Converting B-vent to Vent Free?

[Chuck]

I have had a Regency, B-vent, freestanding fireplace with gas logs running on city propane for 12 years and now want to convert it to a ventless/vent free log set. The problem with ordering new vent-free gas logs is that my existing firebox is so darn small, in size like 21"W x 10"D x 9"H. Other than the obvious difference in venting, and the inclusion of an oxygen depletion sensor (ODS), what else is different about the log sets? burners? I guess my question is this, can I just add an ODS type pilot system to my current gas logs or do I need to buy a different set of logs that will fit?

No ideas???????

Nobody knows what the hell you are talking about.

Oh. I didn't think it was that confusing. I have a functional, but non-efficient "B-Vent" (requires its own flue or chimney) style flue gas stove that I want to somehow try to convert to an energy-efficient (almost

99%) "vent-less/vent-free" heater/stove. What I am trying to determine is how to do this safely. I want to totally close off my existing flue and capture 100% of the heat just as if it were a vent-less model. The only difference I can see between the two models is that the ventless models are required to come with a special oxygen depletion sensor (ODS) as part of the pilot flame apparatus. I was going to replace my gas logs but instead I have cleaned my stove, blocked the flue, removed the glass front door, have run the stove, smell no gas fumes, and constantly monitor the CO with a detector which reads zero. Anything wrong with this setup?

I want to totally close off my existing flue and

te combustion. Where there *is* enough air for complete combustion (which = seems to be the case with your gas stove), CO2 (carbon dioxide) is produced= instead, which your CO monitor might not be sensing.

that you just might not wake up some morning. Your house might be drafty = enough that in the *short term* you might never get a dangerous build-up of= CO2. But really, I would hate to think that someone turned into a vegetab= le when I could have warned him.

eater that would keep one room more comfortable if that's what you want. A= High Efficiency gas furnace (over 90%) that is meant for a whole house sti= ll has a vent, even though its a 2" plastic one. It operates in a fairly a= ir-tight room of its own, with a combustion air inlet and a fan-boosted out= let to get rid of the carbon dioxide and water vapor.

Ok. I found your original question from November 19, 2008. I do not believe you can convert them. Not only are the sensors different, but I believe the burners are also different.

Vanguard sells 18 inch logs and Peterson sells 16 inch vent free.

Hope this helps.

Thanks for the heads up. I am still monitoring things constantly and dont use it at night. I dont see any difference in the gas burners themselves. Nice blue flames with nice orange tips. No smell, plenty of heat.
