Positioning

The radiant tube can be mounted with
 chains [links min. 4 mm]
 adjustable steel wire suspension system
[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.
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. 12 and 13 on pages 17 and 18.
Attention!
If you do not align the burner kit
correctly material damage and
destruction of the heater may occur.
