6.7.1
Remove the packaging/protection from the Radiant Tubes and ensure that they are clear internally. It is
recommended that the appliance is suspended in sections which are joined by the use of a Torctite Coupling
once in position. Appliances may however, at the discretion of the installation engineer be assembled (less
reflector panels) prior to being suspended, in which case due consideration must be given to the means by
which the appliance is to be safely raised into position.
6.7.2
Place the Radiant Tube and Radiant Tube Assembly (containing turbulator) on trestles, providing 150mm
minimum clearance above the floor and assemble the four Hanger Brackets to the Radiant Tube and Radiant
Tube Assembly, using one 'U' bolt per bracket (from fastenings pack). Position the Hanger Brackets along the
Radiant Tube and Radiant Tube Assembly as shown in Fig. 25. Ensure that the welded seam of the tubes is in
contract with the hanger brackets i.e. facing away from the reflector. Tighten the 'U' bolt nuts sufficiently to
retain the Hanger Brackets. Do not overtighten.
IMPORTANT: ensure that the turbulator is positioned adjacent to the Fan Assembly and orientated as shown
in Fig. 26. Failure to assemble the Radiant Tubes with their welded seams facing away from the reflector will
void the manufacturers warranty.
Fig 26
6.7.3
Place one Torctite Coupling over the end of the Radiant Tube (see Fig. 25) ensuring that it engages fully, up to
the stop. Assemble the Control Box to the 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. 10). 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.
6.7.4
Place a second Torctite Coupling over the end of the Radiant Tube Assembly at the end where the turbulator is
secured to the tube, (see Fig. 25 and Fig. 26) ensuring that it engages fully up to the stop. Assemble the Fan
Assembly to the 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 or either horizontal or vertical (facing upwards)
for flues 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.
6.7.5
The two sections of the appliance should now be raised and suspended from previously fixed chains or drop
rods as detailed in Section 5.1, at suspension points indicated in Fig. 25. Rope or webbing slings should be
used when lifting from above. If using a forklift to position the appliance sections, ensure that they are balanced
on the forks prior to lifting.
6.7.6
Place the third Torctite Coupling over the open end of one Radiant Tube ensuring that it engages fully, up to the
stop. Assemble the second Radiant Tube into the Torctite Coupling ensuring that it engages fully, up to the
stop with the Hanger Brackets aligned with those of the first Radiant Tube section (see Fig. 26). Tighten the
nuts of the Torctite Coupling to secure the two sections of Radiant Tube to one another, taking care to maintain
the tubes in a straight line.
NOTE: Tighten the Torctite Coupling screws alternately whilst continually checking for slackness of the joint.
