8 Rinnai Corporation RHFE-750ETR
Sequence of Operations
The combustion fan will run for several seconds
before ignition to purge the combustion chamber of
any gas.
If the front burner fails to ignite the appliance will turn
off and fault code 11 will be displayed. If the rear
burner fails to ignite the appliance will turn off and
make another attempt to ignite. If this second attempt
fails, the appliance will automatically turn off and fault
code 11 will be displayed. 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.
The appliance may make noises after ignition or
extinction of the flame. This is normal and is due to
the thermal expansion or contraction of its
components.
If the ON/OFF or the STANDBY/ON button is pressed
immediately after the flame has been extinguished,
the appliance will delay ignition for about 1 minute.
The normal ignition sequence is as follows:
1. When the ON/OFF or the STANDBY/ON button is
pressed the Operation Indicator LED will glow red
and the combustion fan will rotate to purge the
combustion chamber.
2. Electric ignitor operates.
3. Gas is allowed to flow to the pilot when a spark is
sensed.
4. When the pilot flame is established gas will flow to
the front burners and then to the rear burners.
5. When all burners are established the appliance
will automatically maintain the temperature
setting.
NOTE: The appliance will wait until the heat
exchanger is warmed up before discharging
air. This ensures that any discharge air will be
warm and not cold.
Basic Fireplace Operations
Turning ON and OFF
The Operation Indicator will glow red when the
appliance is ON.
The appliance will turn ON -
and attempt ignition:
• when you press the ON/
OFF button on the
appliance panel while the
appliance is OFF.
• when you press the STANDBY/ON button on the
remote control while the appliance is in
STANDBY.
• at the TIMER setting after you have activated the
TIMER and while the appliance is in STANDBY.
Pressing the STANDBY/ON button on the remote
control while the appliance is ON will put the
appliance in STANDBY mode, extinguishing
all flames and cause the Operation Indicator
to glow green.
Pressing the ON/OFF button while the
appliance is ON or in STANDBY will turn the
appliance OFF.
Remote Control Operation
The remote control emits an infrared (IR) signal and
must be aimed at the receiver located to the right of
the warm air discharge louvers. The normal
operating range is about 16 feet (4.9 m) with an angle
of about 40 degrees to the horizontal. This range will
vary depending on the position of the installation and
the strength of the remote control batteries.
Signal transmissions are confirmed by
• a brief illumination of the Transmission
Signal Indicator on the Remote Display
• a flash by the Remote Control Receiver to the
right of the louvers
• a beep from the appliance
The remote control transmits information whenever a
button is pressed except as follows:
• when the lock function is activated
• when setting the timers, timer information is
transmitted only when the “TIME SET” button is
pressed
