David, Yes, unless you have working knowledge of pool heaters, we recommend that you have a heater professional install and adjust this heat exchanger assembly. Gas heater can explode if installed incorrectly.

Unscrew top of heater. Keep screws together because there are a lot of them. Pretty easy except two screws were hidden underneath. Took old exchanger out and dropped new one in. Put all screws back. Time consuming but not too difficult but time consuming.
