Start with your main vents

measure the length and diameter of each steam main and we can tell you what you need.

venting info

there is an e-book available from the shop here listing the capacities of all the various vents. my view is: you can never be over-vented on the main lines, as long as they are more or less equal [if more than one line].

therefore the gorton #2 is my choice, and if your mains are big, maybe several!

concentrate on improving  the main vents  first, as they do all the work, and get all the abuse. most likely your rad vents are ok. if they are not, then you will see that after your replacement of the mains.--nbc
