We are able to provide you with the replacement parts required for your fireplace for a minimum of 25 years following its purchase. Few manufacturers offer such a long service guarantee. We know from experience that our fireplaces require very little maintenance and since we manufacture most of the parts that go into making them ourselves, we know that we will have no difficulty to honor this commitment. The proof: we have already offered this service guarantee for 25 years. To find out the terms of our 25-year Limited Guarantee, consult the fireplace Owner's Manual.
