Note: In January 1996, the circuit boards for Minimax Heaters were changed at the terminals by request of the American National Standard Institute (ANSI) and the American Gas Association (A.G.A.), the two approval agencies for the manufacturing of gas heaters in the United States. If you have a heater manufactured before January 1, 1996 and you receive a newer circuit board with the smaller terminals and the older thermistor has larger connectors, the larger connectors can be crimped so they will fit tight on the newer circuit board terminals, contact a Pool Service Professional for details.
