Installation & Operation Manual
6 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.
