Ključne karakteristike:

• 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.
• kompaktna veličina: Dimensions are approximately 12.8 inches (front width) x 8 inches (depth) x 18.75 inches (height), allowing for flexible installation.
• Automatsko paljenje: Powered by 2 D-size batteries (included) for automatic ignition upon water flow.
• Energy and Water Saving: Delivers hot water instantly, reducing waste.

4. Uputstvo za upotrebu

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

Početno pokretanje:

1. Ensure all water and gas connections are properly made and leak-free.
2. Otvorite glavni ventil za dovod plina.
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.

Dnevni rad:

• 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.

5. Održavanje

Redovno održavanje osigurava dugotrajnost i efikasan rad vašeg bojlera.

Rutinske provjere:

• Zamjena baterije: Replace the two D-size batteries annually, or if the ignition becomes inconsistent. Use high-quality alkaline batteries.
• Inspekcija curenja: Periodically check all water and gas connections for leaks. For gas leaks, use a soapy water solution.
• Eksterijerno čišćenje: Očistite spoljašnjost jedinice mekom, damp tkanina. Nemojte koristiti abrazivna sredstva za čišćenje ili rastvarače.

Winterization (Freezing Protection):

If the unit will be exposed to freezing temperatures, it is crucial to drain all water from the system to prevent damage.

1. Isključite dovod plina u jedinicu.
2. Isključite dovod hladne vode do uređaja.
3. Open a hot water faucet in your system to relieve pressure.
4. Locirajte Winter Drain valve at the bottom of the unit (refer to Figure 3.2). Open this valve to drain the water from the heat exchanger.
5. Once drained, close the drain valve.
