In my house - which I've owned for about 18 months now, there's a
fireplace with a natural gas burning log set... wifey and I were
looking at it last night, trying to figure out if it actually threw
any heat - or was it purely for the nice-fire-burning-atmosphere...
anyways, I turned the gas off months ago when we bombed the house for
bugs. And I couldn't get it lit and didn't want to spend all night on
it. That's not my question.
In the course of looking at the fireplace, I noticed that something
was placed in the damper to keep it from closing fully. But oddly
enough no cold air was blowing down the chimney...
The question - since the damper is open, I am now questioning whether
or not the log set is vented or vent free. Is there a way to tell?

I can't speak to your damper or chimney, but I know of no open fired log
set that does not need venting. There are plenty of sealed log
fireplaces/inserts that do not require chiney vented They are usually
vented through the rear wall, but that doesn't sound like what you have.
Make sure you have a working vent to avoid cabon monoxide buildup. It culd
????? Huh ???? I've been using an unvented gas log set for almost
10 years in my basement/family room. It was purchased from a gas log
fireplace store and they sell LOTS of different unvented units. My
flue is closed and virtually all of the heat comes into the room
rather than up the chimney. I have a CO detector in the nearby
hallway and have NEVER had a problem with CO buildup, moisture, etc
etc etc. My family and pets are all still alive and kicking.

Obviously there are different designs and requirements for different log
sets. The logs we had in our home in Ohio definitely required venting. It
was indicated in the owner's manual and stated clearly by the isntaller.

buffalo ny: when an unvented natural gas burner is installed in my
office, part of the instructions for its use include to open a window

a decorative logset. if there is a gas controlling device related to
the logs, check the labels for more clues. open fires in fireplaces
whether gas or wood require venting. a direct vented gas heater is
enclosed and has a two-way horizontal flue outdoors thru which it
receives its own fresh air and gives exhaust. in the absence of a
manual or model number, the best guess would be you need to replace it
with a modern safer labeled device. since the condition of the
chimney flue regarding cracks or leaks into the house is presumably
unknown as well, let's start by installing a CO detector in the
sleeping rooms, have the chimney relined, install new enclosed heat
rated gas log fireplace vented up the newly lined chimney with a btu
rating to warm the house all the way to its newly insulated walls.
but first have your brother-in-law as santa come down the chimney
with his brand new hd recorder camera and visually check it for
also, next time you're hanging a picture or working on an electrical
outlet, check for actual insulation in the walls. it will be related
to the heat calculations for the btu ratings your new fireplace
if you still have kids, never mind. remove the gas logs, close the
climney with its damper lever and put in a decorative lighted fake
until they are 12.
