Zone Control:
ZONE CONTROL BY VALVE:
The EK-Pak is designed to provide from one to four zones for
the heating system and domestic hot water. Energy Kinetics recommends and can supply two
wire, full port, 24-volt zone valves for control of each heating zone. Four wire zone valves with
end switches can also be used. Energy Kinetics recommends using four wire zone valves with
end switches for control of air handler zones. Refer to air handler wiring diagrams for details.
EXPANSION TANK SIZING:
The type and size of expansion tank depends on the total
system water volume.
NOTICE:
Sizing must consider
cold start
and
hot operation
.
Hot Water Storage Tank:
The hot water piping schematic indicates a typical arrangement of the domestic hot water
system. The tank may be located adjacent to or in any other convenient location. If greater
than 10 feet away, use ¾” lines and a manual air vent on a high return. Insulation of water
lines between the storage tank and EK-Pak and on the hot water supply to the house is
recommended for best fuel efficiency. Energy Kinetics supplied storage tanks come complete
with high-density foam insulation, a properly located aquastat, a temperature/pressure relief
valve, and a specially designed dip tube.
DANGER:
Hot water temperature over 125F can cause severe burns instantly or
death by scalding.
Children, disabled, and elderly are at the highest risk of
being scalded. Test water temperature before bathing or showering.
Temperature limiting, anti-scald mixing valves are available and recommended.
Hot water storage tank aquastat does not limit the maximum delivered
water temperature.
The plate heat exchanger will always provide water that is
hotter than 125F into the hot water storage tank where it will mix with the water
in the storage tank. The hot water storage tank can deliver water hotter than
125F depending on the degree of tank temperature stratification. If codes place
limits on maximum delivered water temperature, an anti-scald mixing valve
MUST
be installed on hot water tank outlet.
Plate Heat Exchanger:
NOTICE:
The plate heat exchanger is piped at the factory and its location and orientation
should not be altered without consulting with Energy Kinetics.
Pipe domestic water to the connections as marked on the plate heat exchanger. When
ordering a replacement, order the part number shown in the Assembly Drawing.
WARNING:
The single wall plate heat exchanger complies with 1990 N.S.P.C. provided that both of the following
are true:
A) The heating module water (including additives) is practically non-toxic, having a toxicity
rating or class of 1 as listed in Clinical Toxicology of Commercial Products, 5
th
Edition; and
B) The pressure of the heating module water is limited to a max of 30 psig by an approved
safety or relief valve.
