I. Operation During A Power Outage
The IntelliFire intermittent pilot ignition system comes
with a battery backup system that enables the system
to operate in a power outage. A factory-installed battery
pack is located in the control cavity of the appliance. See
Figure 3.6. Batteries should not be placed in the battery
tray while using electrical power to operate the fireplace.
Remove batteries from battery tray when power has been
restored.
To Operate Fireplace Using Battery Power (DC):
1. Access the control cavity of the appliance. See Figure
3.6 for location. The decorative front may need to be
removed.
2. Locate the battery tray and insert two D cell batteries.
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.
Multifunctional Wired Wall Switch Control System:
• Locate the wired wall switch control module in control
cavity.
• Locate battery operation switch on the side of the
module.
• Slide the switch to the BATTERY ON or ON position.
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.
NOTICE:
Some functionality will be lost when using battery
backup including remote control, fan, lights, or any other
auxiliary functions that require household 110-120 VAC
power.
H. Heat Management
Heat Output
The Mercury models have a variable burn rate which is
controlled by the HI/LO knob on the gas valve. Therefore
the flame height is adjustable. The HI/LO knob is shown
in Figure 3.6. It is located in the control cavity of the
appliance. The HI/LO knob may be adjusted as desired
by turning clockwise to the HIGH position and by turning
counterclockwise to the LO position.
If an optional fan is installed, the fan speed is controlled
by adjusting the speed control knob. Turn the knob to
increase the fan speed as desired.

Some IPI systems have a safety feature that
automatically shuts down the fireplace after 9 hours of
continuous operation without receiving a command from
the remote control. If this occurs, restart the appliance.
