WINTERIZING
NOTICE: If the SYSTEM 2000 Boiler may be exposed to freezing temperatures, such as a vacation home shut down
for the winter, then anti-freeze should be added. When a home is winterized by draining all domestic water piping, then
the SYSTEM 2000 Boiler must be protected. It is not recommended to drain the SYSTEM 2000 Boiler, because
introducing air into the boiler can cause rusting inside the boiler shell and also because the Energy Converter has a spiral
water passage that cannot be completely drained of water. When draining the domestic water piping system, be sure to
drain the domestic side of the plate heat exchanger. If the hydronic system will not be drained, then add enough anti-
freeze to protect the entire hydronic system including the boiler, piping, radiation, circulators, etc. If the hydronic system
will be drained, then add shut off valves to isolate the boiler and add anti-freeze to the boiler only, as follows. Drain water
from the boiler and then add anti-freeze to the boiler. Refill boiler with water and run boiler circulator through the bypass
to distribute antifreeze within boiler. Propylene Glycol in water will provide the following freeze protection: 30% down to
+8F, 40% to -8F, 50% to -27F. Energy Kinetics recommends using 30% anti-freeze to obtain the best boiler performance.
Use over 30% anti-freeze only if lower temperature freeze protection is mandatory.
Caution: Always keep the fuel supply valve shutoff if the burner is shut down for an extended period of time.
