10.1.1 Pilot Ignition Selection (IPI/CPI)
Model #BAY-36-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. For installations that
require a seven day time-out, see information about pilot ignition in
Section 10.1.1.1 below.
There are (2) rocker switches located on the gas valve housing in the
control compartment. You will need to remove the bottom frame to
access this. The main burner rocker switch is marked ‘B’ and the IPI/CPI
pilot rocker switch is marked ‘P’. See Figure 10.1 below.
• 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.
• When nished, the bottom frame must be reinstalled to maintain
clearances.
10.1.1.1 7 Day Time-out installations (LE)
For regions that require installation of a 7 day time-out counter (refer
to your local dealer to see if this applicable to your installation),
model #BAY-36-LE is tted with a control system equipped with a
time-out counter set for 7 consecutive days once the pilot has been
ignited.
• If you have your Proame 2 system set to CPI (continuous pilot
ignition) with 7 consecutive days without ignition of the main
burner, the pilot will turn o, but the pilot (marked ‘P’) rocker
switch will still be set to ON.
• You must manually cycle the pilot rocker switch to put the sys-
tem back to CPI mode. First, turn the ‘P’ rocker switch OFF, then
ON, to re-activate the CPI mode.
NOTE: Figure 10.1 shows the CPI/IPI mode control switch (pilot
rocker switch, marked ‘P’) is already in the ON position. It has
rst to be turned OFF, then back ON, to re-activate the CPI mode
together with the the 7 day Time-out counter.
• This a standard safety feature of the SIT Proame 2 system.
• Once you turn CPI on, the 7 day timer will start. If at any time
during the following 7 days your main burner ignites, it will reset
the timer back to 7 days.
• See 10.1.1 Pilot Ignition Selection (IPI/CPI) above to select your
preferred pilot ignition feature. To operate the appliance, see the
