CPI [Continuous Pilot Ignition] / IPI [Intermittent
Pilot Ignition] Jumper Cable Installation
"Why use CPI mode"?
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
building, 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. This Jumper Cable gives the Remote
Control the ability to operate the CPI / IPI switch and set the
unit to operate in either condition. 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 using the appliance.
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.
