Why Aqua-Chem Cleaver-Brooks CB Boiler burner stays in low fire?
If the burner in your Aqua-Chem Boiler stays in low fire, it could be due to: * Pressure or temperature above modulating control setting. * Manual-automatic switch in wrong position. * Inoperative modulating motor. * Defective modulating control. * Binding or loose linkage, cams, setscrews, etc.
How to troubleshoot modulating motor that does not operate in Aqua-Chem Cleaver-Brooks CB Boiler?
If the modulating motor in your Aqua-Chem Boiler isn't working, consider these possibilities: * Manual-automatic switch in wrong position. * Linkage loose or jammed. * If the motor doesn't drive to open or close during pre-purge or close on burner shutdown: the motor could be defective, there might be a loose electrical connection, or the damper motor transformer could be defective. * If the motor doesn't operate on demand: the manual/automatic switch could be in the wrong position, the modulating control might be improperly set or inoperative, the motor could be defective, there might be a loose electrical connection, or the damper motor transformer could be defective.
Why Aqua-Chem Cleaver-Brooks CB has no ignition?
If your Aqua-Chem Boiler has no ignition, possible causes include: * **Lack of spark:** This may be due to a grounded electrode, cracked porcelain, improper electrode setting, loose terminal on the ignition cable, a shorted cable, an inoperative ignition transformer, or insufficient voltage at the pilot ignition circuit terminal. * **Spark but no flame:** This could be due to a lack of fuel, an inoperative pilot solenoid, insufficient voltage at the pilot ignition circuit terminal, or too much air. * **Low fire switch open:** The damper motor may not be closed, the cam might have slipped, or the switch could be defective. The damper could also be jammed, or the linkage binding. * **Running interlock circuit not completed:** Combustion or atomizing air proving switches could be def...
