Steam Boiler-How Not to Do It...
Saw this steam boiler yesterday in a Ballard commercial business (1 pipe steam). No header, No Hartford Loop, No skim tappings, No combustion fresh air, melted neoprene insulation, vent damper disconnected, No chimney liner, No redundant LW cutoff. Of course, no boiler permit was ever pulled. Someone apparently never installed one or bothered to read the instructions.
