Question regarding; Vent Free Logs: smells, heat & respiratory and concerns,
Q. My husband just had Open Heart Surgery, We had a Fireplace Build 30/years ago and have been using a large buck stove. Because of his health conditions, we decided to go to Vent Free Natural Gas Logs. We have had a gas smell since we have had them installed.
The installer of our Vent free gas logs has been back and everything is correct. Today I called the Gas Company, no gas showed up on their monitor, but they could also smell the gas, “just a small odor”.I do not burn these thru the night, only from around 11: am to 8 or 9: pm and sometimes not that long, the biggest problem the gas order is smelling stronger in two bedrooms 20 ft away. Nothing would show up on the gas company’s monitors, but they to could smell the odor.
First, they claimed it was our cold air return, but we do not use our furnace/heat and cut the logs off at night. Then they came up with when we took the buck stove out, there is a lot of creosote back in where the stove was which is now open and the logs are setting in. He is claiming the creosote is melting and causing the smell Is this correct. Is there any product that I can get to clean this since it is baked on?
Answer— Creosote is a fuel and “could possibly ignite into a fire, and it does stink! Odors move as air moves in many homes. It is my experience that some air is “still moving”, even if the furnace is not running, or pushing or blowing the hot air out of the vents
If any creosote is visible at the start of one of our repair or installation projects, we would have included a price to remove all of this creosote from the firebox, smoke chamber and chimney flue with a product called Heat Shield PCR (Poultice Creosote Remover) manufactured by CeCure LLC; c/o Saver Systems www.ChimneySavers.com/pcr
In most cases, this is not cheap to repair, but it does work and it will remove the creosote problem.
$1,200 to $1,900 dollars and possible higher are not uncommon. Once again PCR has resolved stinking flammable creosote problems for us.
We would have also included what is called a level 2 chimney cleaning inspection with our chimney scanning equipment, as it is viewed as a “change of use” of fuel source according to the NFPA 2:11 or National Fire Protection Association, the standard for Chimney, Fireplaces, Vents and Solid fuel Burning Appliances.
. . . . WITH ALL OF THAT BEING SAID, LET’S TALK ABOUT
VENT-FREE GAS LOGS
With that being said I’m personally not a fan of vent-free logs at all. My customer’s odor problems alone and this is just one reason that I stopped selling Vent Free Gas units altogether.
Take some time to read your manufacturer’s installation instructions, as well as their printed CAUTIONS section.
To the best of my knowledge, most manufacturers will state something about opening a window while the vent-free products are in use, which seems somewhat defeating when you think of it.
How long of a period of time they can be burned is also referenced.
I also feel you may be using these logs way too long of a period of time but again follow your Mfg. instruction or call their help or customer support line.
I have often read heath cautions on the use of vent-free gas around seniors, small children as well as family members with respiratory problem warnings; to seniors, small children along with individuals with breathing problem would knock out about 85 % of families that I know of, from installing these log sets, including myself with my own bouts with asthma.
It has been stated that burning 100,000 BTU of natural gas in any form, generates about 1 gallon of water. So my question is, so where does that water go, especially since the chimney flue is now closed up tight. Another possible issue is the dramatic rise in temperature of surrounding masonry, wood mantel and any possible hidden. construction framing on the sides or the fireplace or under the hearth.
I know well that many fireplace shops and chimney contractors sell lots of these vent free units to a homeowner on the warmth benefit, and many of their customers really love them. For me personally, I know well that vent free appliances’ actually do produce a huge amount of heat, but for me, it comes with a high cost, as well as potentially to many health and safety concerns to my customers, as well as my own family.
I hope that I have shed some additional insights, on possible solving your issue.
