Boulevard Direct-Vent Linear Traditional Fireplace features a large ceramic glass window that provides excellent heat transfer and contributes to its exceptional efficiency. The Boulevard's Green Earth Preferred Intermittent Pilot system eliminates the standing pilot - saving energy and your money. When you want to fire, press the button - or just let the programmable thermostat maintain your desired room temperature. Thanks to its advanced logic, the thermostat remote control anticipates heat demand to minimize temperature fluctuations in the room. In the event of a power outage, your Boulevard fireplace can operate with a standing pilot and switch - to provide life-saving warmth for your home until power is restored.
