The Service Screen allows the integrated control to override all other heat demands and operate Valve 1 and Valve 2 at high fi re and
low fi re conditions. To place the boiler into Service Mode, press the START button. As specifi ed above the integrated control will
override all other heat demands, however, all safeties will be active. If no buttons are pressed, the integrated control will automatically
revert back to its original status after the “Remaining time in Servicer” counter expires.
Once the boiler has been placed into Service Mode it will light and modulate to low fi re. At any time after that point there are two (2)
ways to adjust the fi ring rate. The fi rst way is by pressing one of the six (6) preset buttons. The second way is by manually adjusting
the fi ring percentage using the “+” and “-“ buttons. When Service Mode is no longer needed press the STOP button to return to
normal operation.
