ON DEMAND PILOT LIGHT (SEVEN DAY SAFETY TIMER)
Important information if using the appliance in CPI (continuous pilot mode) only
This appliance is a ProFlame 2 system fitted with the “On Demand” Pilot, a safety feature which will shut down the gas valve completely
by extinguishing the pilot light in the event of a continuous full seven days of inactivity.
This only applies if the CPI (continuous pilot) switch is in the “on” position in your remote control transmitter.
Each time the main burner shuts down, manually or through the call from the thermostat, the seven day timer starts again.
The seven day inactivity timer is controlled within the circuit board. Therefore, if in CPI mode and when the pilot light is extinguished
after seven straight days of inactivity, the CPI setting on the remote control transmitter will remain in the “CPI” (continuous pilot) position.
Therefore, all that is required to relight the pilot would be to press the on/off button on the remote control transmitter from “on” to “off” and
back to “on”. Once the pilot has re-established operation will resume as normal. There is no requirement to do anything with the IPI/CPI
mode on the remote control transmitter.
If the unit never goes as long as seven full days without a call for heat, the pilot will remain lit until it is manually shut-off.
If the unit is being operated in IPI (intermittent pilot) mode, neither the above instructions nor the seven day timer will apply.
See the instructions in this manual and on the Lighting Instructions plate on the appliance to light or re-light the pilot.

The seven day inactivity timer is controlled within the circuit board. Therefore, if in CPI mode and when the pilot light is extinguished after seven straight days

If the unit is being operated in IPI (intermittent pilot) mode, neither the above instructions nor the seven day timer will apply.
See the instructions in this manual and on the Lighting Instructions plate on the appliance to light or re-light the pilot.

LOW BATTERY POWER DETECTION
Transmitter
The life span of the remote control batteries depends on various fac-
tors: quality of the batteries used, the number of ignitions of the appli-
ance, the number of changes to the room thermostat set point, etc.
When the Transmitter batteries are low, a Battery Icon will appear on
the LCD display of the Transmitter (Fig. 22) before all battery power is
lost. When the batteries are replaced this Icon will disappear.
Figure 22
CPI/IPI SWITCH
This appliance comes equipped with a CPI/IPI switch. The functions of
both the CPI/IPI switch are as follows:
Continuous pilot (CPI) - A pilot that when in operation, is intended to
remain continuously ignited until it is manually interrupted.
Intermittent pilot (IPI) - A pilot that is automatically ignited when an
appliance is called on to operate and which remains continuously
ignited during each period of main burner operation. The pilot is
automatically extinguished when each main burner operating cycle is
completed. The mode of the fireplace is easily changed from an inter-
mittent pilot ignition system (IPI) to a continuous pilot ignition system
(CPI) by using remote control as noted above.
The benefits of having as CPI are as follows:
- Keeps venting primed for trouble free start-up under colder weather
conditions or inversions.
- Keeps the unit glass warm, which decreases the amount of conden-
sation on start-up
-Provides owners with flexibility to choose a traditional continuous pilot.
The primary benefit of having the IPI function is a significant savings
on fuel as the pilot will only run when there is a call for heat.
Thermostat Icon: If the thermostat icon is not present on the remote
transmitter, follow instructions noted below:
1. Remove one battery from the remote.
2. Press and hold down the Thermostat button on the remote.
3. Reinstall the battery(removed in Step 1) while still holding down

low instructions noted below:
1. Remove one battery from remote.
2. Press and hold both the ON/OFF and MODE button at the same
time .
3. Reinstall battery removed in Step 1 while holding both buttons—
keep holding buttons, then release the MODE button only.
4. The screen will show either "Clr" or "Set" as the first option avail-
able is to disable or enable a mode.
