New Boiler Skimming
Installed a a single pipe Peerless 63-03 last week and the installer doesn't know how to skim it, and won't follow the installation manual. He had brought some unknown boiler treatment liquid but I opted out of it and arranged for a credit and chose to skim myself.
As per Peerless, using washing soda I skimmed from the 1 1/4" port for 3 hrs in two sessions until the water was relatively clear and while doing so I kept smelling burning oil. This smell persists while the boiler is steaming with the soda in it. The previous boiler was also gas. I get quite a bit of rust as well as metal flakes when I drain it. I also see grey flakes floating on the surface. Is it dope? Could the rust and the metal flakes be coming from the pipes and not the boiler? When I drain the return, a cupful comes out rusty but then it runs clear. I also see no metal flakes. I have however, checked this only once.
After 3 rounds of boiling and draining, the water line bounces approx half an inch, a
significant improvement over the 3-3.5" when I first started. The water is still not clear, but I was wondering if I should continue to skim now or resume after using the boiler for 4-5 weeks?
My EDR load is 295 sq ft. This boiler is rated at 309 sq ft and my previous boiler which cycled excessively was rated at 357 sq ft, but would reach 1 PSI in 25 mins. This boiler takes much longer to generate steam and the pressure from a cold start reads 0 for the first 30 mins. Steam reaches the main vents in approx 18 mins including the Cyclegard interruption. The pressure stays at 0.5PSI for another 20 mins before going up. It eventually cuts out at 1.5PSI. The stat is set to 75 and ambient temp is 73. The radiators take longer to get hot but the vents have stopped gurgling and hissing; actually they have never been quieter. My pipes have 1" insulation. Is the pressure situation normal? I am concerned that when it gets really cold in NYC the boiler might not be able to keep up.
Thanks for your feedback.
