9.1.1 Pilot Ignition Selection (IPI/CPI)

HI/LO PRESSURE MODULATOR KNOB

Model #BIR-20-LE (electronic ignition system) has the option of a continuous (standing) pilot. This features allows the system to change from a intermittent pilot ignition (IPI) system to a continuous pilot ignition (CPI) system. The standing (or continuous) pilot will keep the rebox warm and establish a draft in the vent, which allows the main burner to ignite with less air-ow disruption.

There are (2) rocker switches located on the gas valve housing in the control compartment. The main burner rocker switch is marked ‘B’ and the IPI/CPI pilot rocker switch is marked ‘P’.

• For intermittent pilot mode (IPI), set the IPI/CPI rocker switch to OFF. The pilot and main burner will ignite and turn o automatically when this IPI/CPI rocker switch is set to OFF.

• For continuous pilot mode (CPI), set the IPI/CPI rocker switch to ON. This will ignite the pilot only. The pilot will remain lit when the main burner ON/OFF rocker switch is pressed to OFF.
