It is item 11 on the JXi \/ IXI combustion chamber diagram, and Zodiac lists a different assembly for each heater size: R0589402 for the 200 and R0589405 for the 370.\u003c\/p\u003e\n\u003cp\u003eWater balance matters for heat exchanger life. The IXI manual warns that if pH rises above 7.8 without calcium hardness and total alkalinity properly maintained, calcium can coat the copper tubes inside the heat exchanger, restricting flow, reducing efficiency and possibly damaging the heater. If pH drops below 7.2, acidic water can dissolve copper tubing. Damage to the heat exchanger caused by improper water chemistry is not covered by the warranty.\u003c\/p\u003e\n\u003ch3\u003eThe Rating Plate Rule (rev.
