ADJUSTMENT PROCEDURE TO MAINTAIN 120°F INLET TEMP:

1.Turn on boiler and open valves A & B.

2.After steady-state operation, if T1 is less than 120°F, slowly close valve B until T1 climbs to 120°F.

3.If T1 is greater than 120°F, slowly close valve A until T1 drops to 120°F.

4.Check after system operating temperature has stabilized. Make final adjustments.
