Running on up to 199,000 BTU\/h of natural gas input, it delivers on-demand hot water with a maximum flow rate of 10.5 GPM. The unit features built-in X3 Scale Prevention Technology, which protects the heat exchanger from mineral buildup and can extend heat exchanger service life by up to 300 percent compared to an unprotected unit. A built-in control display allows technicians to set operating parameters and read error codes directly from the unit. This model carries ENERGY STAR certification with a Uniform Energy Factor of 0.95 and complies with Ultra-Low NOx emissions regulations.\u003c\/p\u003e\n\u003cp\u003eThis unit is rated for residential installation and can be mounted indoors or outdoors. An outdoor vent cap kit is required for outdoor installation and is sold separately. For larger commercial-adjacent or multi-unit residential projects requiring higher hot water demand, up to 12 units of the same model can be cascaded together using the included cable. This flexibility makes the heater a practical choice for high-demand residential settings where a single unit may not cover peak load requirements. Licensed plumbers and HVAC technicians are the typical installing trade for this type of condensing tankless appliance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e199,000 BTU\/h natural gas input with a maximum flow rate of 10.5 GPM\u003c\/li\u003e\n  \u003cli\u003eBuilt-in X3 Scale Prevention Technology protects the heat exchanger from mineral buildup\u003c\/li\u003e\n  \u003cli\u003eENERGY STAR certified with a Uniform Energy Factor of 0.95\u003c\/li\u003e\n  \u003cli\u003eComplies with Ultra-Low NOx emissions regulations\u003c\/li\u003e\n  \u003cli\u003eBuilt-in control display for status monitoring and error code reading\u003c\/li\u003e\n  \u003cli\u003eCascade capability for up to 12 units using the included cable\u003c\/li\u003e\n  \u003cli\u003eRated for both indoor and outdoor installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis unit corresponds to model number ATM-199X3-N within the Adapt SC product line.
