Thatch Posted December 22, 2020 Share Posted December 22, 2020 Just got this from our insurance company. Is anyone else be asked for venting to outdoors? We are in a new building the has proper air exchange and is C1D2 compliant. We have a vapor detector and a powered floor vent as well. Each still should be protected for excess pressure and vacuum. Stills should be equipped with vacuum and pressure relief devices that are piped to outdoors. Any condenser vents should also be piped to outdoors. Vents should be sized to discharge the maximum vapor generation possible at zero feed and maximum heating within the pressure limitations of the protected equipment. Vents should terminate at least 20 ft (6.1 m) above the ground and preferably at least 6 ft (1.8 m) above roof level and be so located that vapor will not re-enter the building. Vent terminals should be equipped with flame arresters. Link to comment Share on other sites More sharing options...
