WARDFlex/WARDFlexMAX Sizing Table Generator

The WARDFlex/WARDFlexMAX Sizing Table Generator is designed to allow users to create custom sizing tables to assist in the design of a WARDFlex/WARDFlexMAX fuel gas piping system. Using this sizing table generator a user will be able to create a custom sizing table for a natural gas or propane system with custom gas supply pressures and pressure drops. Users may also specify longer run length and/or different length increments than those shown in the Design and Installation Guide. Natural gas tables will display capacities of WARDFlex/WARDFlexMAX in Cubic Feet per Hour (CFH) while propane tables will display capacities of WARDFlex/WARDFlexMAX in Thousands of BTU (kBTU). See the instructions below for assistance using this sizing table generator.


  1. Choose a gas type.
  2. Choose a supply pressure and pressure drop. You must specify the units for each.
  3. Choose the minimum and maximum length and the length increment.
  4. Press the “Generate Table” button.
