veried purchase price of the product itself. The maximum amount recoverable under this warranty is limited to the purchase

lation or occupancy date. The manufacturer’s warranty period for parts and labour for covered components is produced in
the following table.

appliances, and 10 years from the beginning date of warranty coverage for wood, pellet and coal appliances. These time
periods reect the minimum expected useful lives of the designated components under normal operating conditions.

automatically shuts down the replace after 9 hours of
continuous operation without receiving a command from
the remote control. If this occurs, restart the appliance.
NOTICE! Open windows for air circulation during re-
place break-in.
• Some people could be sensitive to smoke and odors.

H. Heat Management
Burn Rate
The 6X-AU model has a variable burn rate which is con-
trolled by the remote control. Therefore the ame height
is adjustable.
The ame height may be adjusted as desired by locating
the ame option on the remote control and adjusting up or
down to desired ame height.

NOTICE: Some functionality will be lost when using
battery backup including remote control, lights, or any
other auxiliary functions that require household 220/240
VAC power.
I. Operation During A Power Outage
The IntelliFire™ Plus intermittent pilot ignition system
comes with a battery backup system that enables the
system to operate in a power outage. The system offers
seamless transition from household AC power to battery
backup. A factory-installed battery pack is located in the
control cavity of the appliance. See Figure 3.5. Battery
longevity and performance will be affected by long term
exposure to the service temperatures of this appliance.
NOTICE: Batteries should only be used as a power source
in the event of an emergency power outage. Batteries
should not be used as a primary long-term power source.
To Operate Fireplace Using Battery Power (DC):
1. Access the control cavity of the appliance. See Figure
3.5 for location. Lift the decorative front off of the
appliance. Slide the ignition module ON/REMOTE/
OFF switch to the OFF position.
2. Locate the battery tray and insert four AA cell batteries.
See Figure 3.5. Battery polarity must be correct or
module damage will occur. A complete wiring diagram
is included in the Electrical section of the appliance
Installation Manual.
3. Turn the appliance on according to the instructions
below for the appropriate type of control:
Standard Wall Switch or Factory-Installed ON/OFF
Switch:
• Toggle the switch as you would under normal
circumstances.
Wireless Remote:
• Remote receiver is integrated into the ignition module
• Use the remote to turn the appliance on.
• To preserve battery life, do not use the HI/LO ame or
THERMOSTAT options.
Ignition Module:
• Locate the ignition module in the control cavity.
• Slide the ON/REMOTE/OFF switch to the ON position.
4. Replace decorative front on appliance.
To Return to Operation Using Electrical (AC) Power
Standard Wall Switch or Factory-Installed ON/OFF
Switch:
• Toggle the switch to OFF.
• Remove the batteries from the battery tray.
• Replace decorative front on appliance.
CAUTION! Risk of Overheating! Component heat shield
MUST be installed before operating appliance. Electrical
components will be damaged.
Wireless Remote:
• Slide the ON/REMOTE/OFF switch to the REMOTE
position.
• Remove the batteries from the battery tray.
• . Replace decorative front on appliance.
Ignition Module:
• Slide the ON/REMOTE/OFF switch to the ON position.
• Remove the batteries from the battery tray.
• . Replace decorative front on appliance.
CAUTION! Risk of Overheating! Component heat shield

6. Module Reset
This module may lock-out under certain conditions. When
this occurs, the appliance will not ignite or respond to
commands. The module will go into lock-out mode by
emitting three audible beeps, then continuously displaying
a RED/GREEN error code at its status indicator LED.
• Check battery tray. Remove batteries if installed. Batteries
should only be installed for use during power outages. See
Section I.
• Locate the module selector switch. (See Figure 3.6).
• Set the module selector switch to the OFF position.
• Wait ve (5) minutes to allow possible accumulated gas
to clear.
• Set the module selector switch to ON or REMOTE position.
• Start the appliance.
Nine Hour Safety Shutdown Feature
The appliance has a safety feature that automatically
shuts down the replace after nine hours of continuous
operation without receiving a command from the wall
switch or optional remote.
LED Lighting
The ON/OFF function for the LED lighting option is controlled
by the IntelliFire™ Plus remote control. Follow instructions
included with the installed control.
Appliance ON/OFF
Use the IntelliFire™ Plus Remote Control to control the ON/
OFF function of the appliance. Follow instructions included
with the installed control. If desired, a wall switch may be
installed to control the ON/OFF function of the appliance.
J. Control Module Operation
1. The control module has an ON/OFF/REMOTE selector
switch that must be set. See Figure 3.6.
OFF Position: Appliance will ignore all power inputs and
will not respond to any commands from a wall switch or
remote. The unit should be in the OFF position during
installation, service, battery installation, fuel conversion,
and in the event that the control goes into LOCK-OUT
mode as a result of an error code.
ON Position: Appliance will ignite and run continuously
in the HI ame setting, with no adjustment in ame
output. This mode of operation is primarily used for
initial installation or power outage operation with battery
backup.
REMOTE Position: Appliance will initiate commands
from an optional wired wall switch and/or the wireless
remote (RC300AU).
2. If using a wired wall switch with the module in REMOTE
mode, the ame output can be adjusted with the HI/LO
selector switch on the module. See Figure 3.6. Note
that the ame HI/LO selector switch will become inactive
once a remote control (RC300AU) is programmed to the
control module. Note that the control module will always
ignite the replace on HI and remain so for the initial 10
seconds of operation. If the HI/LO is switched to the
LO position, the ame output will automatically drop to
the lowest setting after the ame has been established
for 10 seconds. After this 10 second period, the ame
can be adjusted from HI to LO with the switch.
3. The control module has a safety feature that
automatically shuts down the replace after 9 hours
of continuous operation without receiving a command
from the RC300AU remote.
4. If you intend to use both an optional wired wall switch
and the RC300AU remote control to operate your
replace, the wall switch will override any commands
given by the remote.
5. The module has the capability to recognize potential
malfunctions. If these occur, it will fail to ignite and/
or respond to a command to ignite via the wall switch
and/or remote. In this case, the module may have
gone into LOCK-OUT mode. In this state, it will emit
a LED error code. To reset the error code, switch the
selector to OFF, and then back to REMOTE or ON. If
the ignition command again fails, the module will emit
an LED error code, prior to going back into LOCK-OUT
mode. Contact your dealer for service if this occurs.
Note: If the module is in LOCK-OUT mode, resetting the
circuit breaker to the appliance will also reset the module.
Note: For units installed in Australia, the residence’s 220/240
wall outlet to which this appliance’s power cord is connected,
must be wired to an in-line on/off switch. This is required for
servicing and/or resetting the control module in the event of
a control module LOCK-OUT.
