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. 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.
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.
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.
Remote Receiver: This component provides the capability of
controlling the appliance with a wireless remote transmitter. 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 slide switch to the middle [REMOTE] position and then push the small pushbutton to begin
programming. Bring the transmitter close to the receiver and then press the power button [ ] on the transmitter. An audible
beep will sound to indicate the system is programmed and ready to be used.
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. Check with your local jurisdiction to determine which
system is permissible.
