Customer Question

I have a raypak 2100 gas pool heater. I changed the plastic header. It was leaking..once I fired it up with the new one installed. It makes a banging noise from that area as the heater is working. Loud banging. Any ideas?

How many times does it bang while running and heating?
Customer: replied 2 years ago.
Constant banging as it runs. You can feel it through at the header. Was not doing it with old header

You could have an airflow issue through the manifold. Something could be causing it to expand and contract causing the banging. It would be hard to say exactly without being on site to see it, but it likely has to do with the header you replaced.
