e. Multiply gas rate (cu ft./hr) by heating value (BTUh/cu ft.) to
obtain input.
If clocked rate does not match required input from Step 1, increase gas
valve outlet pressure to increase input or decrease gas valve outlet
pressure to decrease input. Repeat steps b through e until correct input is
achieved. Reinstall regulator seal cap on gas valve.
