piping systems shall be equipped with ow control
valves or other automatic means to prevent gravity
circulation of the boiler water during the cooling cycle.
9. The boiler is not provided with a drain valve directly on
the boiler. A drain valve should be installed near the
system return (water inlet) connection to the boiler and
piped to a drain.
10. Before installing a Caliber boiler into a hydronic loop, be
sure that the system piping and any other components
of the system are clean and free of debris and any
foreign matter. The hydronic system is completely
ushed prior to installing the boiler itself. 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 Caliber boiler comes with an installed ow-switch type
low water cut-o (LWCO). The LWCO does not require eld
piping or wiring. If the ow switch does not sense ow,
the boiler will shut down and an alarm condition will be
annunciated on the SOLA color screen display.
