["P03 is the low-fire position. Before setting the desired low-fire position, it is important to set the proper high-fire fuel rate with the gas servo at the  maximum position. Ideally this will be done using a fuel-flow meter. If the burner can be isolated as the only appliance drawing gas, the meter can be clocked to approximate fuel flow and the calculated burner head pressure (using Bernoulli's principle) can be used. To get to the high-fire position at P03, slowly move all of the servos to the high-fire positions. To do this safely, trim each servo a small amount at a time with an analyzer connected. Do not save this point! At the high-fire position, note the servo positions and burner head pressure below and make any adjustments to the gas regulators to achiever the correct input gas flow.
