For the Kingsman ZCV39 Decorative Zero Clearance Direct Vent Gas Fireplace - 39", choose between a millivolt or intermittent pilot ignition system. The millivolt valve system 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. Please note that the optional Kingsman remote attachment shown below is not approved on Decorative Appliances in the United States. The Kingsman Flex Kit (4" and 7" dia.) - 5' is required for this item. Please select one of the choices below if you haven't already done so.
