Actual Port Opening
• Fast Venting
Full open or 7 ⁄ 8 port for the radiation farthest from the boiler or
hard to heat radiation (coldest rooms).
• Medium Venting1 ⁄ 2 or 3 ⁄ 4 port for radiation located between middle and end of
main (warm rooms).
• Slow Venting1 ⁄ 8 or 1 ⁄ 4 port for radiation located closest to boiler (hot rooms).
