For seasonal shut-downs, always allow water to pass through the heater, even if the heater is not being used. If the heater is isolated with chlorinated water or in its water piping, chlorine gases may corrode the heat exchanger. Rheem Thermal’s warranty will be voided where chemical corrosion is clearly diagnosed as the cause of failure. -
