Features

N/A The Master-Fit® BTR-151 is designed for installation in booster applications, to supply commercial dishwashers with very high temperature water, typically 180 ºF. A booster water heater is generally used in conjunction with a standard water heater water delivering hot water at a lower temperature to meet the non-dishwashing needs of a restaurant or other foodservice application.

With a 32-gallon storage tank, these compact units measure only 45" high with a hot water outlet in the top and both top and cold water inlets in the front.

The Eliminator™ Self-Cleaning System
  • Designed to significantly reduce or eliminate buildup of lime, sand and other sediment inside the tank.
  • Reduced sediment buildup helps Master-Fit® water heaters maintain their rated energy efficiency and reduce water heating costs.
  • Self-cleaning system also helps prolong tank life.
Built-In Induced Draft Blower
  • Produces power-induced draft of makeup air prior to burner ignition.
  • Provides more efficient control of heat through the flue collector.
  • No draft hood or barometric damper required.
Rated as Category 1 Appliance
  • Can be commonly vented with other Category 1 appliances, using standard metal type "B" vent.
Permaglas® Ultra Coat Glass Lining
  • Exclusive process provides superior protection against corrosion.
  • CoreGard™ anode rods with stainless steel core provide additional corrosion protection.
  • The Eliminator™ self-cleaning device operates when cold water is connected through front.
Intermittent Electronic Ignition
  • Eliminates standing pilot.
  • Includes power ON/OFF switch.
  • Provides flame failure response in less than one second.
