I had an electric outlet installed in my former wood burning fireplace just for this insert. This was fairly easy to assemble.  The embers are very lifelike.  The heater is an added plus. The flames are very dim so I will be contacting manufacturer for assistance. If the flames were working properly I would have given 5 stars.  Wayfair had the lowest price with  fast free shipping.This is the popular model DLG 1058.  I include this because it is hard to tell on Wayfair website.
