INSTALLATION

•
Place the first (flanged, aluminized) tube in the first two hangers (Figure 9). Be sure the flange is toward
the intended burner location. The other end of the tube should have the first coupling already loosely
fitted.
•
Always use all the hangers supplied. As a rule the combustion tube (first tube) utilizes 2 hangers and
thereafter 1 hanger per 10’ section. It is required that the first hanging point be 2” to 8” from the burner
mounting flange, and tube weld seam must face down, refer to Figure 9 for more details.
