Initial start−up, inspection and maintenance

Further details regarding the individual steps

Starting the heating system

Operating instructions, service instructions  control unit and burner

1. Check that the boiler room

ventilation aperture is open.

2. Check the inlet pressure of the

diaphragm expansion vessel.

If the inlet pressure of the

diaphragm expansion vessel is

lower than the static system

pressure, top up with enough

nitrogen to raise the inlet pressure

higher than the static system

pressure (0.1 to 0.2bar).

The static pressure corresponds to

the static head.

3. Open the check valves.

4. Top up your heating system with

water and vent it, until the

pressure is higher (0.1 to 0.2bar)

than the inlet pressure of the

diaphragm expansion vessel.

Permiss. operating pressure:3bar

5. Mark this pressure at pressure

gaugeA.

6. Return the check valves to their

operating position.

7. Open the oil or gas shut−off valves.
