what do we have here?
original floor in dining room and 1942 newspaper
I had an unexpected surprise when I pulled the floor up, which I'll get into in my next post. But any who, with the floor up and a hearth base built, next was adding reinforcement for the chimney supports. There is a main support that mounts to the wall just above the clean out Tee that support the entire chimney, so this had to be anchored to some substantial wood. Also had to build a support box in the ceiling for the fire block. Each floor has to have a fire block that the chimney run through. I am using Duratech piping system made by Duravent. They have several variations but I'm going with the best line they have. It's double-wall stainless steel, and not cheap - but I'm not going to play around when it comes to fire. It's actually quite easy to install, the 4 foot sections twist and lock together. As far as building a chase, only 2 inches clearance is required.
The design is a cross between the fireplace at the old house, and the fireplace in the Swarthmore house we almost bought. The "fireplace" is just a chase for the stove piping, but will give a more authentic appearance then having exposed piping or a small chase surrounding the pipe, plus allows us to have a mantel. Basically when done will appear to be a real fireplace with a stove inserted in the hearth like our old house was. The walls of the structure will be covered in cement backer board, then covered with a brick veneer, inside and out. This will meet code and give an authentic appearance. The hearth will be either tiled or slate. Would love to match the green arts & crafts tile in the foyer, but way to expensive. I made sure to add a nailer around the mantel level, which will be oak and wrap around the sides and end against the back wall.
Looks good so far
The panels were repainted. The cast iron front door assembly was sandblasted, repainted, the original sight glass repaired, and gaskets added to the doors. Some vent holes from its coal days were sealed to stop any unwanted drafts through the boiler. The cast iron exhaust elbow had a crack repaired and an early unused damper sealed and new plate made for back cover. The expansion tank was flushed and repainted. I repacked the original valves, went over the old gauges and rewired everything. Most important, I added a local emergency disconnect on the side of the boiler and at the top of the basement stairs - both must be in the on position for boiler to operate.
With the main boiler reassembled and thoroughly cleaned inside, next was the oil burner. It's a Beckett burner, the Chevrolet of oil burners. I went through a complete rebuild making it like new condition. The tip was OK which I cleaned and reused - I wish I had noted the size as you'll see later though. With the burner done I needed to come up with a better mounting solution. My dad and I came up with a design and he fabricated it out of stainless steel plating. It's basically a big L, with a base plate with lock downs to hold the burner and a vertical plate that covers the opening of the boiler with a hole to allow the burner to poke through. Everything is sealed with high temp gaskets. An in line filter was then added and the assembly installed.
With everything fitting together as designed, the front disassembled one more time to install a new firebox, which was in desperate shape. I found a universal one on EBAY that worked perfect. I was able to center the new one better inside the boiler with just the tip of the burner entering. You don't want the flame to close to the back wall of the firebox which will disrupt the flame pattern.
Old and new fireboxes
So I'm sure at this point you're saying Hey, great, now it's nice looking ancient oil hungry beast. Well you'd be surprised. The paperwork with the boiler had the burner measured in the mid 80% range. But, then there's the efficiency of generated heat and transfer of that to the system?? Yes, I thought of that too. The biggest problem with these old coal units is you have this huge firebox that you throw heat into, which quickly is drafted into the flue and up your chimney taking probably 50% the heat you just made with it. So the question is, how do modern boilers slow this down and increase the transfer? Well one of the main ways is adding baffles, creating a "torturous path"for the heat and gases. Basically the longer the heat and gases created by the burner stay inside the boiler, the more that will get transferred to your water. Also the sizing of the firebox area is much smaller, concentrating the same heat to the boiler tubes at a much higher level than the early boilers - you don't need all that room for coal anymore. Well what we came up with was a self designed baffling system to obtain the same modern solutions. Firebricks were stacked in the corners supporting 1 inch square stock steel running across the front and back walls. Then two plates were made that sit above the firebox in the middle and lean against the outside "water wall" tubes - the initial and highest point of heat transfer in a boiler - basically creating a V shape. What this now does is re sized the firebox area to about 1/3 the original area, and forces the heat created against the sides of the boiler where the tubes are and then up to the secondary stages of the boiler. Also the small opening left for the heat to escape to the secondary stages slows down the draft. Will it work???? You'll see....

Oh well, thats only 4. Well, I'm supposed to spread the five facts flue to five more victims - but at this point it's an epidemic. If I can track down any who haven't been caught I'll pay it forward.
The NJ radiators - first one ready for it's new home
So how does a 5 foot 6, 150 pound weakling get 4 radiators twice his weight into the house by himself?? Well first he gets a chain fall and rigging so he can lift them off the ground in the garage - oh and don't forget to brace the beam your lifting from that is starting to split in two. Then build a cradle that will sit in a dolly that will support them upright while I wheel them to the back door. Don't forget to make ramps to roll off driveway and across the lawn.
Lifting into the house
Next step took some forethought. When re constructing the walls in the back, I added a reinforced header above the door so that I could rig up the chain fall and hoist up and through the back door. So after taking the chain fall from the garage and setting up again above the back door, you can see the results. Actually worked quite easily.
Setting in place in the Parlor
Once through the door the radiator had to be placed back on the dolly and then rolled through the house. Then I staged it for lifting again where it would be installed. This had to be done before the drywall was up since I had to use the above joist to rig the chain fall again. Next I picked it up off the dolly and set it down where it would be hooked up. I did have to hang the drywall behind the rad now or else would be very difficult later.
... again for the foyer
... and the dining room
The last NJ rad went in the corner of the kitchen next to the stove. Another (the long short thin tube from the parlor) will be installed under the large kitchen window. Finally the mystery radiator that was found never even piped will finally get it's very own piping in the powder room.

Well I cleared the first hurdle unscathed.... but, how do I get two more upstairs... by myself?? After some thought and more busy signals on the phone, I came up with a plan. Out comes the old chain fall again, this time mounted above the butler stairs doorway in the kitchen. Well I am able to hoist on the landing but now the hard part. I turn the corner on the landing and lay scrap plywood on the steps as a ramp. Then I get two 2x6's sistered together and nail across the opening for the stairs on the 2nd floor. Now I use this to rig the chain fall to and slowly ramp the radiator up the incline, then work into the hall. Finally I'm able to slide this one on plywood (to protect the floor) into the kitchen and stage for piping. Then it was repeat for the 2nd that will eventually go in the bathroom.
Piece a cake!
After all that, I then got to spend the next 4 weeks piping all these bad boys into the existing system. I was able to borrow a pipe stand, ratchet threader and pipe cutter, which made work a little easier. I won't bore you with the whole process, but it was just basic measure, cut, thread, dope, and install - aaaand repeat. And sweat like a hog cause it was July and 90's the whole time.
New piping through first floor kitchen to added upstairs radiator.
With the back walls now completed in the kitchen modification, it was now time to focus on the floors in the back addition. There were three issues that needed to be dealt with.
I continued adding support around the perimeter and for the center joists, I sistered them to the others and extended to the south wall. Cross bracing was also added here as to prevent twisting as well as for support where the dividing wall will be located and toilet/tub locations.
I continued with the sub floor installation, but held off on insulation until the plumbing is complete. I added 1/4 inch backer board to the sub flooring in the powder room area for a tile floor and then built a dividing wall to form the powder room. The ceiling framing you see was from the 1971 bathroom, which I demoed only up to this point. It was pretty straight, so this saved me building a flat ceiling in there.
Now I have a new solid floor with a smooth transition to the old kitchen and to our new powder room. This completes the structural changes for our new kitchen/powder room. Whew!
