Delta Engineering 12lt Zero Start

R3,990.00

This unit is approved indoor and outdoor installation.

HOW IT WORKS!

  • Ignition is through 2 x type D torch batteries
  • Stainless steel flue (chimney) included in price
  • Open hot water tap – the water pressure pushes the light weight magnetic floater up and activates the geyser by signaling to the electronic box that there is spark and that the gas solenoid valve must open the gas to the main burners.
  • This type of geysers operates on low water pressure.  This model will only work with seperate taps and not mixers
  • To determine the size required is different to the diaphragm units. Simply do the following to assist you with choosing the correct size. This exercise is only if the water pressure is low.
  • Measure the water flow per minute at 2-3 different taps in and around the house. Measure one tap then also open multiple taps to see if the water flow rate per minute stays the same.
  • Once you have determined the water flow per minute you choose the size geyser accordingly to that.
  • Example: if you get around 10l per minute then you install a 9l zero start unit. Do not install an oversized geyser as it will over heat and shut down.
  • Works from 0.065 up to 8 bar water pressure
  • Once installed and you are ready to set the temperature, start by doing the following
  • Set the gas knob to minimum gas
  • Set the water inlet valve to maximum water flow.
  • Set the correct water temp by slowly increasing the gas.
  • This makes the zero start unit the most efficient on the market!!
  • It also has a LCD display to show the temperature of the water running through the heat exchanger.
  • Will not work with a mixer in shower unless you set the temperature to the desired setting and do not mix cold water to hot water.

This new generation zero type geyser has been redesigned with a more stable ignition system that reduces the chances of damage by sand and other impurities in the water.  It also offers many other positive attributes such as a more stable water inlet pressure and water flow.  It eliminates dry burn damage to the heat exchanger as well as battery drain.

IMPORTANT THINGS TO REMEMBER

  • Never step up the hot water pipe size bigger than 15mm.
  • You will need at least 12lts of continuous water per minute for this geyser to work.
  • Do not use toilet connectors for water in/out lets. Use 15mm inside diameter connectors.
  • Do not run the cold water supply from an electric geyser
  • Do not use orange hose as you will restrict the gas flow and increase the pressure resulting in gas starvation and the unit will not function correctly.
  • Use the correct size regulator.
  • Use correct size gas piping Sans10087-1
  • Ensure that the geyser is protected from water entering from the top as this will result in the electronic box and battery box being damaged.
  • Ensure to flush the water pipes before connecting it to the geyser. We recommend the gas installer to connect the water pipes.
  • Kindly make use of qualified gas installer to maintain warranty
