condensing boiler – inside story

Installing the Greenstar CDi

regular and 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 pipe work*

Key to components

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).

Compartment installation

The appliance may be installed in any room, although particular

attention is drawn to the requirements of the IEE regulations

applicable and in Scotland the electrical provisions with respect to

installation in a room containing a bath or shower.

1. The room in which the appliance is installed does not require a

purpose provided air vent.

2. If the appliance is installed in a cupboard or compartment with

dimensions that allow the minimum clearances shown in the siting

of appliance section above, then no ventilation is required.

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

Wall preparation

The drawing shows the CDi

Conventional wall mounting jig

which enables a simple and

straightforward method of attaching

the boiler to the wall surface.

After fixing the jig to the wall, the

appliance can be lifted onto the

jig and the union connections

tightened. The pipe work can be

routed behind the boiler without the

need for an additional wall spacing

frame.

Condensate disposal

All condensing boilers generate condensate discharge which needs

to be piped away from the appliance via a plastic pipe.

The amount of condensate generated depends on the efficiency

and operating status of the appliance. This can be up to 2 litres of

condensate water an hour.
