K = Minimum 0.5” [13 mm]
H = 0.5” [13 mm] + maximum total static pressure
X = 3.9375” [100 mm] if unit has a 6” [152 mm] tubular steel base
L = H + K + pipe diameter + insulation − X

H = 1” [36 mm] (for each 1“ [25 mm] of maximum negative static pressure) + 1” [25 mm]
J = Half of H
X = 3.9375” [100 mm] if unit has a 6” [152 mm] tubular steel base
