3 Using correct fill and make-up water

This chapter comprises general information to describe

the water in your heating system.

Observe the basic, system-specific requirements for

water quality in chapter 3.2 "Water quality".

3.1 Water description

In your heating system, water is used as the heat

transfer medium. Depending on its purpose, water is

given different descriptions.

–Heating water:

Water contained within your heating system.

–Fill water:

Water used for the first filling of your system before

commissioning.

–Make-up water:

Water used for the topping up of your system in case

of water losses.

Using correct fill and make-up water3

3.2 Water quality

Any water contains substances, e. g. Ca (HCO3)2

(Calcium hydrogen-carbonate), which may influence the

function of your heating system. These may lead to

corrosion, scaling or deposits.

Regularly check your water quality and, if necessary,

treat your fill and make-up water, to ensure that your

heating system permanently retains its economy,

function, operational reliability and energy efficiency.

Observe the following table regarding the appropriate

use and treatment of the fill and make-up water.

This table is an extract from the Code of Practice K8

"Water treatment for hot water heating systems" in the

Buderus sales catalogue.

CAUTION!

SYSTEM DAMAGE

through corrosion and scaling because of

fill and make-up water, which does not

comply with system-specific requirements.

Check with your local heating

contractor or your water supply

company regarding the Ca (HCO3)2

concentration (calcium hydrogen-

carbonate) in your area.

You should treat the fill and make-up

water, if it does not comply with system-

specific requirements. In such cases

contact your local heating engineer.

4 System start-up

This chapter explains, how you prepare the system for

operation and how to commission the control device and

the burner.

4.1 Making the system operational

You should check the following to prepare the system for

operation:

the system water pressure (see chapter 7.2

"Checking and correcting the water pressure",

page 13),

whether the fuel supply to the main fuel shut-off valve

is open,

whether the heating system emergency stop switch

is switched on.

Let your specialist show you where the fill valve is

located in the pipework of your system (return).

4.2 Commissioning the control device

and the burner

Start up your boiler via the control device (in this

example, Fig. 3: series 4000 control device). By

commissioning the control device, you also

automatically commission the burner. The burner can

then be started via the control device. For further details

in this connection, see the operating instructions of the

relevant control device or burner.

Switch the boiler water thermostat (Fig. 3, item 1) to

"AUT".

Set the On/Off switch (Fig. 3, item 2) to "I" (ON).

5 System shutdown

This chapter explains, how you shut down your boiler,

the control device and the burner. Furthermore, you will

find explanations as to how you can shut down your

system in an emergency.

Shut off the fuel supply at the main fuel shut-off valve.

5.1 Shutting down the control device and

the burner

Shut down your boiler via the control device (in this

example 3: series 4000 control device). The burner is

automatically shut down when the control device is shut

down.

Set the On/Off switch (Fig. 3, item 1) to "0" (OFF).

5.2 Shutting down the system in an

emergency

In other dangerous circumstances, isolate the main fuel

shut-off valve and the electrical power supply of the

system via the boiler room main fuse or the emergency

stop switch for the boiler room (see chapter 1.3 "Please

observe these safety instructions", page 4).

CAUTION!

SYSTEM DAMAGE

through frost.

The system can freeze up if it is not in use,

e.g. through a shut-down because of

fault(s).

Protect your system against frost

damage, where temperatures below

zero must be expected.

Drain the heating water at the drain

cock at the lowest point in the system,

using the KFE cock (boiler fill and drain

cock). To do this, open the air vent

valve at the highest point in the system.

USER NOTE

For further details in this connection, see

the operating instructions of the relevant

control device.

USER NOTE

Only in an emergency, switch off the

system via the boiler room fuse or

heating system emergency stop switch.
