1.1 Health and Safety
AmbiRad heaters must be installed in
accordance with the relevant provisions of the
Gas Safety (Installations and Use) Regulations
1998. Due account should also be taken of any
obligations arising from the Health and Safety
at Works Act 1974 or relevant codes of
practice. In addition the installation must be
carried out in accordance with the current IEE
wiring regulations (BS 7671), BS 6896:2005
(Industrial & Commercial) and any other
relevant British Standards and Codes of
Practice by a qualified installer. Isolate all
electrical supplies to the heater & controller
before proceeding.
For your own safety we recommend the use of
safety boots and leather faced gloves when
handling sharp or heavy items. The use of
protective eye wear is also recommended.
1.2 Model Definitions
VSOUT = AmbiRad Vision U Tube Unitary
heater with painted induced burner, ID Fan,
aluminised steel reflectors, end caps,
insulation, tube over shields, painted canopies
and optional end covers.
VSOUH = AmbiRad Vision U Tube
Herringbone heater with painted induced
burner, Damper, aluminised steel reflectors,
end caps, insulation, tube over shields, painted
canopies and optional end covers.
VSXO = AmbiRad Vision High efficiency
U Tube heater with forced burner, recuperative
heat exchanger, aluminised steel reflectors,
end caps, insulation, tube over shields, painted
canopies and optional end covers.
1.3 Heater Suspension
See fig 3.b. Attachment to the heater
support lugs should be made by a ‘speed
link’, D shackle or in the case of drop rods, a
closed formed hook. The hanging attachments
to overhead steelwork etc. must be purpose
made to good sound engineering practice or of
a proprietary type fixing. They must be
adequately fixed and designed to carry the
whole weight of the heater. In the event of
suitable roof steelwork being unavailable,
additional steelwork should be fitted to enable
vertical hangers to be used for suspending the
heaters.
If there are any doubts as to the strength or
suitability of roof steelwork to which heaters are
to be suspended, please refer to a Consultant,
Architect or owner of the building. The
minimum mounting heights for AmbiRad heaters
are given in the table below.
1.4 Wall Mounting
These radiant tube heaters can be wall mounted
using the appropriate bracket (AmbiRad part no
WMB-13-22-38).
When using the wall mounting brackets the
heater must be inclined at an angle between 30°
and 35°.

Where chain supports have an
angle of inclination greater
than 15° an equal and opposite
support is recommended.
Vertical suspension chain ideal.
Where supports are inclined,
maximum recommended angle
of inclination is 15°.
Shackle method of
attachment. Pin must
be tightened by pliers.

note. hook or eyebolt must
be closed tight.

1.5 Herringbone Systems (VSOUH).
The manifold system should be arranged to fall
slightly in the direction of the vacuum fan. This
ensures that any condensation formed in the
manifold on cold start and cool down is not
trapped or allowed to drain back into the heater
unit. This allows condensate to flow towards
the condensate trap located at the vacuum fan
end of the manifold system. (See figure 4a
below for condensate trap arrangement).
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
100mm diameter manifold the maximum
distance between supports is 2.4m and 3.0m
for 150mm diameter.
Flexible couplers (supplied by AmbiRad) must
be inserted within the manifold system to allow
linear expansion to take place and prevent
stress and strain on the system.
The exhaust flue should be adequately
supported from the building structure and
installed in accordance with the British
Standard Code of Practice BS 5440: Part
1:2000 – Installation and maintenance of flues
and ventilation for gas appliances of rated input
not exceeding 70kW net (1st, 2nd and 3rd
family gases)
A condensate trap assembly must be provided
at the end of the manifold system before the
hot gas vacuum fan.
The minimum depth of the condensate
collecting chamber shall be 305mm and the
minimum depth of the condensate drain pipe
‘U’ trap shall be 457mm 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.
The end cap should 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 6896:2005.
Condensate drain pipes must be protected
against the effects of freezing.
The Type ‘0’ and Type ‘2’ vacuum fans have
bottom horizontal discharge with rectangular
connections (flanged on the type 0) and must be
mounted in that position by means of the fan
support stool onto a suitable platform or
brackets fixed to the building structure.
For details of the fan outlet fixing holes see
below.

Where a conventional flue is to be installed,
AmbiRad supply an aluminium transformation
piece to which a 150mm (6ins) diameter flue
must be attached.
The length of flue which may be connected to
the fan outlet must be adequately supported
from the building structure.

Dos Don’ts
Check for corrosive industrial process in
proposed building - e.g. cleaning, electroplating,
printers using sugar powder etc.
Install system with extra 90° bends without asking
AmbiRad if the system will operate correctly.
Drain all flue ducts and seal all joints. Install flue with vertical rise without firstly fitting a
drain point at it’s lowest level.
Secure joints with pop rivets as well as sealing
compound (refer to assembly instructions). Fit fan with outlet vertical or with top horizontal
discharge.
Fit drain traps before and after fans (see figs 4). Fit damper upside down or on it’s side.
Fit expansion joints before fan and at
intermediate points on the herringbone system. Fit damper wrong way round. (see fig20)
Run drains in galvanised steel or plastic pipes.
Follow guide to combined flue heating system.
Check design pressure drop. Run drains in copper or mild steel pipework.
