Introduction
The Halstead
Ace HE24
,
Ace HE30
and
Ace HE35
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) only. These
combination appliances provide the user with both central heating
(CH) and domestic hot water (DHW) on demand.
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 (29
3
⁄
4
in)), 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
, and twin flued,
C
53
, and special C

, applications, contact Halstead Boiler
Ltd Service Help Line: 08450 710780, for further details,
ONLY HALSTEAD APPROVED FLUE KITS OR
EXTENSIONS MAY BE USED WITH THESE APPLIANCES.
