The beast is in the basement
. A friend and myself rigged the boiler in the basement. I built a ramp, used some rigging chain, safety rope, rigging straps, a come along and an engine hoist. It went relatively easy. Once the boiler was at the bottom of the ramp, we moved the engine hoist to the basement, my friend held the tag line (wrapped twice around a pole) and slowly let slack out, I picked the boiler with the hoist.
As for the gas boiler and the steam piping, the piping is all 2". There are two tees on the header for the distribution piping for the house. There are wet returns, one under the floor, and one that runs along the wall. The final size is 1" 1/4 pipe for the returns.
The gas boiler has a drop header installed. There are four two inch valves, two for the gas boiler, and two ready to receive the piping from the aa260 boiler. Be back later
