Greetings,

I have a 20 year old Burnham steel boiler (model RS110). I recently found
that the inspection port/hole has a gret deal of soot around it. Mostly on
the top. Upon futher inspection, it appears that the firebox material inside
the combustion chamber has "slid" downward, partially obsscuring the port.

I am relatively familiar with the burner aspect of the furnace, the primary
and secondary controls, cleaning & maintaining them as well as cleaning the
boiler flue tubes annually. I have not ever been into or done anything with
the combustion chamber or boiler itself other than take the sides off for
access to clean it or take the bruner assembly out for cleaning, replacing
the nozzl;e and adjusting the electrodes.

I checked the Burnham web site, and they do have a replacement combustion
chamber available. I don't even know if I need one, but I suspect I do. Is
it worth (with the boiler at this ripe age of 20 years) to replace the
chamber, or would I be better off investing in a new boiler? Is this
something that I can do my self or are special tools/procedures necessary?
I have installed a new boilers before (2 times) so I am familiar with the
units in general.

What is entailed in replacing the chamber? Big job? little job? Time?
Should I save myself the time and aggravation and just have someone else
replace the chamber?

Any help or advice is much appreciated. Thanks.
