Glenlivet wrote:Finally put in a vent I've been thinking about for some time now. This one is a bivalve 4" and mounted in an un-trafficed but fairly central part of the floor. The idea is to provide a low entry point for incoming air to work with the ceiling vent and allow convection to establish an efficient path for venting of C01 and water vapour from the catalytic heater. The side window was working alright as an air inlet but this should be better.
The other use is a lowest point vent to permit any leaked heavier than air gases to spill out instead of accumulating on the floor.
This cap was riveted on after the pic. The end looks white but it's all galvanized with a bug screen on the inside. Keep the crawlers and rodents from getting ideas.
