I have put in cotter pins in the past when I do shear one but I was wondering what the exact size should be.
Further this will be my 3rd full season running. I take summers off. usually run into the end of May and start back in the fall. I clean the tubes and ash out as well as scrape the sides of the firebox. I run a light all summer long inside to reduce any condensation or moisture some.
My question is. Being this is the 3rd year without any major teardown. Is it time that the screws come out and the pot comes out for any maintenance? Grate replacement?
Any recommendations greatly appreciated.
Just call the shop were you bought the boiler the pins will be sent to you . But you do need to find out what is the cause that
is breaking them I been running mine 3 years with the same pin & I use buck never broke one somthing is not right should
not break them like that unless you burning rock in it or a lot of dirt /fines in the coal
