Frequently Asked Question ("FAQ")
Q1: What are the differences between the ATI-510-N (ATI-510-I-N) and the ATI-510U-N (ATI-510U-I-N)?
A1.1: The ATI-510U-N adds a 3" flue opening for fresh air for combustion intake. The ATI-510-N took in fresh air from the grill at the bottom front of the heater.
1.2. The ATI-510-U complies with Ultra Low-NOX standards.
1.3. The water connections at the bottom of the heater are in different locations. The gas connection remains at the far right side.
