1. Ọja Ipariview
The EXCEL Tankless Gas Water Heater is designed to provide instant hot water for various applications, including small apartments, lofts, flats, RVs, and mobile homes. This unit operates on Propane (LPG) and features exclusive low water pressure startup technology, requiring only 2 PSI of water pressure to activate. Its vent-free design eliminates the need for complex and costly flue installations, making it a convenient and energy-efficient solution for on-demand hot water.

Awọn ẹya pataki:
- 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.
- Iwọn Iwapọ: Dimensions are approximately 12.8 inches (front width) x 8 inches (depth) x 18.75 inches (height), allowing for flexible installation.
- Imudanu aladaaṣe: Powered by 2 D-size batteries (included) for automatic ignition upon water flow.
- Energy and Water Saving: Delivers hot water instantly, reducing waste.

Ibẹrẹ Ibẹrẹ:
- Ensure all water and gas connections are properly made and leak-free.
- Ṣii akọkọ gaasi ipese àtọwọdá.
- Open a hot water faucet in your system. The unit will detect water flow (as low as 2 PSI) and automatically ignite.
- Allow water to run for a few moments to purge any air from the lines.
Isẹ ojoojumọ:
- 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.
