Never !!! Wasnt delivered like said. Charged 129% fr installation & had to purchase new gas line & vent fr delivery man to install .never needed the new Line or vent & lowes would not reimburse us the 129$ .my husband could have hooked up our original gas line & vent but lowes said No! Policy was they had to charge 129 & we buy the parts .which we never needed & got ripped off from lowes fr. Never sent the delivery ticket to the delivery man so was 2 days late & I had to call lowes to find out why it wasn't here the day it said or who knows when it would have been here. Complete ignorance & sales people dont kn how to do their job right !
