7. BURNER AND TUBE INSTALLATION
With all hangers suspended at the same height, insert first aluminized tube section through 4"
hole into first two wire hangers. Bolt burner to flange on first tube section. SEE FIGURE 5
(page 7). Subsequent lengths of tube can then be installed, joining them together one inside the
other and locking the joints using the aluminized steel coupler. SEE FIG:6 (page 7). 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 clamp. The
couplers should be positioned across the pipe joint center and tightened. If a turbulator is neces-
sary 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 (below) for the models which do require turbu-
lators.
Turbulators are ALWAYS installed at the vent end of the heater.
ELBOW INSTALLATION: When installing a 90° pr 180° elbow in the system, refer to sec-
tion 5 (page 4) and figure 8 (page 8)
