water line on steam boiler

@ March 16, 2011 4:43 PM in water line on steam boiler

I am having a problem with the water line on a relatively new steam boiler installation.This problem happens with the vacuum system on or off.When the steam boiler(gas fired) first goes into low fire (until the boiler reaches 140 deg. ) Then goes to high fire,the water line goes from normal to all the way to the top of the sightglass and becomes erratic.When the boiler satisfies in hi fire and shuts down,the water level drops immediately,brings on the condonsate pumps and the boiler goes off on LWCO. WHAT IS GOING ON HERE!
Thanks in advance for any help, SERVICEWIZ

R-410A Oil

@ March 4, 2010 12:50 PM in R-410A Oil

I have been recently told that a vacuum pump will not pull moisture from POE oil,you must use a filter-drier to remove the moisture.If that is the case,what is the procedure for repair on a system which has developed a leak and is found to be down to atmospheric pressure?What is to be done with the moisture in the oil?
