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.

heater is satisfied.

6Maintenance

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:

*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.
