Warren Technology Warranties
Warren Technology guarantees the heater section consisting of the resisting coils and supporting racks (except fusible links and overcurrent fuses) for a period of (10) ten years from the date of installation or ten years and six months from the date of manufacture, whichever occurs first, when in the opinion of Warren, the heater has been properly installed and is energized under normal operation.

Normal operation means that the airflow must not be interrupted or stopped when the heater is energized. Dirty filters must not decrease airflow and/or other causes and should not be operated on other than rated voltage.

Warren Technology guarantees the controls, consisting of contactors, thermal hi-limit, terminal, and fuse blocks, etc., for a period of ten years in normal operation, and at rated voltage. Click on the link below for the complete warranty policy for Warren Unitary Heaters.
