Installing the Greenstar CDi
regular & system boiler series
The Greenstar CDi range is designed for connection to a
traditional heating and hot water system. The major
benefits of the Greenstar CDi regular or system boilers are:
The boiler is compatible with S and Y plan systems
The boiler comes supplied with a wall mounting bracket
WB5 cast aluminium/silicon heat cell
A syphonic condensate trap is pre-plumbed within
Built-in pump and expansion vessel*
No feed and expansion cistern in the loft space*
Less pipework*
Greenstar CDi boilers are exceptional for their number of
additional time saving installation features:
Built-in frost protection for boiler
Built-in fault finding diagnostics
Automatic gas pressure adjustment
Highly versatile multi-directional fluing system
Combined ignition and control board means fewer
connections
Pre-fabricated pipes allowing top exit from the boiler
A rigid 22mm compression gas connection eliminating
the need for pre-fabricating the gas pipe onto the
isolating valve
The large output range capability of the appliances
Siting of appliance
General
The appliances are not suitable for external installation.
The wall on which the boiler is to be mounted should be
capable of supporting an overall weight of approximately
50kg.
The wall does not require special protection. However, if
the appliance is to be fitted in a timber frame building the
guidelines laid down in BS 5440:Part 1:2000 and the gas
installer manual Chapter 11, “Gas in Timber Frame
Housing” should be adhered to.
The appliances may be installed into an airing cupboard
if required. Use a non-combustible perforated material
(max. hole sizes of 13mm) to separate the boiler from the
airing space.
Clearances
The minimum clearances shown opposite should be allowed
for installation and servicing, and are also the minimum
clearances required for installation into an unventilated
compartment (see below).
