My standard aluminum Vans valve came with circa 2009 RV3 kit. When the valve is open to admit hot air from the heat muffler, it also opens to the FWF air under the cowl. The intake to the heat muff on the baffle intake ramp is also generously vented to the underside of the baffling.
1-Why is the hot air pressure relieved so much by venting at both ends of the heated air source ?
2-What keeps CO and fumes out of the cockpit ?
3- Are the new stainless units referenced in the stainless valve post any different regarding contaminated air ?
