6.4.1
Remove the packaging/protection from the Radiant Tubes (2 long tubes and 2 short tubes) and ensure that
they are clear internally. Join one long tube and one short tube together using a Torctite Coupling. Ensure that
the tubes engage fully into the Torctite Coupling (up to the stop) and that the welded seam of the tubes is in line
from one tube to the other and that the Torctite Coupling clamp is positioned adjacent to the weld seam.
Tighten the nuts of the Torctite Coupling to secure it to the tubes taking care to support the tubes to maintain
the axis of the tube in a straight line. Repeat the procedure above to join the remaining long and short tubes.
Place the Radiant Tube assemblies on tressels providing 150mm minimum clearance above the floor with the
Torctite Coupling clamp underneath and the weld seam of the tubes in contact with the hanger bracket (see
6.4.3 below) i.e. facing away from the reflector. Space the tube assemblies 305mm apart with the ends of the
short tubes (and Torctite Couplings) in line.
NOTE: Tighten the Torctite Coupling screws alternately whilst continually checking for slackness of the joint.
IMPORTANT
: Failure to assemble the Radiant tubes with their welded seam facing away from the reflector will
void the manufactures warranty.
6.4.2
Assemble the U Bend to the short Radiant Tubes, ensuring that the U Bend engages fully. Drill one Ø5.5mm
hole through the U Bend and Radiant Tube in the upper surface of each leg of the U bend at a distance midway
along the swaged portion of the U bend as shown in Fig 22. Rivet the U Bend to the Radiant Tube assemblies
using the two Ø5 x 10 rivets provided (fastenings pack).

6.4.3
Assemble the four Hanger Brackets to the Radiant Tubes using two U bolts per bracket (from fastenings pack)
and position along the Radiant Tubes as shown in Fig 21. Tighten the nuts sufficiently to retain the hanger
brackets. Do not over tighten.
6.4.4
Place one Torctite Coupling over the open end of the RH Radiant Tube (viewed from the open end of the tubes)
ensuring that it engages fully, up to the stop. Assemble the Control Box to the RH Radiant Tube ensuring that it
engages fully into the Torctite Coupling (up to the stop) and is positioned vertically with the door latch
uppermost (see Fig 9). Tighten the nuts of the Torctite Coupling to secure the Control Box to the Radiant Tube,
taking care to support the Control Box in line with the axis of the tube.
NOTE: Tighten the Torctite Coupling screws alternately whilst continually checking for slackness of the joint.
6.4.5
Place the second Torctite Coupling over the open end of the LH Radiant Tube, ensuring that it engages fully, up
to the stop. Assemble the Fan Assembly to the LH Radiant Tube ensuring that it engages fully into the Torctite
Coupling (up to the stop) and is positioned with the fan outlet horizontal for flueless applications and either
horizontal or vertical (facing upwards) for flued applications. Tighten the nuts of the Torctite Coupling to secure
the Fan Assembly to the Radiant Tube, taking care to support the Fan Assembly in line with the axis of the tube.
NOTE: Tighten the Torctite Coupling screws alternately whilst continually checking for slackness of the joint.
