Circular Fire Damper

The task of creating an HVAC Component is initiated from the HVAC Window.

Select Inline Plant Equipment in the Categories drop-down list and then CIRCULAR, Fire Damper in the Available Type drop-down list to display the Circular Fire Damper window:

You are required to input the following dimensions:

• FD Name(Ref)

• Duct Diameter

• Length

• Arrive Extension

• Leave Extension

• Curtain Height

• Right Width

• Left Width

• Bottom Width

To visualize how the dimensions equate to the actual piece of HVAC, click Picture to display a detailed drawing for Circular Fire Damper.

Note:
The fields will be pre-populated with default dimensions. These dimensions are governed by the details defined in the HVAC Catalog. The Manufacturer cannot be changed.

Specify a type of joint to use for the Arrjoint (Arrive Joint) and Leajoint (Leave joint). Refer to Create/Modify HVAC Component for a detailed description.

After selecting the type of joint to use for the Arrive Joint and Leave Joint you must enter the Curtain Direction.

In the Curtain Direction specify the axis that should be used. Valid axes are E (East), N (North), U (Up), -E (negative East), -N (negative North) or -U (Negative Up).

In the Position list, select Connect or Unchanged:

• Click Connect (default when Create is selected) - connects the piece of HVAC to the previous one.

• Click Unchanged (default when Modify is selected) - positions the component at the co-ordinates 0.00.

  Note:
  Unchanged is usually used, when Modify is selected, it does not connect the component but positions it at 0.00, in effect in a floating position.

Click Defaults to reset all the fields back to when the Circular Fire Damper window was opened.

Click Fit to orientate the Circular Fire Damper to automatically match the outlet (p-leave) of the previous piece of HVAC to the inlet (p-arrive) of the next piece.

Click OK to create the Circular Fire Damper component and close the Circular Fire Damper Window. You will be returned to the HVAC Window.

Click Cancel to discard all the field changes and close the Circular Fire Damper window.
