Ensure each unit functions properly and calibrate.

C Test and Tune Boiler Burners using Natural Gas and Propane

1 Using a Calibrated stack gas analyzer, Combustion tune each boiler on Natural Gas at 5% intervals to ensure sufficient excess air throughout the firing range. Boilers are equipped with COHEN Gas Valves. Record boiler Data at all intervals (Stack Temp, % rate, O2, Steam Flow, Draft Gauge readings, etc.)

2 Using a Calibrated stack gas analyzer, Check the tuning of each boiler on the back up fuel supply (Propane) to ensure sufficient excess air throughout the firing range. Typically, at 20% intervals. Record all Data
