*IBR does not have procedure for rating pedestal mounted enclosures.
Dimensions in bold indicate metric units.
NOTE: Rating is Btu/hr/ft (Watts/meter) of finned length (for element dimensions see page 49). Hot water ratings determined by applying correction factor to steam ratings, are for
water velocities of 3 ft/sec (.91 m/s) or greater. See page 9, Chart S-1 for correction factors for water velocities other than 3 ft/sec (.91 m/s). For definition of installed height and heating
effect factors, see page 11. For heating ratings at other steam pressures and/or entering air temperatures, see page 10, Table S-2.
