Steam boiler plumbing.

Its time to install the steam boiler plumbing connections. The Isomac steam boiler has four 1/4″  holes along its top. We actually need to make six connections so I had to add a couple of  Tee connectors and mount the  Vacuum breaker, Safety Valve and Steam Pressure Gauge off the one point. The Water level Probe, Pressure-stat and Steam Valve Outlet fill up the remaining three positions.  The other items are the water filling and the hot water outlet tubes which are both on the left side of the boiler, below the waterline.  The lack of space above the boiler means that I had to make extension tubes to offset and lower level of the valves and pressure-stat before they would fit under the top cover of the machine.  I just need to add some electrics now and will will have some steam. ~richard
