Manufacturers of Water Heaters.  'Heat Trap Flue'

The patented 'Heat Trap' flue, an exclusive Day & Night feature, is the main reason why 'America's Finest' water heaters give more hot water at lower cost. A series of indents in the flue, staggered and baffled, retard rising hot gases and deflect them from side to side, transferring more heat into the surrounding water. This maximum utilization of heat assures speedier hot water service, faster recovery and minimum expense.

Has product images, illustration, description, applications and specifications charts to provide product details.

Unbound from a large rare 1949 Architectural Catalog for Builders, this unique old four-page technical brochure would display beautifully matted and framed. Awesome cover graphics. A fabulous addition to your retro water heating equipment library.
