Positioning - Schwank infraSchwank D 15U Technical Manual

Positioning

The radiant tube can be mounted with
 chains (links min. 4 mm)
 adjustable steel cable (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. 8 and 9 on pages 12 and 13.
Attention!
If you do not align the burner unit
correctly the device can be damaged.
