Your installer tech, Christian, deserves recognition.  He was polite, industrious, and totally knowledgeable of his job and product.  He proceeded rapidly to remove  the existing unit, clean out the area, then install the new unit. After cleaning again, removing all leftovers and tools, he patiently  showed us the the process of usage and insured that we were pleased with the new fireplace – and we were and are!!!
Thanks for the fine service & product
