7 .5 Installation
Installation of burners with FLUP in the horizontal posi-
tion, in the vertical position with the firing end pointing
downwards or at an angle with the firing end pointing
downwards.
Allow for adequate clearance between the radiant tubes
and the furnace wall to avoid local overheating, see
Technical Information SER-C.
Ensure that there is a recirculation gap
D1
between burn-
er and flame tube, e.g. SICAFLEX, (30 mm for ECOMAX
0 – 3 or 50 mm for ECOMAX 4 – 5). The deflector gap
V1
should equal 0.5 to 1.5 times the radiant tube diameter
X
.

7 .5 .1 Heat guard
During operation, the burner body and flue gas con-
nector or eductor can reach surface temperatures of
over 80°C. Do not insulate the burner, flue gas connec-
tor and eductor to prevent material overheating.
We recommend that warning signs and a contact guard
be fitted, for example made of perforated sheet metal.
