Moline vapor vacuum system
I have a house where there is a Moline system with a condensinmg loop in the basement. The original vacuum main vents are missing and were replaced with standard main vents. Does anyone know where to get vacuum main vents?0 -
except
you may not need a vacuum vent -- they were really needed for old coal-fired units, and aren't so necessary (if at all!) on oil/gas. You do have Dan's book, don't you?Br. Jamie, osb

Vacum Vents
Hoffman does not recommend use of the #76 vent with newer furnaces. If you're using coal it's OK. Contact Hoffman for more information.0
