The Greenstar Si condensing
combi boiler – inside story
Installing the
Greenstar Si series
All combi boilers require less installation time than a conventional
boiler, for these reasons:
1. All the major components, including the pump, are
contained within the boiler casing and do not need
to be fitted separately.
2. The boiler comes pre-wired and pre-plumbed.
3. There is no need to install a hot water cylinder.
4. There is no need to install a storage tank in the roof space.
5. There is less pipework.
However, the Si Junior series is exceptional for its number of
additional time-saving installation features:
●
One man lift
●
Automatic gas pressure adjustment
●
Unique and highly versatile multi-directional fluing system
●
Combined ignition and control board means less connections
●
Optional plug in filling loop
●
Optional plug in timers

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 40 kg.
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.
See page 11 for details.
Clearances
The following clearances should be allowed for installation
and servicing.
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 following minimum clearances, then no
ventilation is required:
