A low water cut-off may be required by local codes. Do
not install an isolation valve between boiler and low water
cut-off.
For low water cut-off wiring information specific to your
application, refer to applicable wiring diagram (see page 47).
Under certain climatic conditions some building materials
may be affected by flue products expelled in close
proximity to unprotected surfaces. Sealing or shielding of
the exposed surfaces with a corrosion resistant material
(e.g. aluminum sheeting) may be required to prevent
staining or deterioration. The protective material should
be attached and sealed (if necessary) to the building
before attaching the vent termination. It is strongly
recommended to install the vent termination on the
leeward side of the building.
Follow the installation instructions of the
low water cut-off from the manufacturer.
