The manifold should be supported
by chain, stainless steel flexible wire,
or other flexible means from the roof
structure to allow movement caused
by thermal expansion. For maximum
support centres see figure 5.
Flexible couplers (supplied by
Ambi-Rad) must be inserted within
the manifold system to allow linear
expansion to take place and prevent
stress and strain on the system.
Note The manifold must be supported
either side of the flexible coupler.
Where the HB heaters are to be
inclined/wall mounted, the manifold
must be installed at the same height as
the centre of the emitter tube. For
typical wall mounting bracket
arrangement see AR installation
manual (GB/ARE(E)079/0501).

3.4 Condensate trap
A condensate trap assembly must be
provided at the end of the manifold
system before the hot gas vacuum fan.
(See figure 8a)
The minimum depth of the condensate
collecting chamber shall be 305mm
(12in) and the minimum depth of the
condensate drain pipe 'U' trap shall
be 457mm (18in) deep.
The end cap of the collecting chamber
to be fitted with a flush flanged tank
connector. Any protrusion to be
removed leaving the inside flush
with end cap (see figure 9). The end cap
to be sealed with silicon jointing
compound and pop riveted in position.
All condensate drains from the flue
collecting chamber to the disposal point
shall be corrosion-resistant material of not
less than 22mm internal diameter. Copper or

copper based alloy shall not be used for
condensation drains. See reference
BS 6896:1991. Condensate drain pipes must
be protected against the effects of freezing.
