A Closer Look at the Technology
This tankless water heater incorporates several advanced components:
- Air Gas Mixer: Features an automatic combustion control system for optimized combustion and efficient condensation.
- Primary Heat Exchanger: Constructed from high-quality stainless steel with a low pressure drop and high efficiency oval tube & fin design.
- Secondary Heat Exchanger: Made from premium grade stainless steel.
- Condensate Trap: Collects condensation.
- Mixing Valve: The advanced modulating system ensures consistent water temperature, maintaining comfort within a 1°F increment.
- Turbo Fan: Ensures normal operation even with fluctuating voltage due to its low voltage running system.
- Air-Ratio Gas Valve: Works with the burner for precise fuel-air mixture.
- Metal-Fiber Burner: An Eco Pre-mixed burner designed for high combustion efficiency and low CO & NOx emissions.
- Main Control: Includes multiple safety functions, a dual-stage anti-freezing mechanism, and a Switched-Mode Power Supply (SMPS) design.
- State of the Art Gas Leak Detector: Shuts off the unit automatically in the event of a gas leak.
- Flow Control Valve: Automatically regulates water quantity based on the user's customized temperature setting, providing an optimal hot water experience.
Vent Termination Options
The unit supports various vent termination configurations to suit different installation requirements. Diagrams illustrate setups for intake air and exhaust venting, ensuring safe and efficient operation.
- Diagrams show typical installations with intake air drawn from outside and exhaust gases expelled.
- Options accommodate different building structures and venting distances up to 100ft with 3" Schedule 40 PVC, CPVC, or PP piping.
Multifunction Control Panel
The control panel provides user-friendly operation and diagnostics:
- Display: Shows Setting/Current Temperature, Rupture Prevention status, and Current status.
- Power ON/OFF Button: [Power Symbol] for turning the unit on and off.
- Current Status Indicator: Provides visual feedback on operation.
- Hot Water Temperature Control Button: Allows adjustment of the desired hot water temperature.
- Heating Water Temperature Control Button: For adjusting heating water temperature (e.g., for space heating).
- UP/DOWN Volume Controls: Used for setting Space heating, Hot water temperature, Timer functions, and other vacant settings.
The advanced technology of the Flow Control, Flow Sensor, and heat capacity control ensures DHW comfort by maintaining a constant temperature during usage.
