If a steel hydropneumatic tank is in place, replace it with a properly sized diaphragm expansion tank. Otherwise, significant heat transfer problems can occur by causing air to be trapped in the heat exchanger. If the boiler system has an existing expansion tank and the boiler temperatures are being changed, resize the existing diaphragm expansion tank.

Use care when using a torch near the top cover and heat exchanger plate. It is recommended that the front half be removed prior to soldering to avoid potential damage.
