First MegaSteam! (Gordo & Steamhead)

with the MST-396. We dropped into the existing header on this one, as we have done so many times before. Burnham says you can get away with a 2-inch header, but a 2-1/2" on this size boiler dries out the steam even better.

We did order the piping kit from Burnham to see how it went together, and used part of it, including the Y for the Hartford Loop.

The castings on the MegaSteam are genuinely beautiful. The entire unit is very well thought out. It really is a "plug and play" boiler since everything plugs into the electrical enclosure on the right side. And it's quiet- much quieter than the old Utica which also had a Beckett AFG. The combustion test showed 87% combustion efficiency, 351º stack temp, zero smoke, 12% CO2 (I had it up to 12.8% and still had zero smoke) and about 30% excess air. These numbers are far and away the best I've seen on a steamer.

Three things we'd wish for: Include a service switch in the electrical enclosure (there seems to be plenty of room for one), supply a 1/4" brass street ell and ball valve for the sight glass blowoff, and supply a brass pigtail instead of a steel one. We installed a brass pigtail from our stock- steel pigtails just plug up too easily- and added the blowoff upgrade for easier accessibility and so the blown-off water wouldn't dribble onto the cast-iron burner door- makes it look messy. Also, a Vaporstat option would be nice, maybe with a low-pressure gauge in addition to the 0-30 PSI gauge required by Code.

But overall, it's a great boiler. Kudos to everyone at Burnham for bringing it out. And thanks to Glenn Stanton for all you do!
