Old post-- But I'm in a bit of confusion with the venting and clearing of the soffit etc... I've got the Same Mr Heater 45k.. I also ordered the horizontal vent kit.. With reading the instructions, it say's the venting has to be 4' from any soffit and 12" from the wall etc.etc.. I'm basically doing the identical thing as the OP..BUT,, In the pic of the exterior vent being that close to the soffit??.. IS that code????? I wanted to do the same thing, but essentially extend the piping 12" from the edge of soffit... Just want the inspecor to be happy.. any advice before I start cutting through the wall?? Just don't want to get it all done and the Inspector to Red X me... From Olds, Alberta.. TIA
