1. Produk verbyview
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.

Sleutel kenmerke:
- 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.
- Kompakte grootte: Dimensions are approximately 12.8 inches (front width) x 8 inches (depth) x 18.75 inches (height), allowing for flexible installation.
- Outomatiese ontsteking: Powered by 2 D-size batteries (included) for automatic ignition upon water flow.
- Energy and Water Saving: Delivers hot water instantly, reducing waste.

Installasie stappe:
- Montering: 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.
- Wateraansluitings:
- Connect the cold water supply line to the Koue waterinlaat.
- Connect the hot water output line to the Warmwateruitlaat.
- Ensure all water connections are tight and leak-free. Use appropriate sealing tape or compound.
- Gasaansluiting:
- Connect the Propane (LPG) gas supply line to the Gas inlaat. 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.
- Battery installasie: Open the battery box and insert two D-size batteries. Ensure correct polarity. These batteries power the automatic ignition system.
- Ventilasie: For indoor installations, ensure the area has adequate ventilation as this is a vent-free appliance.

4. Bedryfsinstruksies
Follow these steps to operate your EXCEL Tankless Gas Water Heater.
Aanvanklike opstart:
- Ensure all water and gas connections are properly made and leak-free.
- Maak die hoofgastoevoerklep oop.
- 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.
Daaglikse werking:
- 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. Onderhoud
Gereelde onderhoud verseker die lang lewensduur en doeltreffende werking van u waterverwarmer.
Roetinekontroles:
- Battery vervanging: Replace the two D-size batteries annually, or if the ignition becomes inconsistent. Use high-quality alkaline batteries.
- Lek inspeksie: Periodically check all water and gas connections for leaks. For gas leaks, use a soapy water solution.
- Buitenste skoonmaak: Maak die buitekant van die eenheid skoon met 'n sagte, damp lap. Moenie skuur skoonmaakmiddels of oplosmiddels gebruik nie.
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.
- Skakel die gastoevoer na die eenheid af.
- Skakel die koue watertoevoer na die eenheid af.
- Open a hot water faucet in your system to relieve pressure.
- Vind die 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.
- Once drained, close the drain valve.

6. Probleemoplossing
This section provides solutions to common issues you might encounter with your water heater.
| Probleem | Moontlike oorsaak | Oplossing |
|---|---|---|
| Geen warm water / Eenheid ontbrand nie | No water flow or insufficient water pressure | Ensure water supply is on and water pressure is at least 2 PSI. Check for kinks in water lines. |
| Dooie of lae batterye | Replace both D-size batteries with new alkaline batteries. | |
| Geen gasvoorsiening nie | Ensure gas tank is not empty and gas supply valve is fully open. | |
| ODS or 20-minute safety shutoff activated | Ensure adequate ventilation. If unit ran for 20 minutes, close and reopen hot water faucet to reset. | |
| Water is nie warm genoeg nie | High water flow rate for incoming temperature | Reduce water flow rate using the control knob on the unit. |
| Lae inkomende water temperatuur | The unit adds approximately 45°F to incoming water. If incoming water is very cold, the output temperature will be lower. Reduce flow rate. | |
| Gas or water leaks | Los verbindings of beskadigde komponente | Tighten all connections. If leaks persist, contact a qualified professional for inspection and repair. Do not attempt to repair gas leaks yourself. |
Indien die probleem voortduur nadat u hierdie oplossings probeer het, kontak 'n gekwalifiseerde dienstegnikus.
