3.3 Manifold suspension

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.
