5. POST-INSTALLATION SETUP AND CALIBRATION
Following installation of all Low NOx Conversion Kit items, it will be necessary to adjust several
operating parameters using the unit’s Control System menus. In addition, combustion calibration
procedures MUST be performed to ensure Low NOx compliance, prior to placing the unit into service.
The procedures in this section are divided into the following main categories:
• Low NOx Operating Parameter Menu Changes
• Combustion Calibration Setup
• Combustion Calibration Procedures for Units With C-More or Modular Control Systems
• Combustion Calibration Procedures for Units With Digital (CCC) Control Systems
• Unit Reassembly
These procedures are provided in paragraphs 5.1 through 5.5 respectively. For more detailed
information on the operation of your KC1000 unit, refer to the applicable Operation & Maintenance
Manual for the installed Control System as follows:

NOTE
If the KC1000 is equipped with an older style Digital (CCC) Control System,
no menu changes are required.
5.1 Control System Menu Changes for Low NOx Operation
If the KC1000 is equipped with either a C-More or Modular Control System, several menu changes
may need to be made to ensure Low NOx compliance. These changes will depend on which type of
control system is installed and whether the unit is a boiler or water heater.
5.1.1 Post-Purge Timeout For C-More Control System
If the unit is equipped with a C-More Control System, adjust the Post-Purge Timer in the Factory
