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 discontinues, 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 jurisdictions 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 components at
their proper operating temperatures.
DO NOT OPERATE

Modulating Servo Motor: Is an add-on valve component 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.
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 system. Leave the power off
for approximately 25 seconds to clear its lockout.
Remote Receiver: This component provides the capability of controlling the appliance with a wireless remote transmitter.
Standing Pilot Mode for Colder Climates (Below Freezing)
For IPI models it may be necessary to set the appliance to Standing Pilot mode to maintain heat in the cavity. The purpose of this
procedure is to prevent cold air from penetrating the chimney and then onto the living space. Therefore, when the internal
temperature is slightly elevated the fireplace is able to freely exhaust its combustion and hence making it easier to startup.
