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 remains
ON continuously even when the burner is turned OFF.
•
The pilot will shut off after 7 days if there is no activity or
call for heat.
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 33.
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 33.
Refer to pages 18 and 19 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 33.
Rotate the HI/LO knob coun-
terclockwise 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.
Follow the instructions included with the remote control for pro-
gramming and other operational information.
