The Kingsman ZCV3622 Direct Vent Gas Fireplace - 36" adds to the tranquility of your entertaining area. The lifelike gas logs create the perfect backdrop for the flames and are sure to attract your guests' attention. Choose from a variety of inside decorative liners, including porcelain reflecting and brick designs, to personalize your Kingsman ZCV3622 Direct Vent Gas Fireplace - 36". The millivolt valve mechanism in this fireplace does not use electricity, but it does have a standing pilot that allows operation with hi-low heat and flame control during a power outage. The electronic intermittent pilot ignition employs an electrode to ignite the pilot. When the appliance is not in use, the IPI system guarantees that the pilot flame extends across the burner for rapid activation, and it saves energy. This fireplace incorporates a flame sensor that continuously monitors the pilot flame and shuts off the gas completely if the pilot is not detected, ensuring safety and reliability throughout your fireplace's operation. This unit's direct vent system is a simple closed flue system that allows air and combustion gas to enter and escape through the same coaxial flue pipe, making it one of the most energy-efficient gas stoves available.
