Thank you for your question, Carsbug! According to industry standards, the maximum allowable temperature of the water exiting from the valve is 120 degrees Fahrenheit. This temperature may vary in your local area. Although it is not possible to remove the Scaldguard feature nor is it recommended to remove the rotational limit stop, information on adjusting the temperature to the hottest setting can be found on page 7 of your maintenance and installation manual.
Best regards, Edward
