We have had an insert made by Regency. It is model number Gi29le. The that installed it has been here with three different crews trying to figure out why the offgassing is so toxic. It is nothing they did or we did, and we followed the advice and have done we the recommended burn off procedures and have operated the insert for almost 20 hours. The offgassing is so toxic that we can’t be in certain parts of our house near the fireplace, even when it is not on. We have to open doors and windows to ventilate the house. We are asking the installersto remove the insert and will likely have to get a disaster cleanup company to come in. It is making our eyes and throat burn, and sometimes we feel sick to our stomach. A friend was here for a couple hours, and left with a severe headache. Our dog even has trouble breathing at times. This company needs to take responsibility for the outcome of their manufacturing process, which results in this horrible offgassing. It was a costly endeavor to have this installed, both in terms of our health and money. We are also thinking we may have to call the local health department.
