Burner And Tube Installation - Schwank STV-JZ Owner's Manual

9. BURNER AND TUBE INSTALLATION

PRIOR TO PROCEEDING with the tube installation:
Refer to section "8. System Suspension"
IF a 90° or 180° elbow is to be installed in the system, refer NOW to the Elbow Kit in-
stallation instructions supplied with the elbow kit
NOTE: If a turbulator is required in the system, it is factory installed inside clearly labelled
tube(s) with instruction as to where the tube(s) must be installed at the vent end of the
system
1) All hangers must be:
a) Suspended at the same height = horizontal alignment of tubes
b) In a straight line = vertical alignment of tubes
c) Spaced 116" apart = correct spacing for reflector attachment
d) Oriented with the "cavity side" facing the burner end of the system (except the last plate
hanger at the vent end = the cavity side faces the vent)
2) Insert the swaged end of the first tube (tube with flange) through the 4" hole in the first
plate hanger – FIGURE 3
a) Ensure the 'cavity' side of the hanger faces the burner end of the system
b) Slide a Torctite tube coupler past the swage onto the tube
i) The final position of the coupler will be on the 'burner-end' side of the hanger
c) Guide the tube into the second hanger (webbed) – ensure the cavity side of the hanger
faces the burner end of the system
d) Position the first plate hanger 2 inches from the tube flange – this will ensure access to
bolt the burner to the flange
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 the re-
flector
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 tubeb)
b) Adjust the hanger so that it is located on the second tube, approximately 2" 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
