Startup and maintenance
*
Ensure that the boiler and solar water piping are 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.
*
Make sure that the heat source is maintained in accordance
with the 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.
Annual service by a qualified service technician
should include the following:
Any procedure required by local codes.
Verify system pressure. Air venting procedure may require
adding water to bring boiler system up to pressure, typically
12 psig minimum.
Manually operate T&P relief valve at least once a year.
This will release some hot water.
WARNING
Before operating a T&P relief valve, make
sure no one is in front of or around the T&P
relief valve discharge piping. Hot discharge
water can cause severe personal injury or
substantial property damage.
DANGER
Plugging the T&P relief valve or discharge
piping can cause excessive pressure in the
water heater, resulting in severe personal
injury, death, or substantial property
damage.
Move operating lever to open position for a few seconds
and then move it back, allowing it to snap closed. After the
T&P relief valve is operated, if it continues to release water,
close the cold water inlet to the water heater immediately.
Follow the draining instructions, and replace the T&P
relief valve. If the T&P relief valve weeps periodically, it may
be due to thermal expansion. Do not plug the T&P relief
valve or discharge piping. In this case, ensure that the
expansion tank is properly sized and charged to the
appropriate
pressure.
Installation & Operation Manual
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 heat source and
solar piping can result in severe damage to
the system.
2. Many soldering fluxes contain Zinc Chloride which
can cause severe corrosion damage to stainless steel. After
completing all domestic water connections, flush the
Strato-Therm+ tank and indirect coil thoroughly before
leaving the installation. This is particularly important if the
Strato-Therm+ will be unused for an extended period of
time after installation. Flush the storage tank by drawing at
least three times its volume from the tank.
3. 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.
Refer to the heat source and solar Installation and Operation
Manuals for additional start-up information.

Maintenance Schedule
The Lochinvar Strato-Therm+ solar tank is an extremely simple
device and as such requires very little maintenance. There are,
however, several items which should be inspected on an annual
or as needed basis to ensure a reliable supply of hot water:
Verify that expansion tank pressure is equal to system
pressure.
