4) Install three reflector stabilizers on the bottom of the reflector
a) Equally space stabilizers with one at the reflector center point
b) Firmly bend the end tabs on each stabilizer up over the ‘trough’ at each side of reflector
5) Slide a Torctite tube coupler past the swage onto the next tube to be installed
6) Insert the swaged end of the tube into the next hanger to support its weight.
7) Slide the female end of the second tube over the swage of the first tube
a) Ensure that the swage on the first tube is fully inserted into the second tube
b) Adjust the hanger so that it is located on the second tube, approximately 2" (5 cm) from
the end of the tube – in this location the hanger supports both tubes.
c) Slide the Torctite coupler into position across the center of the joint
d) IMPORTANT: TOURQUE THE COUPLER BOLTS TO 40 ft-lbs
e) The coupler is now in place on the ‘burner-end’ side of the hanger
8) CHECK THAT THE SECOND TUBE IS LEVEL, ALIGNED HORIZONTALLY AND VERTI-
CALLY WITH THE FIRST TUBE – MAKE ADJUSTMENT AT SUSPENSION POINTS AS RE-
QUIRED—THE WELDED SEAM ALONG TUBE LENGTH MUST FACE DOWN
9) Install the reflector over the second tube and fasten to hanger at each end (See Section 10)
10) Repeat these steps assembling one section of tube and reflector at a time until the system
is complete
IMPORTANT: TURBULATOR LOCATION IN SYSTEM - REFER TO TABLE page 24
11) ENSURE THAT THE SYSTEM IS LEVEL AND THAT ALL TUBES ARE ALIGNED HORI-
ZONTALLY AND VERTICALLY – MAKE ADJUSTMENT AT SUSPENSION POINTS AS
REQUIRED—WELDED SEAM OF 1st & 2nd TUBES MUST FACE DOWN
