9.1. SEMU / ITU ’U’ TUBE SYSTEM ~ BURNER AND TUBE INSTALLATION
SEMU / ITU: With all hangers aligned and suspended at the same height, install first alumin-
ized tube section, onto the first two hangers. Fasten tube to hangers with ‘U’ bolts. All tubes on
the burner-side of the heater are bolted to the hangers - Tubes on vent-side rest in the hanger
notch and do not fasten. SEE FIGURES 4B & 5
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 alu-
minized steel coupler. SEE FIGURE 7.
Note: If angle mounting a ‘U’ Tube model, the vent side must always be in the upper location.
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 .
