ASME & Non-ASME models with Millivolt Technology. Using self-generated power from the pilot and thermopile assembly to operate the flue damper, there's no need for electricity with these models. The continuous pilot ignition system eliminates lockout situations and utilizes a simplified control system for easier operation.
