For electronic gas pool heaters , those with a digital display, make sure that your heater is truly powered down by removing the power source. If your replacement gas heater is the same as your old one, take note of how your old one is wired as you are disconnecting the wires. Your new pool heater may be wired differently however. Disconnect the gas plumbing from inside of the heater, with the use of two large channel locks or two pipe wrenches.
Be certain that the gas supply is turned off before this is done. On Natural Gas heaters , look for a union connection inside the heater to disconnect. Propane lines are typically a flexible copper tubing. Be careful not to crimp or bend the tubing during removal. Of course, no smoking or any open flames near the heater at this point.

For steel or copper heat sinks, remove the bolts on the header flanges, to disconnect the water plumbing from the heater.
