Induced Draft
BTN Gas Models
80% thermal efficiency—
Low NOx
The Master-Fit
®
Plus BTN series meets Southern California and Texas
low NOx standards and features induced-draft design. This provides
more efficient control of heat through the flue collector. Like all
Master-Fit water heaters, the BTN series provides outstanding
performance and maximum installation flexibility for both new
construction and replacement applications. Each unit is designed to
be as much as a foot shorter than the models they usually replace,
and multiple options for placement of water connections and low
installation clearances are additional installer-friendly features.
The Eliminator
™
Self-Cleaning System
As deposits of lime and other sediments accumulate inside the tank,
they form a barrier between the burner and the water,
concentrating heat around the critical weld areas. The result is
reduced energy efficiency, higher operating costs, and a greater
risk of premature tank leaks.
The Eliminator
™
directs incoming cold water under pressure
to sweep the bottom of the tank to keep sediment
moving so it doesn’t accumulate. Reduced sediment
build-up helps maintain rated thermal efficiency and
reduce water heating costs. The self-cleaning
system also helps prolong tank life to ensure year
after year of reliable service.
