9. BURNER AND TUBE INSTALLATION
With all hangers suspended at the same
height, insert first aluminized tube section,
through 4" hole in first end plate hanger and
onto wire hanger. End plate hanger should
butt against the sight glass on the bottom of
the tube, SEE FIGURE 4 (PAGE 8).
Bolt burner to flange on first tube section,
SEE FIGURE 10 (BELOW). Subsequent
lengths of tube can then be installed, joining
them together one inside the other. The
joints are then secured together using the
aluminized steel coupler (c/w 2 bolts) pro-
vided, torqued to 40ft/lbs: See FIG: 11 below.
Models STS-p 200 & 175 have alumatherm
as the first section with welded flange, the
Second section is aluminized, and the other
Subsequent lengths are steel painted.
Slacken the bolts and slip the clamp over the
end of the tube to be joined, making sure the
swaged end of the tube is fully inserted into
the plain end of the tube before re-positioning
the coupler. The coupler should then be cen-
tred across the joint before tightening up.
If a turbulator is necessary it will be factory
installed into the tube(s). The tube(s) will be
marked stating where it must be installed in
the system, see TABLE 4 (PAGE 11) for
models which require turbulators. Noting:
Turbulators are ALWAYS installed at the
vent end of the heater.
