Step 5: Combustion AirSystem: Blower and airpressure switch (continued)Note:The use of an inlet air filter is strongly recommended. Thesystem will perform longer and the settings will be morestable.Note:When selecting a 60 Hz Blower for use on 50 Hz, a pressureand capacity calculation is required. See Eclipse CombustionEngineering Guide (EFE 825).Inlet filter withreplaceable filterelementThe total selection information you should now have:• Blower model number• Motor hp• Motor enclosure (TEFC)• Voltage, number of phases, frequency• Rotation direction (CW or CCW).Air pressure switchThe air pressure switch gives a signal to the monitoring systemwhen there is not enough air pressure from the blower.You can find more information on pressure switches in BlowerBulletin 610Step 6: Main gas shut-offvalve trainMain gasshut-offvalve trainAir pressure switchWarning:Eclipse supports NFPA regulations, which requirethe use of an air pressure switch in conjunctionwith other safety components, as a minimumstandard for main gas safety shut-off systems.Consult EclipseEclipse can help you design and obtain a main gas shut-off valvetrain that complies with the current safety standards.The shut-off valve train must comply with all the local safetystandards set by the authorities that have jurisdiction.For details, please contact your local Eclipse representative orthe Eclipse factory.NoteEclipse supports NFPA regulations (two shut-off valves) as aminimum standard for main gas safety shut-off systems.Step 7: Process TemperatureControl SystemConsult EclipseThe process temperature control system is used to control andmonitor the temperature of the system. There is a wide varietyof control and measuring equipment available.For details, please contact your local Eclipse representative orthe Eclipse factory.18 Eclipse ThermJet PCA Design Guide No. 206, 3/5/07
