Q: Please give me the pros & cons for
logs. What is the BTU output and is a heat deflector needed to protect the mantel?
A: AGA Vented gas logs give you the look of a vented gas log
set. The output of this log set (and vented
sets) is determined by the fireplace it is installed in. A heat
deflector is not needed on AGA Vented Gas Logs.
Q: Do you suggest having a
carbon monoxide (CO) detector installed when using gas logs?
A: Yes, I believe that you should have a
carbon monoxide detector installed in every building that has a combustion
appliance. A combustion appliance is any appliance with a flame.
These include: gas furnace, gas hot water heater, wood fireplace, gas fireplace,
vented and vent free gas logs, gas stove, gas range, gas dryer, and most
importantly, if there is an adjoining garage with an automobile. Follow
the manufacturers instructions for mounting. I personally prefer the
digital readout CO detector by Nighthawk.
Q: I got my logs put
in. My question is how can I repaint the inside of the fireplace
to a desirable color? Do I have to use a special paint or will
the gas logs not make it hot enough to matter?
A: Please be
aware that with vent free gas logs (if you choose that route)
cannot have the firebox painted. The vent free logs heat the
paint higher than the 1200 degree F. limit. This will make the
paint carry through the house with the air currents and deposit
the paint residue on everything. Vented gas logs do not have this
problem due to the lower temperatures and the exhaust gases going
to the atmosphere.
Q: I would like to be
able to use gas logs for decoration as well as a source for heat,
and it seems that the unvented type would work the best although
I am concerned about the claim that the fire isn't as
realistic.... if I opened the damper slightly would the fire
become more realistic dependent upon how far I opened the vent or
is it a design difference between the vented and un vented logs
A: The fire on the Peterson pages are accurate as to what to
expect from both vented and vent free. Damper position would
not help flame pattern, that is the limitations on burner and
cleanliness required by the product safety listing. Opening the damper will lower the
heat output for those days when full heat is not wanted.
Q: I have a center
chimney with three working fireplaces....could I still burn wood
in the kitchen fireplace either while the gas logs were burning
A: Gas and
wood cannot be mixed in the same flue. But can be in the same
chimney. Unless chimney is over 75 years old or not built to
code, you will not have a problem. If you have one hole coming
out the top of your chimney for all three fireplaces, then you
have a problem, if you have three (which I suspect), then you
have no problem, if unsure, call a certified chimney sweep to do
you please tell me the best place to put my CO detector? I have a
two-story house, bedrooms on the second floor, gas furnace, water
heater and dryer in the basement, gas range on the first floor,
and will soon have gas logs on the first floor as well. Right now
the CO detector is next to my bed, sort of by default.
A: In my
opinion, it should be a digital readout Nighthawk placed at eye
level. CO has a .97 specific gravity so it mixes floor to ceiling
well with air currents, but I feel you will look at it more at
eye level. As far as placement in the house. I recommend one on
each level. Read owners manual as far as what not to place it
close to, like the furnace.
Q: Can someone tell
me what types of heat gives off carbon monoxide? Gas &- oil. - yes, electric no, wood??? Thanks
monoxide is given off when incomplete combustion takes place.
Combustion appliances (or vehicles) can be fueled by: gasoline,
diesel fuel, kerosene, LP gas also known as propane, natural gas,
oil, wood, alcohol, and the like. If there is a flame present,
carbon monoxide is possible if combustion is not complete.
recently moved into a house that appears to have vented gas logs.
The fireplace has a chimney so I assume the gas logs are vented.
1. Is there a way to be sure of what I have? 2. If my current gas
log set is vented could I replace the vented gas logs with vent
free gas logs? If so, do I need to do anything special?
A: Vent free
gas logs will have tags or metal plates attached to them for
identification. If your gas log set does not have tags, it is
probably a vented set. If you wanted to swap to vent free, you
would remove your old vented set and replace it with a vent free
burner and logs for that burner. There are no parts that would
swap from the vented to the vent free set.
Q: What sized gas
line should I run for gas logs?
size of the gas line varies by the BTUs needed for the gas log
set and the distance of the gas line run. It also varies by fuel,
propane verses natural. Follow this link for a chart of gas ling
Q: What are the
specific functional differences between vented and non-vented
Vented have a better looking flame and
consumes more gas (90,000+- BTUH) vent-free heats approximately 800
square feet and consume up to 40,000 BTUH. But the flame does not look
as good. Great looks and low heat or good looks and great heat,
that is the question!
Q: I have a wood
fireplace and want to buy gas logs, I was told that the gas line
has to down the chimney through the damper to the logs. I was
wondering if is this a proper way to do it?
is not right. Never run the gas line into a high heat area. Go
find another installer that can run the gas line out at the floor
of the fireplace where is should be. Be sure to get a building
permit if required and have it inspected. Follow all
Q: Can we run the gas
line to our fireplace and install gas logs ourselves, or do we
need a professional to do that?
though detailed instructions come with the log set, it is our policy to only
recommend professional installation.
Q: I have gas logs and was told to keep the
glass doors open while the thing was on.....is that right?
A: Yes, your glass doors must stay open while the gas
logs are burning. You can close them immediately after turning
Q: I have a Peterson gas log set. There are
small hairline cracks in a log. I was wondering if this is a
problem? Do we need to watch it for the cracks getting bigger.
The man that installed the logs told us how to temper the set on
a low heat.
A: The cracks do not pose a problem. However, your logs
are warranted for life. Peterson is a great company, they don't
want you to have broken logs in your fireplace.
Q: Should I open the damper when the gas logs
are used ?
A: If vented, the fireplace damper must stay fully open
when in use. This is the same position used with a wood fire.
Vent free gas logs on the other hand are different. The damper
can be fully closed letting all the heat into the room. The
damper can also be used to regulate the amount of heat produced
into the room. In other words you can open the damper to let some
or most of the heat go up the chimney when you want to use it as
a decorative log set.
Q: I have a wood stove. Can I install gas logs
in this unit if the firebox of the stove meet the minimum
requirements of the gas log installation requirements.
No. Gas logs can only be used in open
front fireplaces. To put one in a closed combustion wood stove
would be an explosion hazard. The flames could go out due to lack
of air. When door is opened to see what is wrong - air goes in to
ignite the raw gas. There goes the house and maybe the neighbors.
Serious matter. Do not do it.
Q: I have a gas log set in a fireplace
originally built for wood. The fire goes out. It burns fine for
less than one hour. Why does the fire go out? The pilot light
also goes out. Should I use a grate to hold the logs? Should I
use lava rock (the product sold for grills)?
A: If the fire goes out within 10 minutes, then the
thermocouple is cooling off too much when the logs are started.
The solution is to increase the pilot flame adjustment. If it
will not adjust higher, replace the thermocouple. If too small a
gas line is installed, it will also cause this and would have to
be increased to solve your problem. If the log set burns more
then 20 minutes and then goes out, it is from overheating. Is
there 3" between the valve and the side of the firebox? Is
the shield on the gas valve? The thermocouple could be placed
wrong thereby heating the cold junction on the thermocouple. You
should use the grate that came with the log set. You should use
only accessories for the log set, nothing for a grill.
Q: Is it possible to burn BOTH wood and gas in
a "standard" fireplace insert or is that a No, No ?
A: It is a No, No!!! Let me explain. A wood stove is a
controlled combustion product. This means air is restricted to
increase burn time. This cannot be done on a gas appliance, a air
starved gas appliance does not burn properly. It is possible to
starve the appliance of air to the point combustion that the fire
goes out. Then when the door is opened to check it, air rushes
in, kaboom. It is an explosion hazard and should not be
We don't have natural
gas out where I live, so everything's electric. Everything stays
warm, though, and I only use the fireplace for ambience and maybe
some light-duty toe warming. Firewood is a mess, though. It soots
up everything (the fireplace hearth and surround are snow white
imitation marble), and is a pain to clean up. Since the fireplace
backs up to the garage, I'm wondering if I could switch to
artificial gas logs and run a line through the wall to a BBQ-type
propane tank in the garage. Just a standard 20 pound tank. Would
this work, or is it a stupid idea?
A: First, a smoking fireplace with wood is still a
smoking fireplace with gas logs, it will not cure your problem.
Second, Propane cylinders are not allowed indoors, even a garage. Third, is set
of gas logs consuming 90,000 BTU per hour of gas would burn on
the gas grill cylinder for only 4.8 hours. See this FAQ on
smoking fireplaces. Let's get your fireplace to stop smoking,
then choose which fuel you want to burn in your fireplace.
