Why The Monessen Solstice VFI33 Millivolt Is Worth The Investment
This isn't just a fireplace insert, it's built with a self-powered millivolt control valve that doesn't require 110V AC to operate, giving homeowners a genuinely power-independent heat source that generates its own electric charge for safe shutdown during a gas interruption or flame-out.

True Power Independence, Built Into The Valve Itself. Unlike ignition systems that rely on 110V AC power, the millivolt control valve is a self-powered combination gas control that generates its own small electric charge, meaning this fireplace remains fully operational for both heat and safe shutdown control even during an extended power outage.
