I can't get at four wire loops securing the cast iron ribbons to the chassis.

The first figure is a zoom-in of what I'm dealing with. I've removed the manifold in the front, but I can see four wire loops in the back (drawn in magenta), and there's no way i can reach in there.

The second figure I've circled the "coffin chamber" where the suckers are located.

I've done the obvious and removed the back panel (item #20) but the coffin chamber remains closed off to my hands.

Any ideas? It's a Bryant BW1 early 90s water boiler, and a very serious delayed ignition issue. I want to clean those burners but I can't get them out. Thanks.

I don't know have not seen one BUT if you can brush the tops of the burners with a wire brush and blow a lot of compressed air thru them you may get it done. Ideally you want to remove them and poke thru the slots. Maybe someone here knows how to remove them but it could take 8 or more hours to find someone or no one knows and replies.

Take s shop vac and suck out as much as you can and them put the hose on discharge and let er rip. Or blow it out with a leaf blower. Necessity is the mother of invention.:wink2::vs_karate:

can you get a small wire brush in to brush the tops and take any loose stuff off then vacuum or blow with air?

Yuri, WhatsRns,

Your quick replies and desire to help are much appreciated.

I did take a toilet brush and suds to the tops of the burners, and leaf blowered a couple times but the scary BOOMs continue to shake the house. I wouldn't be surprised if they've already done permanent damage to the furnace.

I've only seen compressed air used to clean laptops and it's not clear to me there's enough pressure to dislodge oxidation from the pinholes. I'll give that a try and also try to find a test tube brush to possibly ramrod into the burners.

Go to HDepot or a hardware store and see if they have wire brushes. Wire brush you scrape BBQ grills may work but a longer one is better. The boiler is probably quite sturdy and not likely to be damaged but you should get a Pro to check it. Mainly for safety to see if it is producing or leaking CO carbon monoxide.

The delayed ignition is usually caused by an entire burner not igniting quickly enough. This is caused by the top burner holes nearest to the front, being partially restricted enough, so that the gas doesn't flow out to reach the pilot or the adjoining flames quickly enough.
I would use stiff wire directly down into those top front holes to clear any possible obstructions as well as put a flexible brush into those venturi openings to clean them out from the inside.
