IPI ELECTRONIC SYSTEM OPERATING INSTRUCTIONS

5.25 VDC ELECTRONIC CONTROL VALVE
The electronic control valve system includes the ability to switch
the pilot from a standing pilot mode to an intermittent pilot mode.
• IPI Mode - In the Intermittent Pilot mode, when the unit is
turned ON, it will cause spark to the pilot, light the pilot,
then allow the burner to light. When the unit is turned to
OFF, both the burner and pilot will be OFF.
• CPI Mode - In the Continuous Pilot mode, the pilot re-
mains ON continuously even when the burner is turned
OFF.
Note: A small toggle switch is located on a bracket that is used to
switch from IPI (upward position) to the CPI (downward position).
See Figure 38.
When the unit is turned to ON, the electrical current will energize
a spark to the pilot igniter. Once the pilot sensor heats up (after a
few seconds), the valve will be energized, allowing gas to flow to
the burner.

1. Follow the SAFETY and LIGHTING INSTRUCTIONS for In-
termittent Pilot controls found in this manual, and on labels
found in the control compartment located in the lower cavity
of the appliance.
2. During the operating season (or in power outage periods), it is
recommended that the pilot remain in the CPI (standing pilot
mode) to reduce cold start issues, and/or conserve battery
backup power during a power outage.
3. The gas valve has inlet and outlet pressure taps as shown in
Figure 38. Refer to page 15 for gas pressure requirements.
Note: The gas control has a manual HI/LO flame adjustment
knob (regulator) that allows you to increase or decrease
the height of the burner flame. See Figure 38. Rotate
the HI/LO knob counterclockwise to "HI" to increase the
flame height, and clockwise to "LO" to decrease the flame
height.
OPTIONAL REMOTE CONTROLS
Optional remote controls are available for use with this appliance.
To connect the remote receiver to the appliance, first disconnect
the ON/OFF switch wires from the white and green wire connec-
tors and connect the wires from the remote receiver to the green
and white wire connectors. See Figure 38.
Follow the instructions included with the remote control for pro-
gramming and other operational information.
