9.1 TUBE AND BURNER INSTALLATION

Refer to the Single-Stage , Two-Stage Model, or Modulating Supplementary Manual for turbula-

tor locations and tube kit assemblies for the various model input rates.

1) At each hanger use chain, cable, and/or other hardware rated for minimum 100 lb [45.5 kg]

load

i: The first hanger (plate hanger at burner end) is to be located no closer than 3” [75mm]

and no further than 5” [127mm] from the burner/tube connection

ii: Subsequent wire hangers are to be located no closer than 6” (15 cm) either side of a tube

connection in the system, and no further than 24” (61 cm) either side of a tube connection

in the system

2) The first hanger at the burner end is a plate hanger with 3

suspension tabs.

i. Use the center suspension tab for horizontal orientation of

the reflector, or one of the side suspension tabs for angle

mount of the reflector (45°) over the tube

ii. Suspend the plate hanger so that the bottom of the tube-

opening in the hanger is at the desired height for the tube

above the floor (“H”)

iii. The reflector attachment flanges on the plate hanger

face away from the burner

3) Suspend the next hanger (wire hanger) in alignment and at the same tube height as the plate

hanger

i. Distance between first & second hangers is maximum 107” [2718 mm] and minimum

87” [2210 mm] … also see 1) above.

4) Insert the combustion tube section into first two hangers with swaged end of tube toward the

vent. The tube must be level along its length.

NOTE: FROM BURNER END, INSTALL THE FIRST AND SECOND TUBES ONLY WITH

THE WELDED SEAM (ALONG THE TUBE LENGTH) FACING DOWNWARD (in

the bottom hemisphere).

Labels on tubes identify those with turbulators and indicate their location in the system.

5) Install burner to combustion tube: SEE DETAILS - FIGURE 8 NEXT PAGE

IMPORTANT NOTE: Models with inputs 180,000 to 250,000 refer to section 9.2

6) 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

7) Slide the Torctite coupler into position across the center of the joint - SEE FIGURE 9

8) IMPORTANT: TOURQUE THE COUPLER BOLTS TO 40 lb-ft.

TORCTITE COUPLER CAN ONLY BE USED ONCE. IF COUPLER IS LOOSENED OR RE-

MOVED FOR ANY REASON, REPLACE COUPLER WITH NEW ONE. TORCTITE COUPLER
