Features

Features

 N/A 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.

The Eliminator™ Self-Cleaning System
  • Designed to significantly reduce or eliminate sediment build-up inside the tank.
  • Reduced sediment build-up maintains rated thermal efficiency and reduces water heating costs.
  • Self-cleaning system maximizes tank life.
Factory-Installed Draft Diverter and Automatic Flue Damper (BTR-120-400 Models)
  • Low-profile draft diverter helps for installation in tight spaces.
  • Automatic motorized flue damper helps minimize standby heat loss.
  • BTR-500 Model features induced draft design and no damper.
Three Water Connection Options for Added Flexibility
  • Hot and cold water connections can be made through front, top or rear of unit.
  • Eliminator™ system operates when cold water is connected through front.
Permaglas® Ultra Coat™ Glass Lining
  • Exclusive process provides superior protection against corrosion.
  • CoreGard™ anode rods with stainless steel core provide additional corrosion protection.
Intermittent Electronic Ignition
  • Eliminates standing pilot, saves energy.
  • Includes power ON/OFF switch.
  • Provides flame failure response in less than one second.
