater. If you choose to make use of tha humidifier tray, it will need filling
about once a day during the heatingseason. Do not fill the humtdlffer tray white the heater
cl
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-556FTFi 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.
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
riiht.
Note: these louvres are not designed to be
adjusted more than 6 times.

selected, the heater may operate anywhere within an hour prior to the programmed starting time of
the Timer.
The Preheat function will heat a room to the pre-set temperature by the programmed On
This function is called Pre-heat due to the way it operates. The room temperature is sensed one
hour before reaching the programmed time of either Timer.
The temperature differential at the time of sensing the room temperature, combined with the data
from the previous operation governs exactly how long before the programmed On time the micro
computer will operate the heater and ignite the burner.

These points are part of the normal operation of the unit.
H At Ignition:
Heater does not operate. -b
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 the
unit cuts down on the thermostat, or goes out.
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?
Are Timers set? Clear Timers and operate again.
+ 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 shot-ltime.
-b This is simply expansion noise from the heat exchanger.
n During combustion:
Clunking noise when the thermostat operates.
-I-,
