I know this is a little off the tool subject. However, this is the place for the best info. I have found. Looking to install the thing in the basement family room that is 30X18. Do these put out any warm air or are they just for looks? And how about the safety issue as they are not vented where does the gas go? I'm wanting to hear form people who have one and how they like it or dislike a brand or model. We are on LP. Thank you for your input.

Installed propane gas log in a Heatilator zero clearance wood burning fireplace last year in newer, fairly air-tight, home. Unit has oxygen depletion sensor built in, which shuts off gas when O2 is low. Carbon Monoxide (CO) alarm is a must have item, too.

Unit has fans and will produce enough heat to warm the entire 2200 sq ft two story house if needed during rare power outages... (fans are on generator circuit).

I have not seen any instructions regarding an open window requirement. As a long time volunteer firefighter I am very cautious in this regard and have no reservations in using this unit. Enjoy!

I really like my ventless fireplace. I don't know the brand name but recommend that you get one made in the States that is a established brand name. It heats our 1600 sq. ft. house even on the coldest nights here in W. Tn.(Usually no colder than 10 F. It is economical. There have been no deaths in the U.S. with one of these units since they began to make them with oxygen sensors. They shut themselves off if the Oxygen gets too low.(Mine has never shut itself off.) I live in a fairly tight house. I don't leave any windows cracked. One of my windows has a bullet hole through it. I guess that's enough vent.

The only brand name in my opinion to purchase is Vanguard which is produced by Desa International, Bowling Green, Ky. We used to sell and install these units and when properly done will supply 99.99% efficent on LP gas or Natural gas. You will have to purchase the the proper unit for the proper gas type. Units are Not field convertible !!!!! !!!

Just got done installing one in my new place. It is in the library. I have O2 depletion sensor, CO2 sensor and LP gas detector installed per FL code. Unit runs on LP with fake logs. Wife wanted it for astechtics (sp?). I had it equipped with a blower. I can provide model # and other info when I get home.

Vent looking item in the pic is IMPORTANT PAPER!!

She also had an LP fireplace installed in Master BD but it is vented outside. You know, for those cold FL winter nights. hee-hee.

Willie -
Here is what I have installed in the library. It is an unvented (vent-free) universal firebox. Unit is made by DESA International. It is the 42" model with blower. It is a Vanguard Model VFB42C. DESA claims 99% fuel efficiency. It is ZERO clearance and rough out framing size was 48&5/8" W x 44.5" H x 22&5/8 D. I think unit is rated at 33000 Btu.

Here is their Phone Support # 1-866-672-6040 This unit may also be installed in an aftermarket permanently located mobile home where not prohibited by local code. My new home is classified as "Unusaully Tight Construction" so we had to remove a door to another room to air for proper combustion and ventilation.

For more info go to link below or WWW.GOOGLE.COM and query for "Vent Free" or "vent-free".

As for those long winter FL nites, FL code requires direct-vented fireplaces in bedrooms. Direct-vent products feature a sealed combustion firebox, so room air doesn’t come into contact with the flames. The direct-vent design draw outside air to the burners through an outer pipe, while exhaust gases are expelled through a smaller inner pipe. Room air gets heated as it circulates through the passageways around the burner system. Direct-vent products provide about 75% to 80% heating efficiency as compared to the 99% efficiency of the vent-free models.

HTH,
Let us know what you do.

I do not recommend the use of a ventless unit, but if you go ahead and use one make sure it is one equipped with an oxygen deletion device that will shut it off because of the lack of oxygen below a preset level. Most of them also require as a part of the listing/labeling/instructions that a window to the outside be opened 2 inches or more while in operation.

Better do not use them. Once experienced a family almost died. Survived thanks to a neighbour visiting and opened a door. If not in a very drafty room you will at least get a headache either from shortage of oxygen or the built up of cabonmonoxide.

I looked into these a couple of years ago. There are some basic facts about them that may help your decision. One is there needs to be some air turnover in the heated area. This is to keep oxygen level up and to vent the exhaust. These things can burn and cause problems not so much from the exhaust as from depleting the oxygen. Another big consideration is the water that is produced as a combustion product. It can cause moisture problems, wants to condense on the inside of windows. When I was small, we lived in a big old house with freestanding gas heaters in every room. The house was so drafty ventilation was not a problem, but on cold mornings there was ice on the inside of the windows, on cool mornings just a lot of water. I decided not to get one of these heaters because of these problems. My solution was electric baseboard heaters. Not the most efficient thing in the world, but cheap, quiet, easy to control and install.
