APPENDIX B: FACTORY MENU
Inappropriate changes to parameters in the Factory Menu (See Tables B-1 and B-2) could result
in a unit or system malfunction. For this reason, only a qualified technician who has in-depth
knowledge of the unit should make any changes to the parameters in this menu. The
parameters available allow the unit to be configured and set for proper operation.
The Factory Menu for boilers and water heaters are different from one another, so each is
illustrated separately in Figures B-1 and B-2.
To enter the Factory Menu, perform the following steps:
