TRANSMITTER
Important: Before operating remote control, trans-
mitter and receiver must have matching security
codes. See section ‘Matching Security Codes’.
Important: Review‘Communication-Safety Features’
under‘Transmitter SafetyFeatures’ section.The com-
municationsafetyfeatures shutdownthe fireplacesys-
tem when a potentially unsafe condition exists.
Important: Review ‘Auto Shutdown’ section. This
safetyfeature shutsdown thefireplace after9 hoursof
continuousoperation, in ONmode only.
Important: New or fully charged batteries are essen-
tial for proper operation of the multi-function transmit-
ter. The transmitter operates on 2AAA-size 1.5V bat-
teries.UseAlkalinebatteriesfor longerbattery life and
maximumoperational performance.
Insert 2AAA-size 1.5V batteries into the battery com-
partmenton theback ofthe transmitter. When thebat-
teries are correctly inserted, the screen will display
numbers(see Figure 5for LCDDisplay Screen).
NOTE: If the transmitter is activated from a very cold
condition it may be necessary to allow the transmitter
to stabilize to room temperature (could take up to 15
minutes) before accurate room temperatures are dis-
played on the screen.
NOTE: LCD screen is equipped with a “backlite” for
easierviewingofLCDscreen.Backlite illuminateswhen
afunctionbuttonisdepressed.After5 secondselapses,
LCD screen will return to its normal state.

MATCHING SECURITY CODES
It may be necessary to program the remote receiver
to the security code of the transmitter upon initial use,
if batteries are replaced, or if a replacement transmit-
ter is purchased from your dealer. To program the re-
mote receiver:
1. Set the slide button on the receiver to the REMOTE
position.
2. Push the LEARN button (one beep will be heard)
on the top of the remote receiver.
3. Then press the MODE button on the transmitter.
Several beeps indicate the transmitter’s code has
been programmed into the receiver. When an ex-
isting receiver is matched to a new transmitter, the
new security code will overwrite the old one. NOTE:
When the LEARN button is depressed, “beeping”
sounds should be heard. If no “beeping” is heard
check to see that the receiver has 110-120VAC
power to it.
If you are unsuccessful in matching the security code
on the first attempt, wait 1-2 minutes before trying
again.
