The IntelliFire Touch® auxiliary module is required if adding a fan, lights or power vent and using the IntelliFire® Wi-Fi module. Remotes, controls and lighting parts operate the fireplace and its accessories. Compatibility depends on your fireplace control system, so confirm your model number and control type before ordering.
