Негизги өзгөчөлүктөрү:

• Propane Gas (LPG) Unit: Designed for use with liquid propane gas.
• Low Water Pressure Startup: Activates with as little as 2 PSI of water pressure, ideal for areas with fluctuating water supply. This is achieved through a magnetic water flow sensor, unlike older units that rely on rubber diaphragms requiring higher pressure.
• Vent-Free Technology: Does not require a traditional flue or ductwork for exhaust. Equipped with an Oxygen Depletion Safety (ODS) shutoff and an exclusive 20-minute safety shutoff feature for indoor installation with proper ventilation.
• Компакт өлчөмү: Dimensions are approximately 12.8 inches (front width) x 8 inches (depth) x 18.75 inches (height), allowing for flexible installation.
• Автоматтык от алдыруу: Powered by 2 D-size batteries (included) for automatic ignition upon water flow.
• Энергияны жана сууну үнөмдөө: Delivers hot water instantly, reducing waste.

4. Иштөө нускамалары

Follow these steps to operate your EXCEL Tankless Gas Water Heater.

Алгачкы ишке киргизүү:

1. Ensure all water and gas connections are properly made and leak-free.
2. Негизги газ берүүчү клапанды ачыңыз.
3. Open a hot water faucet in your system. The unit will detect water flow (as low as 2 PSI) and automatically ignite.
4. Allow water to run for a few moments to purge any air from the lines.

Күнүмдүк операция:

• To get hot water, simply open any hot water faucet connected to the unit. The heater will automatically ignite and begin heating water as it flows through.
• The unit is designed for a temperature rise of approximately 45°F, delivering 1.6 Gallons Per Minute (GPM).
• While suitable for multiple points of use, it is recommended to use no more than one point of use at a time for optimal performance.
• For incoming cold water temperatures below 50°F (down to 40°F), you may need to reduce the water flow rate using the control knob to achieve desired hot water temperature.
• The unit features a 20-minute safety shutoff. If hot water is continuously drawn for more than 20 minutes, the unit will automatically shut off. To restart, close the hot water faucet and then reopen it.
