➀ With horizontal louvers opened 30° from the vertical plane. WTC units have top and bottom piping connections, WSC units have side connections. All have copper tubes.
➁ V and PT models have copper tubes, VN and PTN models have cupronickel tubes. Mounting heights are maximum for heaters operating at standard conditions
(2 lbs. steam or 220°F water with 60°F entering air). Heights listed for Louver or Cone-Jet are with deflectors in fully-opened position. Refer to Figure 4.2 for correction of
mounting heights under other operating conditions. Maximum mounting height will be reduced as entering air temperatures exceed 60°F.

These correction factors are to be used as multipliers to correct the maximum recommended mounting heights of unit heaters when operated with steam pressures other
than 2 pounds or with water at other than average temperature of 220°F.
