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) 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 manufacturer’s 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
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.
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
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.
