Positioning

The radiant tube can be mounted with
 chain links [welded] min. 4 mm strong
 adjustable steel cable 3 mm strong
[Schwank accessories]
If you chose chains please use bolts with lock nuts
for fixing the chain to the suspension bracket.
The radiant tube has to be fixed by
vertical chains etc. to the roof or to
supporting devices.
Chains and steel cables have to be
fixed in vertical direction or slightly
diagonally outwards above the fixing
points of the suspension brackets to the
roof or to supporting devices. Fixing of
the suspension cables or chains
diagonally inwards to the centre of the
heater is not permitted [see Fig 5].
Please note that the radiant tube being
in operation expands several
centimetres because of thermal
expansion. Avoid therefore inflexible
suspension.
Do not use fixing elements like open
hooks etc.
When fastening to trapezoidal sheet
roofs, make sure that the maximum
surface load is not exceeded, if
necessary. The load must be distributed
over a larger area by means of a
substructure.
Hang the heater in balance. We recommend the
use of turnbuckles or adjustable steel cable grips
for ease of adjustment and balance.
Fixing points for chains or steel cables on the heater
are shown in Fig 16, 17, 18 and 19 on pages 21 and
22.
