The spread shown for the heating mode is for a valve setting of 22° left deflection. *The maximum value given for spread for heating is that which
occurs at the ceiling height (8 feet). The cooling spread is a straight vertical column of air and is not shown. Throw and spread values are based on a
terminal velocity of 50 FPM.
