If you're looking for a balance of efficiency, convenience, and style, then you may want to consider a direct vent stove. Direct vent stoves are a type of gas stove that use a special double-wall pipe instead of a traditional masonry chimney. This allows them to be extremely flexible in terms of placement and very effective secondary heat sources. And, just like all of our other hearth appliances, our direct vent stoves come in a large variety of sizes and styles - you'll have no problem finding one that suits your tastes.
I need to convert two B vent stoves over to direct vent. The problem is currently both stoves vent into a single exhaust tube within my chimney. The chimney was filled with superflu so I cannot install two exhaust lines due to chimney inner width restriction. What is the pipe height required from stove to overhead exhaust outlet, 24 or 56 inches?
The first thing to consider is the feasibility of making a B-Vent to direct vent conversion. If your stoves are listed for such a conversion, then obviously it can be done. Also, chimney/venting requirements for each stove will depend on the manufacturer's stated guidelines in the respective owner's manuals. Please review this information before beginning the project to ensure proper protocol and code can be followed.
