Eclipse Linnox Model CCS-LS, Installation Guide 159, 2/20/04146. Check the setting of the maximum gas pressure switch andthe minimum air pressure switch. The maximum gas pressureswitch is adjusted 20% higher than the maximum gas pressureon the burner. The minimum air pressure switch is adjusted toapprox. 20% of the maximum air pressure.The air pressure depends on the selected combustion airblower. Please refer to the related project documentation.1. Ensure that the process air blower is running.2. Ensure that the manual isolating ball valve is closed.3. Initiate the electrical supply to start the operating sequence.The combustion air blower will start running. If the sequenceis operating correctly, the programmer will run through tothe point of ignition, the safety shut-off valves will open and,in absence of a flame, will proceed to a lockout condition.Danger:If simulated limits or simulated flame failures donot shut down the fuel system within the requiredresponse time, immediately correct the problembefore proceeding.Note:On multiple burner systems with a central combustion airblower, one should remember that the combustion air pressurewill change, depending on the total air demand.If one burner is adjusted, it is advised to set the combustionair of all other burners to at least 50% of the maximumcapacity if not in operation. This will prevent flame failures orinability to reach the high fire capacity when the installation isswitched to normal operation.Low fire air adjustment procedure:1. Start the combustion air blower.2. Drive control motor to low fire position (activate the manualswitch or lock first).3. Measure air differential pressure between tap (Pa) and theprocess tap (Pp).4. Adjust low fire air if necessary.Note:The slot at the end of the BV (air damper) shaft indicates theposition of the BV. The BV is closed when the shaft slot isperpendicular to the direction of air flow through the BV.For adjustment of the BV, adjust the lever mechanism.Step 2: Dry runStep 3: Combustion air check
