Radiant Tube Sub-Assembly:
CAUTION
!
CUT HAZARD - SHARP EDGES.
Wear protective gloves when installing and handling
and cutting radiant tubes.
instructions will result in personal injury.
If is recommend that a maximum of twenty-foot lengths of
radiant tube and possibly an elbow be assembled on the
floor before raising into position.
Experience has shown that it is best to start laying out the
system from the exhauster end, although this is not a
requirement. Avoid small segments that cannot be
supported properly according to the instructions in this
manual.
1. Apply sealer sparingly from the tube furnished to the
outside of the heat tube coupler, elbows, and other
fittings.
NOTE: Failure to use sealer can result in loss of vacuum.

Placement of screws @
approximately 120°
2. Secure joint with sheet metal screws to provide a
mechanical joint rather than rely on friction. Use damp
cloth to remove excess sealer. Heat tube and fitting
assembly ends are designed for minimum clearance and
tight fitting to minimize air in filtration.

3. Insert coupler inside tube section. Be sure the radiant
tube is butted up tightly against the stop rim in the middle
of the coupler. Note: Tolerances are closely controlled at
this point to insure as tight a joint as possible. At this
point make sure that radiant tube sections to be joined
are straight and in line.
4. Attach combination hanger (0464.00) to the radiant tube
at dimensional support locations as outlined in this
manual. Combination hangers should be positioned so
that the locking loop (45° suspension point) faces the
same direction. Combination hanger's (0464.00) shall
be positioned at all elbows and tee's so as to provide
support for the adjoining reflector.
5. Position the intermediate reflector supports (0465 .00)
between the combination hangers illustrated below.
6. Using two or more men, raise the length of pre
assembled tube sections up to suspension height, and
using "S" hooks or turnbuckles attach tube hangers to
suspension hardware.
7. Check to be sure all suspension hardware, chain, wire
rope, etc., is hanging straight. Reposition hangers where
necessary until suspension is straight.
8. Adjust suspension length until heat tube is straight and in
line. If possible, heat tube should be parallel with floor.
9. Proceed in manner described above to complete
hanging the remainder of the radiant tubes as described
and detailed in this owner's manual and the layout
drawing.
NOTE: Review system layout carefully before any cutting
radiant tube. If cuts are not made where shown, radiant
tube lengths may be short and require additional tube
couplers to complete the project.
When cutting radiant tubes, deburr with a file to remove
sharp edges and facilitate easier assembly with the
couplers.
10. Make final check to be sure heat tube is straight and in
line before installing reflectors as illustrated on page 12
and 13.
