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. 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.
