My sister and brother in law just purchased a Regency 2400 insert just like mine and it is scheduled to be installed the week after Christmas. Mine was installed during warm weather so it wasn't a big deal to open doors and windows to ventilate the house from the odors of the break in fires. Any thoughts on having a couple small fires in the stove while it's outside prior to installation. If not, I suggested that they isolate the great room from the rest of the house with a barrier(plastic drop cloth) and open the windows until the odors are gone. They asked me how I like my insert, my reply is "It's the best purchase I ever made" . We love it.
