Husband is building us a 24 x 24 den addition. We want a wood burning fireplace insert that is SUITABLE for new construction. Also insurance is saying the UL certification. It seems like everything we see is for NOT new construction. and it seems like when you look at the prices, it is for just the stove and then you need to make sure you get the doors, the frame the blower whatever. We just want all that we need and to know what triple insulated pipe to use with it so we can frame out the hearth/fireplace area. Any ideas????
