Notes:
1. Table is based on 1,000 Btu/cu.ft natural gas and elevation to 1000 feet.
2. Minimum gas pressure also applies to 200 fuel series.
3. As an option, the standard gas train can be replaced with an oversized design to reduce inlet gas
pressure requirements.
4. Use this column for all U.S. Installations.
5. Use this column for all Canadian Installations.
