8. SUSPENSION SYSTEM
The system configuration and available support locations must be considered in order to lo-
cate the radiant tubes correctly. Labour and material can be reduced by locating (system con-
figuration permitting) directly under structural members such as joists, steel or wood beams,
etc.
Chain is recommended for hanging the tube system, connecting the hangers to beam support
as illustrated in FIGURE 3 (below). To support burner and keep it level, a separate suspension
chain must be attached to the eye hook at flange end of burner angled slightly back over
burner, FIGURE 4A & 4B (below). This will permit normal expansion and contraction of the
tube system. (If rigid devices such as rods are used in place of chain, swing joints or other
means of sufficient length must be provided to compensate for expansion.)

9. SEM / IT STRAIGHT TUBE SYSTEM ~ BURNER AND TUBE INSTALLATION
SEM / IT: With all hangers aligned and suspended at the same height, insert first aluminized
tube section, through 4" hole into first two wire hangers. SEE FIGURE 4A.
Bolt burner to flange on first tube section, SEE FIGURE 6. Subsequent lengths of tube can
then be installed, by joining them together one inside the other and locking the joints using
the aluminized steel coupler. SEE FIGURE 7.
IMPORTANT NOTE: Models with inputs 175,000 & 200,000 refer to section 9C.
Note: Turbulators are ALWAYS installed at the vent end of the heater .
