1. Tube
2 Tube Coupler
3 Swaged section of tube
4 Point at which the Swaged tube
slides into other section of tube
5 Once the two tubes are joined
together , place the centre of
the Coupling over the line of
the joint and torque to 40 ft/lbs.
FIGURE 11 COUPLER KIT
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 FIG-
URE 5 (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) provided torqued to 40 ft/lbs: SEE FIG: 11
(BELOW).
Models 200 & 175 have alumatherm as the first
section with welded flange, all other tubes are aluminized. 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 clamp should then be centred across
the joint before tightening up. If a turbulator is
necessary it will be factory pre-installed. 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.
IMPORTANT:
Turbulators are ALWAYS installed at the
vent end of the heater.
