I put a 2" round brush on my cordless drill and clean the tubes from the bottom up spinning slowly. Coal burner, I have a latch on my round door. Looks factory to me. I agree it is not nessesary though.
That will depend on what boiler the unit has on it some tube boilers had 1 3/4" Tubes Others came with 2 1/4" tubes
Let me guess The latch is a flat piece of bar stock with the nut holding it on to the spring Handel bolt .
Most round doors did not have them I guess later they where added like I said seen over one hundred of them only two had a latch on them which where home made . I was told by a guy that was a efm dealer for over 30 years 1953 to 1985 that the early ones never came with a latch only a spring Handel bolt with a nut on the inside like all the ones I see or
seen . Does not real matter does not need one . A gasket is all you need to seal the clean out door remember you want to beable to take it off for yearly cleaning it still help you clean out the fly ash from the smoke self area .
