How do I remove the Hayward Gas manifold to get to the orifices?

[Juggernaut]

Hi,

I have a hayward H400FD. Once again spiders have clogged the orifices. I do not want to spent another $150 just to have someone clean them out, but I cannot figure out how to get to the orifices.
See attached picture.

I removed the 4 screws directly on the horizontal bar of the gas manifold, but it does not swing out as I expected it would.

The vertical connection is threaded, but I don't want to pull too hard because I am afraid I might break it.

How do I remove the gas manifold?

Thanks!

Yup

You are going to need to disconnect the gas supply line coming into the gas valve. So shut off the gas coming into the heater, then disconnect the feed line coming in and that should allow you to remove the manifold to get at the orifices.

Any luck with this? I'm having the same issue (and did not fully understand the last reply).
