1) Install Hangers using chain or other suitable suspension hardware at each side of the
hanger: See Figure 11 next page
i: Two hangers for first section (from burner), and one hanger for each additional section
ii: No closer than 12" (30 cm) and no further than 14" (35 cm) from the burner/tube
flange
iii: No closer than 6" (15 cm) from a tube connection in the system
iv: No further than 18" (61 cm) from a tube connection in the system
v: If angle mounting a 'U' Tube model, the vent side must be in the upper position
2) With all hangers in alignment and suspended at the same height (and angle), insert first alu-
minized tube section on to the first two hangers: See Figure 12A next page
 Also lay the vent end tube on to the first two hangers - check tubes for turbulator la-
bel to ensure the correct tube is located at the vent end
NOTE: INSTALL THE FIRST AND SECOND TUBES (FROM BURNER) WITH THE WELDED SEAM
ALONG THE TUBE LENGTH FACING DOWNWARD
3) Fasten flanged tube to hangers with 'U' bolts:
 All tubes on the burner-side of the heater are bolted to the hangers with 'U' bolts
 Tubes on vent-side simply rest in the hanger notch and do not fasten to the hanger.
4) Bolt burner to flange on first tube section -
IMPORTANT NOTE: Models with inputs 175,000 & 200,000 refer to section 9.3
5) Slide a Torctite tube coupler over the swaged end of the first tube, then join the second tube
over the swage in the first tube -
6) Slide the Torctite coupler into position across the center of the tube joint -
7) IMPORTANT: TOURQUE THE COUPLER BOLTS TO 40 ft-lbs
8) Subsequent lengths of tube can then be installed on both sides of the hangers by joining
them together swaged portion inside the next tube and locking the joints using the Torctite
coupler.
SEE FIGURE 9.

Note that 155 x 20'U requires field installation of a 2 ft turbulator (packed in Burner Kit carton) in
the swaged end of the third tube in the system (1st tube after turn box on vent run side)
9) Install Turn Box: See Fig 12B
 The Turn Box has "long" and "short" tube legs
 The 'long' leg attaches to the burner-run tubes
 The 'short' leg attaches to the vent-run tube side - tubes end short of burner for con-
nection of vent pipe
