Installation & Operation Manual
1 General Information
The Lochinvar SSS series indirect water heater (FIG. 1-1) is
designed to generate domestic hot water in conjunction with
a hot water boiler using forced boiler water circulation. This
indirect water heater consists of a 444 Stainless Steel tank in
which a smooth 304 stainless steel coil is located. Boiler water
is pumped through the coil and heats the water in the tank.
This tank is not intended for use in pool heating applications
or for heating any fluid other than water. It is also not
intended for use in gravity hot water heating systems.

Installation & Operation Manual
2 Pre-installation
1. The installation must conform with the instructions
in this manual and all applicable local, state,
provincial, and national codes, laws, regulations, and
ordinances. Installations in Canada must conform to
B149.1 or B149.2 Installation Codes.
Locating the Tank
1. Figure 1-1 on page 4 shows the weights of all the tanks filled
with water. Make sure that the location chosen for the tank
is capable of supporting it.
2. Be certain the domestic water supply to the tank has
physical and chemical characteristics that fall within
the limits shown in Table 2A. Where questions exist
as to the composition of the water on the job, a
qualified water treatment expert should be consulted.
Failure to properly support the tank could
ƽ WARNING
result in property damage or personal injury.
2. Locate the system in a location where a leak in the tank, the
adjacent piping, or an open T & P valve will not damage the
surrounding structure. If the area around the desired tank
location is highly susceptible to water damage, install the
tank in a pan with a drain.
Water with characteristics outside the
CAUTION
limits shown in Table 2A may severely
shorten the life of the tank due to
corrosion. Damage to tanks in such
cases is not covered under warranty.
3. The tank may be located some distance from the boiler
provided the zone system is designed to provide the flow
called for in Table 3A - Pressure Drop Values, through
the coil. Also, the further the tank is from the boiler, the
longer the response of the boiler will be to a call from the
tank zone. Insulate piping between the boiler and the tank.
3. Read and understand all installation requirements in
this manual.
Table 2A
Water Chemistry Requirements
Recommended Clearances
Water used in the tank must have characteristics falling
within the following limits:
The installation location must provide adequate clearances for
servicing and proper operation of the water heater. A 12 inch
vertical clearance is recommended from the top of the water
heater. A zero clearance is allowed for the sides of the water
heater. However, boiler and servicing clearances must be figured
when locating the water heater.

3 Piping
DHW Prioritization
Boiler Side Piping
This piping system is designed to provide direct hot water
priority over the other zones in the heating system. When there
is a Domestic Hot Water (DHW) call for heat, the Knight control
will shut off the boiler circulator and activate the domestic hot
water circulator. Once the DHW demand is satisfied, the boiler
circulator will be readjusted as demand requires. The circulator
must be large enough to move the boiler water through the coils.
The recommended piping for a DHW priority system is depicted
in FIG. 3-3 on page 8.
Figures 3-1 thru 3-3 show typical boiler side piping for
several common situations. Regardless of which system is
used it is imperative that the flow rates called for in Table 3A
on page 6 are developed through the coil. This requires
properly sized piping and a properly sized pump.
The system shown in FIG’s 3-1 thru 3-3 are described below:
Zone with Circulator to Aquastat
This system is like the circulator zone system on a straight
heat job except that one of the zones goes to the tank instead
of radiation. As on any circulator zone system check valves
should be installed in each zone to prevent unwanted
circulation through zones which are not calling for heat.
Figure 3-1 on page 7 illustrates typical circulator zone
piping.
Multiple Tank Connections (Boiler Side)
Multiple tank installations must be done in the “reverse-return”
manner. The reason for this is to create the same pressure drop
(and therefore, the same flow) through the coil of each tank.
The boiler manifold piping must be sized so that each coil has
the flow rate called for in Table 3A below. For example, if two
tanks are to be manifolded together, the circulator and zone
piping common to both tanks must be capable of moving
16 GPM (2 x 8 GPM), see FIG. 3-4 on page 9.
Zone with Valve to Aquastat
As with the circulator zone system, this system is just like a
standard heating zone system except that one of the zones is
connected to the tank coil as shown in FIG. 3-2. The
circulator must be large enough to move boiler water
through the coil regardless of the flow rate required through
the heating zones.
Because the pressure drop through tank coils varies from size to
size, it is hard to predict the flow rate that will be developed
through each coil when two tanks of different sizes are placed in
the same manifold. For this reason it is best not to mix tanks of
two different sizes in the same zone if their recovery is critical.

3 Piping
Tank Piping with a “Temperature Limiting

Usually, the maximum temperature of the outlet water will stay
near the setting of the tank control. In some cases, however, hot
water usage patterns can cause the outlet water temperature to
rise significantly above the control setting.
Domestic Side Piping
Basic Domestic Piping
Figure 3-5 on page 12 shows typical domestic water piping for
a tank. All components except the control are provided by the
installer. The function of the components shown are as
follows:
The temperature of water going to the fixtures may be more
carefully controlled through the use of a thermostatic mixing
valve. This device blends a controlled amount of cold water
with the hot water leaving the tank so that water at a more

valve piping is illustrated in FIG.’s 3-1 thru 3-3.
c. Expansion Tank (required when a backflow preventer is
used) - This expansion tank absorbs the increased
volume caused by heating water. If a backflow
preventer is installed, this expansion tank is required
because the increased water volume will otherwise have
no place to go and the T & P valve will open.
An anti-scald mixing valve does not
eliminate the risk of scalding.

Set the tank thermostat as low as
practical.
Feel water before bathing or
showering.
Use an expansion tank designed for use on domestic
water systems.

If an expansion tank is used, do not put
any valves between the expansion tank
NOTICE
and tank inlet.
Multiple Tank Domestic Water Piping
d. Unions (optional) - Use to disconnect the tank in the
unlikely event that this is necessary.
Figure 3-4 illustrates the recommended method of piping the
domestic water side of several tanks together. All tanks are
piped in true parallel. Total domestic pipe lengths must be the
same from point of tank exit to the common “T” to ensure an
equal draw from each tank.
e. Drain (required) - Used to drain the tank for
inspection or servicing.
Each tank must have its own T&P valve. It is recommended that
each tank be equipped with its own isolation valves, unions, and
drains so that one tank may be removed from the system. If
local codes require a backflow preventer, check with the
appropriate authority to find out whether one backflow
preventer may be used for tanks or each tank must be equipped
with its own backflow preventer. If each tank must have its own
backflow preventer, each tank must also have its own expansion
tank. If a common backflow preventer is permitted, an
expansion tank must be sized to accommodate the expansion
volume of all tanks.

Domestic Water Piping for Distant Fixtures
NOTICE
NOTICE
In some cases the furthest fixture may be quite distant from the
tank. In such an installation the configuration shown in
FIG. 3-5 would result in an unacceptable delay before hot water
reaches these distant fixtures. Even if all the fixtures are
relatively close to the tank, the building owner may want hot
water at all fixtures as soon as they are opened.
valve with extended element.
The
recommended element length is 8 inches.
The Lochinvar SSS series water heaters will
absorb less than 200,000 Btu/hr when
domestic water outlet temperature is 210°F
and boiler water supply temperature is
240°F. Listed outputs are based on ASME
Section VIII Interpretation VIII-1-86-136.
Check with local codes for applicability.
A solution to this problem is that a pipe runs from the furthest
fixture on each branch back to the return of the tank. A small
bronze circulator is mounted in this line and is wired so as to
run continuously. A check valve in this line permits flow
towards the tank inlet only.
When no fixtures are drawing water, the bronze circulator
moves hot water from the tank to the end of the branch just
below the last fixture, then back to the inlet of the tank via the
return pipe. When a fixture is opened, hot water is already out
in the branch very close to the fixture and hot water appears at
it almost immediately. The check valve prevents cold water in
the tank’s inlet pipe from passing around the tank and heading
directly to the fixture.
Standard Installation

4. Make sure that each zone valve or circulator operates when,
and only when, its thermostat calls for heat. Let each zone
operate long enough to purge any remaining air from the

CAUTION
further. Leakage from the boiler piping
can result in severe damage to the boiler.
5. Set the indirect water heater to the desired temperature.
Because hot water presents a scald hazard, it is best to set the
thermostat at 120°F or lower and raise it only if necessary to
provide adequate hot water.
2. Many soldering fluxes contain Zinc Chloride which can
cause severe corrosion damage to stainless steel. After
completing all domestic water connections, flush the
indirect water heater thoroughly before leaving the
installation. This is particularly important if the indirect
water heater will be unused for an extended period of
time after installation. Flush the indirect water heater by
drawing at least three times its volume from the tank.
6. Re-enable the burner and allow the boiler to operate. Make
sure that the boiler shuts down when the indirect water
heater is satisfied.
3. Make sure that all electrical connections are made
correctly and that no exposed high voltage wiring is
present.
6 Maintenance
The Lochinvar SSS series indirect water heater is an extremely simple device and as such requires very little maintenance. There
are, however, several items which should be checked out on an annual or as needed basis to ensure a reliable supply of hot water:
*
The indirect water heater depends upon the boiler for a
source of heat and is therefore only as reliable as the boiler.
Make sure that the boiler is maintained in accordance with
the boiler manufacturer’s instructions.
*
On an annual basis, remove the black cover over the
hand hole and make sure the hand hole cover is
leak-tight.
*
*
Make sure that the rest of the boiler and domestic
water piping is free of leaks.
*
If a water treatment system is required to keep the water
chemistry within the parameters shown in Table 2A (see
Section 2 - Pre-Installation), make sure that this system is
properly maintained.
If there is an oil lubricated circulator in the system,
make sure it is lubricated as called for by the
circulator manufacturer.
