DELTA ENGINEERING 20 LITRE ZERO START

Key Features:

• Indoor/Outdoor Installation: Suitable for various installation locations.
• Battery Ignition: Uses 2 x type D batteries for ignition.
• Included Flue (Chimney): Provides safe venting of combustion gases.
• Water Pressure Activation:
  • Water flow triggers a magnetic floater, activating the ignition and gas valve.
  • Operates on low water pressure (0.065 bar to 8 bar).
  • Compatible with mixers.
• Sizing Based on Flow Rate:
  • Measure the water flow rate (liters per minute) at multiple taps.
  • Select a geyser size that matches the measured flow rate.
  • Avoid oversizing to prevent overheating and shutdown.
  • Example: 10 liters per minute flow rate requires a 9 liter per minute geyser.
• Temperature Adjustment:
  • Start with minimum gas and maximum water flow.
  • Gradually increase the gas to achieve the desired temperature.
• LCD Temperature Display: Shows the output water temperature.
• "Jet-Fin" Type B Design:
  • Replaces the older "Zero Start" model.
  • Improved ignition system, resistant to damage from impurities.
  • Stable water inlet pressure and flow.
  • Reduced risk of "dry burn" damage to the heat exchanger.
  • Reduced battery drain.
• Zero start unit: This means the unit only activates when a hot water tap is opened.

How it Works (Simplified):

1. Water Flow: Opening a hot water tap initiates water flow.
2. Activation: Water pressure activates a magnetic floater.
3. Ignition: The electronic control box triggers a spark from the batteries.
4. Gas Flow: The gas solenoid valve opens, supplying gas to the burners.
5. Heating: The burners heat the water as it passes through the heat exchanger.
6. Temperature Control: Adjusting the gas flow controls the water temperature.
7. Display: The LCD shows the output water temperature.

Key Improvements of "Jet-Fin" Type B over "Zero Start":

• Enhanced ignition system for increased durability.
• More stable water flow and pressure.
• Improved protection against heat exchanger damage.
• More efficient battery usage
