Main Vent Question

Bob_43

Could someone with the venting charts please tell me my venting needs. 1 Pipe Steam. Mains spilt in 2 directions 15 feet in one direction, 39 in the other. The mains are 2 1/2 inchs and the returns are 1 1/4. The Main vents are located at the end of the return(1/2 inch pipe) before it drops back to the boiler.

Also, how much will I save if I have my pro drill and tap the end of the mains instead of at the boiler.
Thanks,
Bob

Use

a Gorton #2 on the long main and a Gorton #1 on the short one. If you relocate the vents, the steam will reach them more quickly so they will close sooner, and you won't waste steam filling up the dry returns.

Thank you.
