need a steam pressure cycle switch

@ February 27, 2010 5:02 PM in need a steam pressure cycle switch

I need to replace my steam boiler pressure switch.  I have read on this board from a few different threads for a two floor home I should set the switch to .5 psi and the differential to 1 psi.  The problem is my boiler keeps going up past those settings to 4 psig and then shuts down.  I have changed the gauge with a brand new one to make sure it was not a faulty reading but the gauges are correct.  The current pressure switch is a Honeywell but I would like to know if there is something better on the market.  A friend of mine bought a brand new Honeywell switch and it was not operating at the correct pressures he set it to. Is there anything better out there?

correct level

@ January 30, 2010 11:59 PM in correct level

Hello, this is my first post here.  I need some help with an old Weil-McLain model H5.  For many years I have been manually filling it to halfway on the glass.  I want to buy the 101A-24V feed valve which is the correct one for the boiler.  I noticed a strange thing when I was looking at the boiler.  I was looking at the low water cut off Mcdonnell-miller 67 which has the feed contact.  The float switch is very low compared to the sight glass. The float would only let me have about one inch of water showing in the sight glass.  The sight glass is 6 inches long?  Is this correct?  What is the proper level to keep the water?  I also noticed the fill contact and the low water contact are very close to each other in regards to the water level?  When my boiler makes steam the water level bounces up and down many inches.  Wouldn't this trigger the low level and shut down the boiler. One more thing I should mention is this boiler also make domestic hot water.  Thank you for your help. Joe
