Fitur Utama:

• Propane Gas (LPG) Unit: Designed for use with liquid propane gas.
• Memulai Tekanan Air Rendah: 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.
• Ukuran Kompak: Dimensions are approximately 12.8 inches (front width) x 8 inches (depth) x 18.75 inches (height), allowing for flexible installation.
• Pengapian Otomatis: Powered by 2 D-size batteries (included) for automatic ignition upon water flow.
• Hemat Energi dan Air: Delivers hot water instantly, reducing waste.

2. Informasi Keselamatan

Langkah-langkah Instalasi:

1. Pemasangan: 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. Sambungan Air:
   • Hubungkan saluran pasokan air dingin ke Saluran Masuk Air Dingin.
   • Connect the hot water output line to the Saluran Air Panas.
   • Ensure all water connections are tight and leak-free. Use appropriate sealing tape or compound.
3. Sambungan Gas:
   • Connect the Propane (LPG) gas supply line to the Saluran Masuk Gas. 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. Pemasangan Baterai: Open the battery box and insert two D-size batteries. Ensure correct polarity. These batteries power the automatic ignition system.
5. Ventilasi: For indoor installations, ensure the area has adequate ventilation as this is a vent-free appliance.

4. Petunjuk Pengoperasian

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

Memulai Awal:

1. Ensure all water and gas connections are properly made and leak-free.
2. Buka katup pasokan gas utama.
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.

Operasi harian:

• 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. Pemeliharaan

Perawatan rutin memastikan umur panjang dan pengoperasian yang efisien dari pemanas air Anda.

Pemeriksaan Rutin:

• Penggantian Baterai: Replace the two D-size batteries annually, or if the ignition becomes inconsistent. Use high-quality alkaline batteries.
• Pemeriksaan Kebocoran: Periodically check all water and gas connections for leaks. For gas leaks, use a soapy water solution.
• Pembersihan Eksterior: Bersihkan bagian luar unit dengan lembut, damp kain. Jangan gunakan pembersih atau pelarut yang bersifat abrasif.

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. Matikan pasokan gas ke unit.
2. Matikan pasokan air dingin ke unit tersebut.
3. Open a hot water faucet in your system to relieve pressure.
4. Temukan 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.
