Went to the identical burner on a 2yr old 70/90 WB std eff oil boiler in an out house in the country. Boiler shell was completely blocked with soot, despite the boiler being serviced fully & combustion set early in year. All that caused all this was the remains of a mouse, most of it blocking the air partially where it goes to the nose cone.
Was more shredded mouse than mouse jam!
Dont know how to prevent the mice getting into the burner & this is the second time on this boiler!

Get a cat?

Joking aside, a metal mesh screen over the air intake would work.

Didnt see any cat about, lol! :smile: but there are a few dogs there, kept in other out houses. No sign of any food near oil boiler to attract mice, but guess they go to the heat.
Whpes, - a fine wire mesh might work but it is hard to cover that burners air opening properly & to add to the risk, mice seem to always pull the fibreglass out of the boiler wrap which will block that Inter burners air opening as it points backwards close to the wrap. I am wary of the people using too solid a grill to block the air opening & thus reduce the air to burner, putting the setting all out!

I've seen somewhere, and for the life of me I cant remember where, a wire metal mesh with 3/8" or 1/2" squares. if and when I remember where I saw it I'll post it up.

I assumed wire mesh with 3/8" or 1/2" squares is too big & would allow mice through it, so I checked the Internet. Apparently mice have soft skulls & flexible bodies so can get through a hole any wider than 6mm (1/4") & they can jump 18" high! So wire mesh would need very fine or folded a few times to make smaller holes.
