1. Umkhiqizo Uphelileview

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.

Umfanekiso 1.1: Ngaphambili nangaseceleni view of the EXCEL Tankless Gas Water Heater, showcasing umklamo wayo omncane kanye nezinkinobho zokulawula.

Izici Eziyinhloko:

• 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.
• Usayizi Ohlangene: Dimensions are approximately 12.8 inches (front width) x 8 inches (depth) x 18.75 inches (height), allowing for flexible installation.
• Ukuthungela okuzenzakalelayo: Powered by 2 D-size batteries (included) for automatic ignition upon water flow.
• Ukonga Amandla Namanzi: Delivers hot water instantly, reducing waste.

2. Ulwazi Lokuphepha

Read and understand all safety warnings and instructions before installing, operating, or performing maintenance on this appliance. Failure to follow these instructions could result in property damage, personal injury, or death.

Izinyathelo Zokuphepha Ezivamile:

• Le divayisi kumele ifakwe uchwepheshe oqeqeshiwe ngokuvumelana nayo yonke imithetho nemigomo yendawo.
• Ensure adequate ventilation when installing the unit indoors due to its vent-free design.
• Ungagcini noma usebenzise uphethiloli noma omunye umhwamuko ovuthayo noketshezi eduze kwalesi noma esinye isisetshenziswa.
• Check for gas leaks using a soapy water solution after installation and during maintenance. Never use an open flame.
• The unit is equipped with an Oxygen Depletion Safety (ODS) shutoff system and a 20-minute safety shutoff feature. Do not bypass or tamper ngalezi zisetshenziswa zokuphepha.
• Ensure proper battery installation for automatic ignition. Use new, high-quality D-size alkaline batteries.
• Protect the unit from freezing temperatures. Drain the unit if it will be exposed to freezing conditions (see Maintenance section).
• Lo mkhiqizo uqukethe amakhemikhali aziwa yiSifundazwe SaseCalifornia ukuthi abangele umdlavuza kanye nokukhubazeka kokuzalwa noma okunye ukulimala kokuzala (Isexwayiso se-Proposition 65).

3. Ukusetha nokufakwa

Proper installation is critical for the safe and efficient operation of your EXCEL Tankless Gas Water Heater. Refer to the diagrams below for connection points.

Ukuhlonza ingxenye:

Figure 3.2: Location of the Winter Drain and Battery Box.

Izinyathelo zokufaka:

1. Ukukhweza: Securely mount the unit to a wall using appropriate hardware. Ensure the mounting surface can support the weight of the unit when filled with water.
2. Izixhumanisi Zamanzi:
   • Connect the cold water supply line to the Ukungena kwamanzi abandayo.
   • Connect the hot water output line to the I-Hot Water Outlet.
   • Ensure all water connections are tight and leak-free. Use appropriate sealing tape or compound.
3. Uxhumano Lwegesi:
   • Connect the Propane (LPG) gas supply line to the I-Gas Inlet. The unit includes an LPG Brass Fitting for a ⅜" Flare connection.
   • Verify all gas connections are secure and test for leaks using a soapy water solution.
4. Ukufakwa Kwebhethri: Open the battery box and insert two D-size batteries. Ensure correct polarity. These batteries power the automatic ignition system.
5. Ukungenisa umoya: For indoor installations, ensure the area has adequate ventilation as this is a vent-free appliance.

4. Iziqondiso Zokusebenza

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

Ukuqala kokuqala:

1. Ensure all water and gas connections are properly made and leak-free.
2. Open the main gas supply valve.
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.

Ukusebenza kwansuku zonke:

• 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. Isondlo

Ukunakekelwa njalo kuqinisekisa ukuphila isikhathi eside nokusebenza kahle kwesifudumezi sakho samanzi.

Ukuhlola Okujwayelekile:

• Ukushintshwa Kwebhethri: Replace the two D-size batteries annually, or if the ignition becomes inconsistent. Use high-quality alkaline batteries.
• Ukuhlola Ukuvuza: Periodically check all water and gas connections for leaks. For gas leaks, use a soapy water solution.
• Ukuhlanza Ingaphandle: Hlanza ingaphandle leyunithi ngesithambile, damp indwangu. Ungasebenzisi izinto zokuhlanza abrasive noma izincibilikisi.

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. Vala ukunikezwa kwegesi kuyunithi.
2. Vala amanzi abandayo angena kuyunithi.
3. Open a hot water faucet in your system to relieve pressure.
