Taking the burner back out

Well the burner is back out. Not quite as we had planned but what are you going to do.

To my delight it actually came out a lot easier then I had expected. Everything has seemed to hold up with the exception of the of Stainless liner having starting to warp. I assuming that I had held it in place with two many bolts so I'm going to remove a few to allow for some more room for the material to expand.  

 I've started fitting the 3/4" rope seal and noticed that I will need to remove some of the Ramcote 1200 around the various openings so that everything will fit back together nice and tight. I'll be holding the rope seal in place using small common nails so won't fall into the burner during the re-installation.

A bad seal.

 Sometimes success is bitter sweet. Today we went to start the Stanley from cold for a second time. When cycling the main burner on I noticed a lot of vapor coming out from the base of the boiler. I had noticed the vapor on the initial startup but assumed it was water vapor coming off the insulation in the burner pan. On the second startup I was not quite as convinced.  My suspicions of this being vapor was confirmed when the boiler reached 150 PSI and we got a nice sized tube fire.

 Upon inspection of the burner, looking for leaks, I couldn’t find any sources that would produce the volume of vapor I was getting. I had made a great attempt to seal the burner with fiber frax but it seemed that I must have overlooked something. I decided a call to Pat Farrell was in order to see if he could provide some insight as to what might be happening.

 Pat quickly sorted the issue out to being a lack of a burner rope seal.  Unfortunately I was unaware that there needed to be an actual seal when you were running an outer burner pan that overlaps the outside diameter of the boiler.  The outcome of all this is that the burner needs to come back out so that the seal can be installed.
