e) Check that the first tube is level
3) Install a focus shield reflector over the first tube - secure with sheet metal screws to the
hanger at each end
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) NOTE: 100,000 x 20 ft and 175,000 & 200,000 Btuh Systems:
 Refer to Section 9.1, Fig 15
The second tube is unpainted aluminized steel for the 175,000 & 200,000
FOR ALL OTHER INPUT RATES: See FIG 13 below
8) 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
9) CHECK THAT THE SECOND TUBE IS LEVEL, ALIGNED HORIZONTALLY AND VERTI-
CALLY WITH THE FIRST TUBE – MAKE ADJUSTMENT AT SUSPENSION POINTS
AS REQUIRED—THE WELDED SEAM ALONG TUBE LENGTH MUST FACE DOWN
10) Install the reflector over the second tube and fasten to hanger at each end (See Section 10)
11) 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
12) 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
13) Mount the Burner to the first tube flange using the four nuts and bolts provided (FIG 12)
a) Insert two bolts through top holes in burner flange
b) Install gasket onto the two bolts to position it between the burner and tube flanges
