I just moved into a house with hot water baseboard heat. The first thing I did was replace the 30 year old boiler with a Lennox GWB8. The installer insists that the main fill valve be left open. From what I think I interpret here is that the fill valve should be closed after filling. Which is it?
I never owned a hot water heat before. Can somebody tell me the procedure for filling, purging and and pressurizing in simple steps? Does the system have to be flushed periodically?
This is a great forum with lots of usefull information. Thanks for hosting it.
