FEATURES OF YOUR INFINITY 20
n The Infinity 20 is one of the most advanced water heaters available. It supplies hot
water at the temperatures selected on either of the two electronic Remote Controls
supplied as standard with the appliance.
w The Master Control (larger control) can be fitted conveniently close to the shower
or bath area, and is used to override the Sub Control (smaller control) which is
normally fitted in the kitchen or other convenient area.
n The Transfer button on the Master Control enables you to select and lock the
preferred temperature for shower or bath water. When locked in, this selected
temperature cannot be overridden by the Sub Control.
n The Sub Control is used to select temperatures for kitchen, laundry etc.
n Temperatures selected at both Controls are retained in the system memory.
n The Infinity 20 never runs out. While the electricity, gas and water supplies are
connected, hot water is available for as long as the hot water tap is open.
n The burner lights automatically when the hot water tap is opened, and goes out
when the tap is closed.
n AGA’s 5 Star Energy Rating makes the Infinity 20 one of the most efficient water
heaters available.
n The Infinity 20 is an externally mounted, power flued appliance. It is very compact,
saving both floor and wall space.
