Steam Coil or Steam Integral Face and
Bypass (IFB) Coil
Steam coils are provided without valves as a standard unit,
requiring eld installation of valves and piping. As an option,
the steam coil is supplied with a two-way valve and actuator
motor from the factory. Refer to the submittal drawings to
determine unit conguration. The submittal drawing will also
have information about the line size connections.
The steam heat coil is pitched at 1/8ʺ (3 mm) per foot (305
mm) to provide positive condensate removal.
Refer to the certied drawings for the recommended piping
entrance locations. All piping penetrations must be sealed to
prevent air and water leakage.
NOTE: The valve actuator spring returns to a stem up
position upon power failure. This allows full ow
through the coil.
