instructions for british gas 330 boiler?

Without sarcasm, press top dimpled part of front cover, water temp from boiler is adjusted there (+/-). Also, there should be a thermostat on your hot water tank ('stuck' or tied to the tank) that sets the tepmerature of the water in the tank (at least 50 deg. needed). The maximum this can be set to is the same as the boiler. Hope this helps.
