Figure 3. INSTALLATION The depressed corner box shown is not supplied by Fives. This box is recommended to shield the burner while assur- ing that the hot end of the tube is completely immersed to prevent overheating. The immersion tube should be made of schedule 40 pipe or steel tubing with all welds tested for water leakage. A 3/4" plugged drain should be provided at each return bend to remove condensed water from the tube. If possible, locate drains so they are easily accessible and can be opened without draining the entire tank.
