The water heater must have electrical supply voltage of 230
Mechanical ventilation
The supply of air by mechanical means shall be by mechanical
inlet with natural of mechanical extractions, mechanical
extract with natural inlet must not be used. The minimum flow
rates with mechanical ventilation are as follows:
Inlet Air (Combustion ventilation) - 1.1 m /s per 1000 kW total
3
rated heat input.
Extract air (ventilation) - 0.45 m /s per 1000 kW total rated heat
3
input. Further details regarding air supply are given in BS 6644.
according to the current national and local demands, norms

must never fall below 18 mbar
.
With a lower gas pressure it is possible that the water heater
will not run at 100% capacity. At the same time the water heater
can be more prone to failures.
Adjust the burner pressure with a supply pressure of 20 mbar
before the water heater.
according to the current national and local demands, norms
and standards.
