IPI Electronic Ignition System
Overview
The IPI system is an advanced burner controller that
provides you with the option of having either a
Standing-Pilot, or an intermittent igniting system. This
alternating mode is controlled by the CPI/IPI Switch
(Continuous Pilot Ignition/Intermittent Pilot Ignition)
located on the IPI System Box. The difference between
a Standing-Pilot and an Intermittent-Pilot is in whether
the pilot stays lit or shuts off:
In Standing-Pilot, the pilot assembly is lit by the IPI
Main Module and continues to stay lit until 1) the
CPI/IPI Switch is switched to the IPI position; 2) a loss
of electrical power (battery and AC source), 3) the
flame sensor loses its signal, 4) the fuel supply discon-
tinues, or 5) the IPI Main Module malfunctions.
In the Intermittent-Pilot mode, the pilot shuts off when
the appliance is not in use. The advantage of this mode
is that fuel is not consumed when the fireplace is not
operating.
NOTE: In some jurisdiction, Intermittent-Pilot is
required. That means the pilot cannot remain lit when
the appliance is not operating.
Components
The core of the IPI system is the Main Module and the
IPI Valve. With these two components the system is
able to operate a gas fireplace. There are also other
components available to complement the IPI system.
IPI System Cover: Is essential in keeping the compo-
nents at their proper operating temperatures.
DO NOT
OPERATE THE APPLIANCE WITHOUT THIS
COVER.
Modulating Servo Motor: Is an add-on valve compo-
nent that permits HI/LO functionality to be controlled by
the remote. Contrary to this feature is a Manual HI/LO
Control Knob. The Modulating Servo Motor requires
the Remote system to be present.
Backup Battery Pack: This component permits the IPI system to operate without the need for an external AC Adapter
power source. The advantage to using the battery backup is that in the case of a power failure, the appliance is still
operable.
Remote Receiver: This component provides the capability of controlling the appliance with a wireless remote trans-
mitter. There are two switches to note on the receiver module:
The first switch on the Remote Receiver module is a 3-position slide switch. This switch is used to either manually
turn the main burner ON, activate the receiver to begin communication with the transmitter, or turn the main burner
completely OFF. The position of the slide switch designates these functions respectively.
The second is the small round pushbutton [PRG] used for programming the receiver to respond to a designated
remote. Therefore to program the system ensure that the transmitter is first turned OFF. Then, ensure that there is
sufficient electrical power going to the Receiver module and a fresh set of batteries in the transmitter. Now switch the
NOTE:
In certain instances the IPI Main Module requires resetting. This can occur if the system is unable to ignite
the pilot or the main burner in the allotted time period. The IPI is programmed to lockout all commands. To reset this
lockout you must deplete the system of all electrical power. This means to remove the batteries from the Battery
Pack, remove the batteries from the Remote Receiver (if applicable), and disconnect the AC Adapter from the sys-
tem. Leave the power off for approximately 25 seconds to clear its lockout.
