Baseboard steam piping.

I am installing baseboard elements on a two pipe steam system for a customer. I have little experience and no one in Alberta that I can find does as well. Do I need grade on my elements and do I need a thermostatic rad valve and steam trap on each run of elements.

    You do need a trap at the outlet, and it will run more quietly with pitch on the element. Limit your element length to no more than the supply pipe is sized to deliver; any more will be filled with condensate and not give the heat you might expect. Remember, the same size pipe has different capacities, whether it is vertical or horizontal.

    Yes -- as @Noel says, you do need grade on the elements -- I would suggest no less than 1 inch in 10 feet. Slope them towards the outlet end. You will need a thermostatic radiator trap at the outlet of each one. You should have an inlet valve for each one as well -- it will make servicing easier -- but it isn't absolutely necessary.

    Also, for the sake of the future, make sure that there is a conveniently accessible union on both the inlet (usually between the valve and the inlet spud -- if it is a true steam valve, the union will be part of -- and matched to -- the spud and the valve) and the outlet (also usually between the outlet spud and the trap).

    Do you have 1 element/enclosure? or are the elements stacked in the enclosure? Might make a difference

    In the Slant/Fin "finned tube catalog" we added a page "Element Application of Steam" several years ago. (it is old information that Slant/Fin published years ago) It is a good reference that lists guidelines to follow. This Finned Tube Catalog is available on the Slant/Fin web site.

    I think it's so cool when manufacturers participate in this forum, I wish more of them did, even though I understand there are sometimes reasons for their reluctance.

    Some of them are "reluctant" because they've made some bonehead moves and we called them out on it. I could tell a few stories about that..... Slant/Fin, however, has done quite well over the years.
