A vent-free Millivolt Loft Burner may also be installed as a decorative appliance in a vented fireplace to provide ambiance and light – but without the heat. In a vented installation, the burner cannot be operated by thermostat, and the flue damper must be blocked open.  A damper clamp is included with all Loft burners.  Because IP Loft Burners include a thermostat remote and may not be installed as decorative appliances, a non-thermostat remote is available.
