HOW YOUR WATER HEATER WORKS 
11 
MAINS PRESSURE 
The water heater is designed to operate at mains pressure by connecting directly to the mains water 
supply. If the mains supply pressure in your area exceeds that 
19, a pressure limiting 
valve must be fitted. The supply pressure should be greater than 350 kPa for true mains pressure 
operation to be achieved. The supply pressure should be greater than 140 kPa for the rated flow and 
performance of the gas booster to be achieved. 
 
GOING ON HOLIDAYS 
It is not necessary to switch off the electrical supply at the power outlet to the water heater if you are 
going away. However, if it is necessary to switch off the power to the water heater, refer to 
 on page 6. If the power to the water heater is switched off and there is a risk of 
freezing, then it is necessary to drain the gas booster (refer to 
on page 9)
