Remote Control System
The remote control and receiver allow you
to command the functions of your fireplace
from the comfort of your chair. They are
configured to control the primary burner
operation, its flame levels (through six levels)
and provide ON/OFF and smart control of
this appliance.
The control board connects directly to the
gas valve and stepper motor (see Wire
Diagram on
Page 18
).
The control is powered by four (4) AA batteries in
the wall switch and/or 120 VAC line power.
The control accepts commands via radio
frequency from the transmitter and does not
require line-of-sight operation.
The ON/REMOTE/OFF switch can be set to
one of three positions:
• ON (manual override)
• REMOTE (remote control)
• OFF
Initializing the System for the First Time
Install four (4) AA batteries into the receiver
battery bay, behind the wall switch plate.
NOTE: Install the batteries into the battery
bay as indicated on the battery cover.
Ensure that batteries are installed with
proper polarity (+/-).
Place the ON/REMOTE/OFF switch in the
REMOTE position (see
Figure 3
on
Page 10
).
Insert the end of the paper clip (or other
similar object) into the hole marked "PRG"
on the receiver front cover. The control
board, located in the fireplace, will "beep"
three (3) times to indicate that it is ready to
synchronize with a transmitter.
CAUTION: Property damage hazard.
Excessive heat can cause property
damage. The appliance can stay lit for
many hours. Turn off the appliance if it
is not going to be attended for any length
of time. Always place the Transmitter
where children can not reach it. Control
will automatically shut off after 24 hrs of
continued operation
Temperature Indicator Display
With the system in the OFF position, press
the Room Temperature Key and the Mode
Key at the same time (see
Figure 4
on
Page 10
). Look at the LCD screen on the
transmitter to verify that a "C" or "F" is visible
to the right of the Room Temperature display
(see
Figure 5
on
Page 10
).
Turn ON the Appliance
With the receiver switch in the REMOTE
position, press the ON/OFF Key on the
transmitter. The transmitter display will show
all active icons on the screen. At the same
time, the receiver connects to the gas valve
coil and the appliance main burner turns on.
A single "beep" from the receiver will confirm
reception of the command.
Turn OFF the Appliance
Press the ON/OFF Key on the transmitter. The
transmitter LCD display will only show the
room temperature and icon. At the same time,
the receiver disconnects the gas valve coil
and the appliance burner turns off. A single
"beep" from the receiver confirms reception of
the command.
Remote Flame Control
The system has six (6) flame levels. See
Figure 6
on
Page 10
for an example. With
the system on, and the flame level at the
maximum in the appliance, pressing the
Down Arrow Key once will reduce the
flame height by one step until the flame is
turned OFF.
The Up Arrow key will increase the flame
height each time it is pressed. If the Up
Arrow key is pressed while the system
is ON but the flame is OFF, the flame will
come on in the high position (see
Figure 7
on
Page 10
). A single "beep will confirm
reception of the command.
Install three (3) AAA batteries in the
transmitter battery bay, located on the base
of the transmitter. With the batteries installed
in the transmitter, push the ON button. The
receiver will "beep" four (4) times to indicate
the transmitter command has been accepted
and is set to the particular code of that
transmitter. The system is now initialized.
Low Battery Power Detection
The life span of the receiver batteries
depends on various factors:
• Quality of the batteries used
• Number of ignitions of the appliance
• etc.
When the receiver batteries are low, no
"beep" will be emitted from the receiver when
it receives an ON/OFF command from the
transmitter. This is an alert for a low battery
condition for the receiver. When the batteries
are replaced the "beep" will be emitted
from the receiver when the ON/OFF key is
pressed (See Initializing the System for the
First Time).
When the transmitter batteries are low, a
battery icon will appear on the LCD display
of the transmitter before all battery power is
lost. When the batteries are replaced this icon
will disappear.
WARNING
Fire Hazard. Can cause severe
injury or death. The receiver
causes ignition of the appli-
ance. The appliance can turn on
suddenly. Keep away from the
appliance burner when operating
the remote system or activating
manual bypass of the remote
system.
