Introduction

Please read these instructions and follow them carefully for a safe and economical use of your system boiler.

Important general instructions for use

This device should only be used for its intended purpose and in accordance with the regulations.

It is a requirement and in your own interest, and that of safety that this boiler must be installed by a CORGI registered installer, in accordance with the relevant requirements of the current Gas Safety (Installation and Use) Regulations, The Building Regulations, current I.E.E. Wiring Regulations and the relevant British Standard Codes of Practise.

The device may only be used in combination with the units, accessories and spare parts listed in the installation and maintenance instructions.

Other combinations of units, accessories and consumables are only to be used if they completely fulfil the specifications involved, and if system performance and safety are not affected in any way.

Subject to technical modifications

As a result of our policy of constant development, there may be small differences with respect to illustrations, functional steps and technical data.

Dear Customer,

Your Buderus 600 Series wall-mounted condensing gas boiler has been designed and built in accordance with state-of-the-art technological standards and the recognised safety rules. Special focus has been placed on operator convenience in this respect.

Carefully read the safety instructions and operating manual to ensure safe, economic and ecologically beneficial use of the unit.

Due to the high efficiency of the boiler a plume of water vapour may form at the terminal during operation. This is normal.

1 Safety precautions

ADANGER!

If you smell gas:

1. No naked flames! Do not smoke!
2. Avoid sparks!

Do not operate electrical switches.

Do not use the telephone, plug-in devices of any kind or the doorbell!

1. Shut off the main gas supply!
2. Open windows and doors!
3. Warn building occupants and evacuate the building!
4. Call TRANSCO (under 'GAS' in the telephone directory) from outside the building!

INOTE

In the event of any other type of incident, shut off the main gas supply and electric supply to the appliance and seek assistance from a CORGI registered engineer.

2 Installation area / boiler room

ADANGER!

The air intake and outlet openings must not be reduced in size or closed.

ADANGER!

Do not store or use inflammable materials or liquids near the heating boiler.

INOTE

To prevent the boiler from being damaged, care must be taken not to contaminate the combustion air with halogenated hydrocarbons (e. g. contained in aerosol sprays, solvents, detergents, paints, and adhesives), or with high quantities of dust. The room in which the boiler is installed must be frost-proof and be well ventilated.

3 Working in the heating system

ADANGER!

Only a CORGI registered Engineer is to be entrusted with the installation of this boiler, the gas supply and the flue connection.

Commissioning, Servicing and any Repairs must be carried out by a competent person i.e.: a CORGI Registered Engineer.

All CORGI Registered Installers carry a CORGI identification card and have a registration number. Both should be recorded in your boiler logbook. You can check your installer/Engineer is registered by telephoning 01256 372300 or by writing to:

CORGI, 1 Elmwood, Chineham Business Park, Crockford Lane, Basingstoke. RG24 8WG

4 Functions of the system and operating instructions

The installer should familiarize the user with the functions and operation of the heating system and ensure that a complete set of technical documentation is supplied.

5 Maintenance intervals

For optimum, long-term reliable functioning of the heating boiler, and in order to be able to claim under the terms of the manufacturer's warranty, the heating boiler must be inspected and maintained at least once a year (under normal operating conditions) by an officially recognized installation and service engineer. The term "normal operating conditions" means that the heating boiler is used to provide central heating and/or hot water to no more than one single-family dwelling.

In all other cases, the heating boiler must be inspected and maintained by an officially recognised installation service engineer every 2,500 burner operating hours.

6 Initial start-up

6.1 Preparing for operation

Please note also the operating instructions supplied with the control unit.

6.1.1 Check water pressure

• Open the control panel cover.
• Check the water pressure (fig. 1, item 1). Optimum filling pressure is 1.0 to 1.2 bar, max. water pressure is 1.5 bar.

If pressure is below 1.0 bar, proceed as described in "Topping up the heating system", otherwise continue as described in Section 6.1.3 "Temperature-setting adjustments".

Fig. 1 Pressure display

Topping up the heating system

AWARNING!

The wall-mounted condensing gas boiler must not be activated at this stage.

The system should be filled with untreated mains water.

- Set three-way valve to the middle setting (applicable for 24C only). This is done by pushing the lever on the three-way valve (fig. 2) with a screwdriver to the middle setting.

Fig. 2 Three-way valve

- If necessary open the CH flow and CH return maintenance valves (fig. 3, item 1 and 2).

Fig. 3 Maintenance shutoff valves

● Connect temporary hose (fig. 4).
- Open both stop valves.

Fig. 4 Connecting temporary hose

• Fill the system to a pressure of 1.0 to 1.2 bar (fig. 5, item 1). Max. water pressure is 1.5 bar.
  ● Shut both stop valves and disconnect the filling loop.
• Fill the system to a pressure of 1.0 to 1.2 bar (fig. 5, item 1). Max. water pressure is 1.5 bar.
  ● Shut both stop valves and disconnect the filling loop.

6.1.2 Purging the heating-water circuit

● Unscrew the four screws at the top and bottom of the ventilation cover (fig. 6, item 1) and remove the ventilation cover.

Fig. 6 Remove ventilation cover

• Open the cap on the automatic vent unit (fig. 7) by one turn to allow any residual air to escape.
• If the air purging operation causes the pressure to drop, top up with water.
  ● Refit the ventilation cover.
• Remove the hose from the filling and draining valve, unscrew the hose spigot and screw the cover cap back on.

INOTE

If there are frequent water losses, have the system examined and repaired by a CORGI registered installer.

Have the inhibitor concentration checked every year.

6.1.3 Temperature-setting adjustments

• Set flow temperature at the control unit (fig. 8, item 6) (see table 1).
• Set hot-water temperature for 600 - 24 C with integrated hot-water supply at knob (fig. 8, item 3) (see table 2).

For energy saving (no heat-retention function) move knob (fig. 8, item 3) to cold-start-setting "1". Set outlet temperature, at the same time, to 60 °C.

• Set hot-water temperature for 600 Series with external tank at control unit (fig. 8, item 3) using table 3.
• Adjust room temperature to maximum setting at the control unit.
• Open the gas service valve by pushing in and turning anticlockwise into a vertical position (fig. 8, item 4).
• Push the mains power switch (fig. 8, item 1) to "I". The boiler runs through the start-up programme and the burner is ignited after approx. 30 seconds.
• Adjust room temperature to desired setting at the control unit.
