External condensate pipework
The Worcester Greenstar Highflow CDi appliances have a
condensate pump rather than a syphonic condensate trap.
Rather than the condensate constantly dripping into the
discharge pipe, the condensate is collected in the pump
which releases it in 100ml quantities. This will help prevent
freezing occurring.
Wherever possible the condensate discharge pipework
should be routed and terminated internally. Should this not
be possible, and the only available route is external, the
following conditions should be observed:
•
The pipework length should be kept to a minimum and
the route as vertical as possible
•
Where pipework could be subjected to extreme cold or
wind chill, a weather proof insulation should be used.
Alternatively, the condensate pipework could be
increased to a minimum 32mm.
Compartment installation
The appliance may be installed in any room, although
par
ticular 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.
Air supply
1. The room in which the appliance is installed does not
require a dedicated 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:
Compartment installation
Position of appliance Min. unventilated clearance
In front 75mm*
Right side 100mm
Left side 100mm
Above flue elbow/casing 50mm
*75mm from an opening door. 600mm is required for servicing
Boiler location and clearances
This boiler is only suitable for installing internally within a
property at a suitable location on a fixed, rigid non-
combustible surface of at least the same size as the boiler
and capable of supporting the boiler weight.
Compartments: Follow the requirements of BS 6798 and
BS 5440 Part 2 and note:
•
Minimum clearances must be maintained
•
An access door is required to install, service and maintain
the boiler and any ancillary equipment
•
If fitting the boiler into an airing cupboard use a non-
combustible perforated material (maximum hole sizes of
13mm) to separate the boiler from the airing space.
Unvented compartment clearances
The diagram shows the minimum space required to install
and service the boiler inside an unvented compartment.
