!

Note   For both horizontal and inclined
mounting the fan assembly must be perfectly
vertical with the fan outlet facing upwards.

For unflued heaters a fan baffle must be
attached to the fan outlet.

For herringbone heaters refer to the relevant
information leaflet (GB/HB/134/0402).

A herringbone system allows several Vision
Compact heaters to be operated by one
combustion fan. This has the benefit of only
one building penetration being required
when fluing the products of combustion.

Ambi-Rad Limited cannot be responsible for
ensuring that all site safety procedures are
adhered to during assembly and installation.
Sole liability rests with the installer.

Attachment to the heater support lugs
should be made by either a ‘speed link’, D
shackle, nut bolt and large washers, 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 not
being available, 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
consultant / architect / owner of the 
building.

The recommended minimum and preferred
mounting heights, along with the 
recommended clearance to combustibles for
the Vision Compact range of heaters is
