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.
