Adjusting the Flame Height -
Operates in ON or THERMO mode
This remote control system allows the user to control the
height of the FLAME when the gas valve is factory equipped
with a FLAME CONTROLLER.
1. Press and release FLAME button to change flame height
to HI (see Figure 7, Location #5), (a second flame icon
appears).
2. Press again to return flame to normal state.
Low Battery Indicator
An “X” outlined by a battery on the right side of the LCD
screen will appear when battery power has dropped sig-
nificantly. At this time, approximately two weeks of battery
power remains.
Child Proof Lockout (CP)
The transmitter contains a “Child Proof” lockout feature
that prevents unauthorized use of the remote control. To
access the “Child Proof” activation button, remove cover
on BACK of transmitter. To activate LOCKOUT:
1. Press and hold in the “setting button” for 5 seconds. The
letters CP will display on the LCD screen (see Figure
8). This prevents the activation of fireplace. When any
function button is pressed ON/OFF etc. the letter CP
will display on the LCD screen.
To deactivate LOCKOUT:
1. Press and hold in the “setting button” for 5 seconds. The
LCD will display CP until 5 seconds have elapsed, and
then the LCD screen will return to its normal state.
TRANSMITTER SAFETY FEATURES
It is recommended that the TRANSMITTERS always be
located within a 20 foot operating range of the fireplace,
preferably in the same room in which the fireplace system
is located. The TRANSMITTER features several safety
features that alert the user when the TRANSMITTER is
placed outside the 20 foot normal operating range.
Thermo-Updating and Communication-Safety Features
This remote control has a COMMUNICATION-SAFETY
function built into its software. It provides an extra margin
of safety when the TRANSMITTER is out of the normal
20 foot operating range of the receiver. It is also activated
when the batteries become weak or are removed from the
transmitter.
In the THERMO-UPDATING feature (only in the THERMO
or TIMER modes) the transmitter normally reads the ROOM
temperature every 2 minutes. In addition to checking the
temperature, the transmitter sends a signal to the receiver
indicating that the transmitter and its batteries are still ac-
tive.
In the COMMUNICATION-SAFETY feature, at all times and
in all OPERATING MODES the transmitter sends a signal
every fifteen (15) minutes to the receiver, indicating that the
transmitter is within the normal operating range of 20 feet.
Should the receiver NOT receive a transmitter signal every
15 minutes (COMMUNICATION-SAFETY feature), the RE-
CEIVER will begin a 2 HOUR (120 minute) countdown tim-
ing function. If during this 2 hour period, the receiver does
not receive a signal from the transmitter, the RECEIVER
will shut down the fireplace being controlled by the receiver.
The RECEIVER will then emit a series of rapid “beeps”.
Then, after 10 rapid “beeps”, the RECEIVER will continue
to emit a single “beep” every 4 seconds until a transmitter
signal is again received. The intermittent 4 second beeping
will go on indefinitely until reset.
To “reset” the RECEIVER and operate the fireplace system:
1. Press the MODE button on the transmitter. The word
ON must display on the LCD screen. The COMMUNICA-
TION -SAFETY operation is overridden and the system
will return to normal operation depending on the MODE
selected at the transmitter.
We recommend the user check the batteries in the TRANS-
MITTER to make sure the voltage is no less than 2.7 volts.
Auto Shutdown
This remote control has an Auto Shutdown feature incor-
porated into its system. When the transmitter MODE is
in the ON position the fireplace will continuously operate
for 9 hours. After 9 hours, the fireplace will shut down. To
relight the fireplace:
1. Press the MODE button. The fireplace will operate
continuously for up to 9 hours before Auto Shutdown
repeats cycle. The Auto Shutdown signal comes from
the transmitter. The transmitter must be positioned
within a 20 foot operating range for the Auto Shutdown
feature to operate.
SYSTEM CHECK
Millivolt Valves
Light the appliance following the lighting instructions that
came with the fireplace. Confirm that the pilot flame is on.
It must be in operation for the main gas valve to operate.
1. Slide the 3-position button on the remote receiver to the
ON position. The main gas flame (i.e., the fire) should
ignite.
2. Slide the button to OFF. The flame should extinguish
(the pilot flame will remain on).
3. Slide the button to REMOTE (the center position), then
press the MODE button on the transmitter to change
the system to ON. The main gas flame should ignite.
4. Press the MODE button on the transmitter to change
the system to OFF. The flame should extinguish (the
pilot flame will remain on).
5. Press the MODE button on the transmitter to change
the system to THERMO.
6. Advance the SET temperature on the transmitter to a
temperature of at least 2º F (1º C) above the ROOM
temperature displayed on the LCD screen and the
system flame will ignite.
