Boiler with low water cut-off
(remote-mounted, field supplied)
A low water cut-off may be required by
local codes. If boiler is installed above
radiation level, a low water cut-off
device of approved type (field supplied)
must be installed in all instances at the
highest point of the piping system. Do
not
install an isolation valve between
boiler and low water cut-off.
Follow the installation
instructions of the low
water cut-off from the
manufacturer.
For low water cut-off wiring
information specific to your application,
refer to applicable wiring diagram on
the boiler enclosure panel.

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.
