Start-up and Check-out
1. Make sure the system is free of leaks and that air is
purged from the system.
CAUTION
Fix any leaks found before proceeding
further. Leakage from the boiler piping
can result in severe damage to the boiler.
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.
3. Make sure that all electrical connections are made
correctly and that no exposed high voltage wiring is
present.
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
system.
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.
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.

Maintenance
* 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 there is an oil lubricated circulator in the system,
make sure it is lubricated as called for by the
circulator manufacturer.
* 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.
* 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.
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:
