*For outdoor models, change “ATI” to “ATO”. For propane models, change “N” to “P”
**For propane models, minimum is 13,000
***For propane models, minimum inlet gas pressure is 8.0 in. W.C. and maximum inlet gas pressure is 14.0 in. W.C.
† Cold climate represents 70°F temperature rise

Condensing Technology Provides Up to 0.95 Energy Factor
Ultra-Low NOx Emissions
• Complies with SCAQMD Rule 1146.2 NOx Emission Requirements Of 14 ng/J or 20 PPM.
Heat Exchanger
• Primary heat exchanger of the ATI/ATO-540 is constructed of a commercial-grade copper
that is more resilient to erosion.
• Copper is 25x better at heat transfer than stainless steel thus stabilizing outgoing water
temperature quicker and reducing pressure drop across the heat exchanger.
• Secondary heat exchanger is made of marine-grade 316L stainless steel to protect
against corrosion.
Maximum Flow Rates up to 10.0 GPM
Indoor Models
• Include integrated temperature controls with advanced diagnostics to simplify installation and
troubleshooting.
• Include factory-installed power cord.
Outdoor Models
• Include a wall mount temperature remote controller and advanced diagnostics to simplify
troubleshooting.
Safety Features
• Air-Fuel Ration (AFR) Sensor.
• Exhaust & Water Temperature Safety Control.
• Overheat Cut-off Fuse.
Internal Freeze Protection System
Power Vent or Power Direct Vent Design
Warranty
• 15-year limited warranty on heat exchanger in residential applications.
• 6-year limited warranty on heat exchanger in commercial applications.
• 5-year limited warranty on all parts.
