Introduction
The Halstead, Eden CBX , and Eden SBX range are, high
efficiency condensing, fully automatic, wall mounted gas
appliances suitable for either room sealed or opened flued
applications, for use with natural gas (G20), and LPG (G31). The
Eden CBX combination appliances provide the user with both
central heating (CH) and domestic hot water (DHW) on demand,
with DHW pre-heat feature. The
Eden SBX models are suitable
for a sealed central heating system, with the facility to heat and
control a hot water cylinder directly.
The appliances feature an attractive white stove enamelled casing,
with inset control panels. The flue systems are in white stove
enamel to give a clean attractive appearance to the installation.
A standard horizontal concentric air/flue duct terminal is
available, (maximum duct length of 755 mm (29in)), suitable for
room sealed applications. The duct assembly is connected to the
appliance via a turret, which can be orientated to provide different
horizontal duct directions. Extension ducts may be fitted in
accordance with and up to the maximum dimensions stated in
these instructions.
A vertical concentric outlet kit is also available for installations
where an outside wall is not accessible or where it is desired to fit
the duct 'through the roof'. Installation using the horizontal duct is
described in the main text of these instructions and additional
information is provided in the vertical outlet kit for the vertical
installation option. (Note: If the vertical outlet kit is to be used,
access to the roof is necessary).
Other flue kits are available for open flued (B
23
), split flued (C
53
),
and special (C
13
) applications, contact Halstead Boilers Ltd

ONLY HALSTEAD APPROVED FLUE KITS OR EXTENSIONS
MAY BE USED WITH THESE APPLIANCES.
