The heaters are approved for optional U-Tube 
configurations. This installation requires 1 or 2 U-
Tube packages depending on configuration desired.
Shown below is an example of a typical 80' (24 m) U-
Tube configuration. The U-Tube may be installed in 
either a standard horizontal position or in an opposite 
45° position as shown below. When designing a U-
Tube configuration, the following additional rules 
must be adhered to:

• A minimum of 10' (3 m) on TF-120/160 and a min-

imum of 15' (4.5 m) on TF-200/250/300/ 350/380 
is required between the burner and the U-Tube.

• The correct turbulator (

See Page 24, Step 7.5) 

must be installed in the last standard section of 
tube.

• The burner must never be operated in a tilted 

position.

• When installed in a full 45° position, the burner 

must be installed on the lower side.

• The heater must be properly supported at all loca-

tions.
