"Why use CPI mode"?
CPI means "Continuous Pilot Ignition" or "Standing Pilot" as
it is commonly known. IPI means "Intermittent Pilot Ignition",
which only initializes the pilot when you are going to be us-
ing the appliance.
There are several reasons why you may choose to use
CPI mode. When a flue is cold it can be difficult to light
the appliance. It can take a bit of time (particularly on tall
vents) to initialize vent action. This can result in "lifting" or
"ghosting" of the flames during the first two to three minutes
of operation. It is also possible to encounter times when
the fireplace fails to light successfully. The fireplace will
then attempt to re-light a second or third time depending
on prevailing temperatures or altitude. When in CPI mode
the pilot also keeps the system warm. During a "cold" start,
condensation will normally form on the inner glass surface
of the door. This condensation will quickly dry, however, the
condensation tends to run down the glass and cause some
streaking. CPI mode helps to resolve this issue. If CPI
mode is used during the winter months the energy it takes
to run the pilot is partially recovered as heat into the build-
ing, so it does not waste as much energy as running a pilot
in the off season.
A connector is supplied with this unit that can be plugged
into the controller. When the CPI jumper is plugged into the
controller wiring harness the pilot will light and run con-
tinuously. Use the wall switch to turn on the main burner.
Remove the CPI jumper to turn off CPI and return to IPI.
The difference between IPI and CPI:
IPI (Intermittent Pilot Ignition) Mode: is a fuel saving
mode in which the pilot is only used when the main burner
is on.
CPI (Continuous Pilot Ignition) Mode: The Pilot runs
continuously even when the main burner is off.

Installation
Installing the CPI Jumper Cable
1). Access the controller (refer to the installation and
maintenance manual for your model).
Figure 26.
2). Remove the bag containing the Jumper Cable from
the wiring harness connected to the controller as shown
in Figure 26.
Figure 26a.
3). Find the corresponding plug attached to the control
wire harness.
Figure 26b.
4). The pilot will light and burn continuously.
