User maintenance procedures continued
Test low water cutoff
Test the low water cutoff periodically during the heating
season, following the low water cutoff manufacturer’s
instructions.
Clean vent termination and air
intake screens
1. Remove all lint and debris from both the boiler air
intake screen and the flue discharge screen.

the air intake or flue and lockout if the blockage is
excessive. It will signal by flashing the appropriate
indicator lights on the control board.
3. If removing the debris does not allow the boiler to
operate correctly afterwards, contact your qualified
service technician to inspect the boiler and vent/
air systems.
