My annual challenge with my pool heater has once again begun early this time. Surprisingly the heater fired up quickly after I opened the pool during a quick test. I had the usual after winter cleanup and finally got to a point where I wanted to start heating the pool. After a maddening couple of hours of cleaning leads, testing continuity, etc. the heater finally fired up. However, I noticed that the first two burners (from left to right) have no flame. I've never done anything with the burners before. My heater is now eight years old. Any suggestions on how I can get those burners fired up? Thanks for any help.

Your burner orifices have spider nests in them. Very common.
You can try to clear them with a piece copper wire bent in a hook about an inch long. Steel wire can scratch the orifice and change gas flow into the burner.
If you can't do it that way, it takes either a 3/8" or 7/16" wrench to remove the orifice. Just blow the debris out and reinstall. Be sure the orifice is threaded back in about the same distance as ones you haven't touched. No sealant is used.
Thanks for the response and great info. I'll give that a try tomorrow. Much appreciated.
I just wanted to report back, that did the trick. 7/16" was the correct size to remove the orifices. I pulled the two, they were clogged, cleared them out and the heater is running great. Even the initial ignition is more consistent. Thanks again for the help!
