Just wanted to follow-up with the Napoleon EPI 1402P fireplace insert I purchased and installed earlier this year. The chimney liner was the most difficult part of the installation, getting the end from oval to round to fit the adapter, but I finally got it. Now that we're in our winter months, where before I would burn a wheelbarrow full of wood each evening, would smoke up the house, and wouldn't really put out much heat. With the new insert, I actually turned off the gas furnace. Using the air control, we open it while getting a fire going, but cut it down to a minimum to slow down the burn. We only burn a small bundle of wood each evening, it doesn't smoke up the house at all, and it keeps our 2200 sq ft home a warm toasty 75 - 82 degrees all night. Also, this unit with the gold doors really made for a beautiful addition to our home. Thanks again for all your help with the selection of such a nice unit. Our whole family really loves it.
