    • The Master-Fit® BTR series provides outstanding performance and maximum installation flexibility for both new construction and replacement applications. Multiple options for placement of water connections and low installation clearances are additional installer-friendly features. Master-Fit® water heaters include – The Eliminator™ – that delivers automatic self-cleaning protection against buildup of lime and other sediments. As deposits of lime, and and other sediments accumulate, inside the tank, they form a barrier between the burner and the water, and concentrate excessive heat around the critical weld areas. The result is reduced energy efficiency, higher operating costs and a greater risk of premature tank leaks. Master-Fit® takes a bite out of sediment with the ultimate lime tamer... the Eliminator™ A.
