AHI in AR Posted November 9, 2013 Report Share Posted November 9, 2013 That's odd. Irregular hole that isn't from factory. Smoke stain above hole and apparently unaffected galvanized liner behind it. Probably won't cause huge problem with gas logs, but weird nonetheless. Quote Link to comment Share on other sites More sharing options...
Marc Posted November 9, 2013 Report Share Posted November 9, 2013 Don't those ventless things come with knock-outs in them? To accommodate gas pipe entry at various points? Marc Quote Link to comment Share on other sites More sharing options...
AHI in AR Posted November 9, 2013 Report Share Posted November 9, 2013 On the sides. Never the back. Don't those ventless things come with knock-outs in them? To accommodate gas pipe entry at various points? Marc Quote Link to comment Share on other sites More sharing options...
hausdok Posted November 9, 2013 Report Share Posted November 9, 2013 That space between the firebox and the back wall - the galvanized metal you see, is supposed to be where air flows around the box. The heat from the flame heats the air in that space and it rises and leaves via the louvers above the firebox. As that air rises it is replaced by colder air entering the heat exchanger at the bottom. He cut a hole in one wall of the heat exchanger. Why? Who the hell knows but if a client were to ask me what I thought about it I'd probably tell him the guy that cut that hole must be a moron. ONE TEAM - ONE FIGHT!!!

AHI in AR Posted November 9, 2013 Report Share Posted November 9, 2013 On every one I've seen there are two galvanized walls. We are seeing the inner one; there's an outer one behind that and the air from the home flows between the two. That forms a sealed area separate from the firebox itself. The firebrick panels aren't airtight around the edges. They're really there more to protect the galvanized panels from excessive heat.
