CAUTION

Small levels of chlorides and/or sulfur
presence in the combustion air or
fuel will negatively impact the heat
exchanger components. Any presence
of these contaminants will void the
warranty.

Some soaps used for leak testing are
corrosive to certain types of metals.
Rinse all piping thoroughly with
clean water after leak check has been
completed.

Install a strainer upstream of each boiler to ensure that no foreign matter
will have the opportunity to get inside the heat exchanger.

Low Water Cut Off

The Reliance boiler comes with an installed fl ow-switch type low water cut-off
(LWCO). The LWCO does not require fi eld piping or wiring. If the fl ow switch
does not sense fl ow, the boiler will shut down and an alarm condition will be
annunciated on the SOLA color screen display.
