  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

 

The Operation Indicator will 
glow red when the appliance 
is ON and will glow green 
when the appliance is in 
STANDBY. 

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. 

When turned ON, the appliance will run at a flame 
level of 5 for 1.5 minutes, after which it will run at its 
last setting.  This will be a temperature setting or a 
flame level.  See Flame Function. 

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 causing the 
Operation Indicator to glow green. 

Pressing the ON/OFF button while the appliance is 
ON or in STANDBY will turn the appliance OFF.  The 
convection fan may continue to run for up to 15 
minutes after the appliance has been turned OFF in 
order to prevent the buildup of heat inside the 
appliance. 

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 1 second 
after a button is pressed and released 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 and released
