3. After ensuring there are no leaks within the system, flush the
system to clear any soldering residue. Many soldering fluxes contain
Zinc Chloride, which can
corrode stainless steel.
Draw at least three times
the volume of the water
heater to properly flush the
system.
4. Initiate a call for hot
water. Ensure each zone
valve or circulator operates
only when its thermostat
calls for heat. Purge each
zone of air to ensure proper
operation.
5. Set the water heater to
the desired temperature.
Boiler high limit should
be set at least 20
o
F
higher than the heater
temperature. Set the low
limit of the boiler control at
the minimum setting - this
will call the burner on only
to satisfy the tank control.
A water heater temperature setting of 120
o
F is recommended.
However, a lower temperature setting may be required to comply with
local and state codes for normal operation. The differential should
be set at 10 to 15
o
F. Installation conditions may require a higher or
lower temperature setting. A mixing valve in conjunction with a high
temperature setting may be used for high demand applications (spas,
hot tubs, whirlpools).
6. When the system is completely flushed, purged of air, and the
temperature is set, turn on the boiler. Observe operation. Ensure the
boiler shuts down after the indirect water heater set point is satisfied.
1. Fill the water heater by opening the cold water shut-off valve. Make
certain the field installed drain valve is completely closed. Purge air
from the system by opening a hot water outlet at a fixture in a kitchen
or bathroom. When water flows freely from the outlet, the system is
purged.
Part 5 - Start-Up and Operation
When filling the water heater, open a hot water tap to release air in
the tank and piping to ensure proper water heater operation. Failure
to ensure the water heater is full before turning on the system will
result in damage to the water heater, and could result in property
damage. Such damages ARE NOT covered by warranty.
2. Check the system for leaks.
Fix any leaks before continuing the installation. Failure to do so could
result in property damage or personal injury.
Risk of scald injury increases as you increase water temperature.
