Siting of appliance

All combi boilers require less installation time than a conventional boiler, for these reasons:

• All the major components, including the pump, are contained within the boiler casing and do not need to be fitted separately

• The boiler comes pre-wired and pre-plumbed

• There is no need to install a hot water cylinder

• There is no need to install a storage tank in the roof space

• There is less pipework in the heating system

• One man lift (Greenstar i Junior and Greenstar Si)

• The boiler comes supplied with a wall mounting bracket (Greenstar CDi) or a wall mounting jig (Greenstar i Junior and Greenstar Si)

• Automatic gas pressure adjustment

• Highly versatile multi-directional fluing system

• Combined ignition and control board means less connections

• Plug-in filling link (optional on Greenstar i Junior and Greenstar Si)

• Optional plug-in timers

• Built-in frost protection

• Vertical pre-piping assembly accessory providing pre-formed copper pipe lengths and earth bonding strip (Greenstar i Junior and Greenstar Si only)

The appliances are only suitable for installing internally within a property at a suitable location onto a fixed, rigid surface at least the same size as the appliance and capable of supporting its weight.

No surface protection is required against heat transfer from the boiler. However, if the appliance is to be fitted in a timber frame building the guidelines laid down in BS 5440:Part 1 and the CORGI publication “Gas Installations in Timber Frame Buildings” 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 below should be allowed for installation and servicing. Compartment ventilation would be required at these clearances.
