GENERAL SAFETY INSTRUCTIONS FOR GAS APPLIANCES

General remarks 

• 

 The end user is only allowed to carry out the basic set-up operations mentioned in 

"Water heater Setup Guide" on page 8, after he has received all relevant instructions 

from the installer. Any other set-up must be carried out by an approved installer. 

• 

If the end user misuses the installer code to access installer-specific parameters and 

makes changes that cause a system failure, any warranty claim will be void.

• 

 To get additional information on how to use the ACVMax interface, refer to the installer-

specific settings and the detailed error codes, in the Installer's Handbook available at 

www.acv.com.
