L. Detailed Component Operating Instruc-
tions - Intellifire™ Ignition
IntelliFire™, an ignition system exclusively featured in
Hearth & Home Technologies products, is an energy-
saving pilot ignition system for gas fireplaces and inserts.
It provides an ignition flame only when needed and has
a battery backup system that supplies power to spark the
ignition flame in the event of a power outage.
Intellifire
™
is an intermittent pilot ignition, which is an
electronic system. The term Intermittent is used because
the pilot burner flame is only present when the main
burner is operating. When the main burner is off the pilot
is also off.
NOTICE:
Batteries should not be placed in the battery
pack while using the transformer. Remove batteries before
using the transformer, and unplug the transformer before
installing the batteries. Battery polarity must be correct or
module damage will occur.
Appliance ON/OFF
A wall control is used to control the ON/OFF function
of the appliance. Follow instructions included with the
installed control.
Optional Fan Kit
If desired, a fan kit may be added. Contact your dealer
to order the correct fan kit. Heat management for the fan
is discussed in Section 3.J. Detailed instructions are in-
cluded with the fan kit.
