Start-up Information

Initial start-up

Initial start-up must be performed by qualified personnel;
values and calibrations specified in the Technical Data
section on page 38 in this manual are to be recorded
at this time.

Instructing the system user

The installer of the system is responsible to ensure the
system operator/ultimate owner is made familiar with
the functioning of the system, its activation, and its
shut-down. The following topics must be covered:
H Proper system operation sequence.
H Explain the equipment as well as the need for
combustion air.
H Demonstrate an emergency shut-down,
what to do and what not.
H Explain that there is no substitute for proper
maintenance to help ensure safe operation.
H Annual inspection is recommended.

Shut-down

Deactivate main power to heating boiler(s) and burner(s)
if burners have separate power supply, and deactivate
power to circulating pump(s). Close all boiler isolation
valve(s) as well as all fuel supply valve(s).

Extended shut-down periods

If after the heating period the boiler is shut down for
the summer months (no domestic hot water production),
the boiler should be properly cleaned, incl. combustion
chamber, flue gas passageways, and, as necessary,
vent pipe connector, to avoid corrosion.
The boiler and system must remain filled with water.
Do not drain boiler or heating system.
