The FL Series consists of unvented, high-intensity heaters that use modular ceramic burners to maximize fuel efficiency and reduce combustion byproducts, the company says. They are rated from 20,000 to 120,000 Btuh input. Both series operate on either LP or natural gas. Fostoria Industries, Inc., 1200 N.
