Warranty

The warranty of the manufacturer extends only to the original retail purchaser and is not transferable. This warranty covers brand-new products only, which have not been altered, modified, or repaired since shipment from the factory. Proof of purchase (dated bill of sale), model name, and serial number must be supplied when making any warranty claim to your OSBURN dealer. This warranty applies to normal residential use only. This warranty is void if the unit is used to burn material other than cordwood (for which the unit is not certified by EPA) and void if not operated according to the owner's manual. Damages caused by misuse, abuse, improper installation, lack of maintenance, over-firing, negligence or accident during transportation, power failures, downdrafts, venting problems, or under-estimated heating areas are not covered by this warranty. The recommended heated area for a given appliance is defined by the manufacturer as its capacity to maintain a minimum acceptable temperature in the designated area in case of a power failure.
This warranty does not cover any scratch, corrosion, distortion, or discoloration. Any defect or damage caused by the use of unauthorized or other than original parts voids this warranty. An authorized qualified technician must perform the installation in accordance with the instructions supplied with this product and all local and national building codes. Any service call related to an improper installation is not covered by this warranty.
