NOTES
The appliance will operate at reduced performance below 340 kPa water pressure.
For information relating to burner test point pressures and injector sizes refer to the name
plate located on the right hand side of the case for each model. (please refer to p.9)
For information relating to overall dimensions and connection points refer to diagrams.
(Please refer to p.6 & 7)
Installing in areas over 1500 m above sea level will reduce performance.

This manual provides information necessary for the installation, operation, and maintenance of
the water heater.
●
The model description is listed on the name plate which is attached to the right side of the case of
the water heater. (Please refer to p.9)
●
Please read all installation instructions completely before installing this product. ●
The Water Heater is an instantaneous, water heater designed to efficiently supply endless hot
water on demand.
●
The principle of the water heater is shown below: ●
3. INTRODUCTION
The diagrams are representative only and do not truly represent the physical product.
1. A hot water tap is turned on.
2. Water enters the water heater via the cold water inlet.
3. The water flow sensor detects the water flow.
4. The computer automatically ignites the burner.
5. Water circulates through the heat exchanger and is heated
6. The computer will modulate the gas supply valve and water flow to produce the right amount of hot
water at the correct temperature.
7. When the tap is turned off, the unit shuts down.
