BEFORE YOU BEGIN  
Read this entire manual before you use your new fireplace (especially the 

section “Safety Precautions” on page 2).  Fail-

ure to follow the instructions may result in property damage, bodily injury, or even death. 

 

Remote Control Transmitter Functions 

 

NOTE

: The Wall Receiver will “beep” once every time 

a Remote Transmitter Key is pressed, signaling that 
the command has been received. 
Identify the four function buttons on the Remote 
Transmitter:  

ON/OFF KEY

: This button turns the sys-

tem ON or OFF. When this button is 
pressed and the system is OFF, the pilot 
light will stay ON if 

the “Standing Pilot 

Switch” is in the ON position. 
 

THERMOSTAT KEY

: This button, when 

pressed after the ON/OFF KEY is pressed and the system is ON, will allow the selection of three modes: 
Manual Operation, Normal Thermostat and Smart Thermostat. 

Manual Mode

: In this mode, the room tempera-

ture is ignored and the fireplace can be turned 

ON indefinitely. The room temperature rise has no effect on 
this mode.  All other functions such as fan speed control, 
flame height control, secondary burner On/OFF control and 
Accent Light ON/OFF controls will be manually controllable. 

Normal Thermostat

: In this mode, the fireplace will stay 

functioning until the room temperature increases 1

o

F above 

the Set Point Temperature. To increase the Set Point Tem-
perature, Press the UP button until the desired temperature 

is 

displayed in the SET POINT TEMPERATURE window. The 
fan will turn on 5 minutes after fireplace startup and will turn 

off 

12-1/2 minutes after the flames turn off, in this mode. The 
flame height can be adjusted while the fireplace is function-
ing, fan speed can be adjusted after 5 minutes of startup. 
Secondary burner can be turned On or Off at any time after 
startup. The Accent Light can be turned on or off any time 
after startup. 

Smart Thermostat

: In this mode, all other functions except the flame height adjustment are allowed. Manual flame height 

adjustment is not allowed in this mode.  The Smart Thermostat function adjusts the flame height in accordance to the dif-
ference between the set point temperature and the actual room temperature.  As the room temperature gets closer to the 
set point temperature, the Smart Function automatically modulates the flame down.  

 
UP/DOWN KEY: 

This key is used to increase or decrease the Set Point Temperatures, Flame Height and Fan Speed and 

to toggle between Accent Light ON/OFF and Secondary Burner ON/OFF

MODE SELECTION KEY: 

This key is used to toggle between the various function icons : Flame Height, Fan Speed, Ac-

cent Light and Secondary Burner.
