The Eastman 0.75 V Brass Millivolt Thermopile Generator is a purpose-built replacement for legacy millivolt systems, delivering a precise 0.75-volt signal to energize gas valves in standing-pilot appliances. Built with durable brass and engineered for reliability, this generator is designed to perform where millivolt power is still king—such as in traditional fireplaces, gas logs, and other valve-controlled setups.
Why this matters
In many older gas appliances, the thermopile is the heartbeat of the safety and control circuit. When it weakens, pilots drift, valves chatter, and the flame becomes unreliable. The Eastman 0.75 V Brass Millivolt Thermopile Generator steps in as a targeted, high-quality replacement that restores consistent operation, minimizes nuisance outages, and preserves the authentic performance of your millivolt system.
