Installation requirements

Installation of the Greenstar CDi series must be in accordance with

the relevant requirements of the Gas Safety (Installation Use)

Regulations (as amended), current IEE Wiring Regulations, local

Building Regulations, Building Standards (Scotland) (Consolidation)

regulations and bylaws of the local Water company and Health and

Safety Document No. 635 (Electricity at Work Regulations 1989).

It should be in accordance with the relevant recommendations of the

following British Standards:

BS 6798; BS 5449; BS 5546:1; BS 5440:1; BS 5440:2;

BS 6891.

Gas Safety (Installation and Use) Regulations. All gas appliances

must be installed by a CORGI registered person in accordance with

the above regulations. Failure to install appliances correctly could

lead to prosecution.

The manufacturers notes must not be taken in any way as overriding

statutory regulations.

Sealed primary systems

The appliance is fitted with a manual reset high limit thermostat and

is suitable for use with a sealed primary system.

The system should be installed in compliance with the requirements

of BS 5449: Part1. The system must be fitted with a spring loaded

safety valve set to operate at 3bar (45 psi) and the pipe connections

made through the system must be capable of sustaining a pressure

of up to 3bar.

Manual air vents should be fitted at any high points in the system.

The following is a list of major items which must be fitted to the

system:

1. Safety valve – 3bar

2. Pressure gauge – 0 - 4bar

3. Expansion vessel

4. Automatic air vent

Typical fully pumped sealed system

System filling and make-up

To comply with the Water Authority requirements, the system

should be filled via a temporary hose connection to the mains cold

water supply, with a double check valve assembly and test point

fitted to the mains water side of a temporary circuit. Alternatively,

for the Greenstar CDi boilers, the plug in filling loop option (part

number 7 716 192 281, see page 22 for photograph), simply

connects between the cold main connection and the heating

return circuit on the wall mounting jig.

Valves and joints

It is very important that all valves and joints are able to sustain a

working pressure of up to 3bar (45psi). Particular care should be

exercised when fitting radiator valves and only those of high quality

to BS 2767:10 should be used. All other valves and fittings should

comply with BS 1010.

Loss of water pressure from a sealed system will require

continuous recharging with fresh water and consequential

introduction of air. Air is highly corrosive and will considerably

reduce life expectancy of radiators, pumps etc.

30CDi System diverter valve kit

The 30CDi System boiler can be adapted to house an in-built

diverting valve. The optional valve motor kit allows the user to

control the supply of heat to the hot water cylinder from the boiler.

Plastic pipe work

The use of plastic pipe work is acceptable. However, some plastics

are permeable to oxygen and must be avoided. Only pipe work with

a polymeric barrier should be used. Please note that the first

600mm of pipe work connected to the boiler must be of copper or

steel.
