The patented 'Heat Trap' flue, an exclusive Day & Night feature, is the main reason why Panelray Gas Heaters give more heat at lower cost. A series of indents in the flue, staggered and baffled, retard rising heat gases and deflect them from side to side, transferring more heat into the surrounding room area. This maximum utilization of heat assures maximum comfort and minimum expense.

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