through
BOOSTER MODELS
The Master-Fit® BTR-151 and BTR-201 are designed for installation in “booster”
applications, to supply commercial dishwashers with very high temperature water…
usually 180ºF. A booster water heater is normally 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,
and hot and cold water connections can be made in the top, front or rear,
for installation versatility.
™
THE ELIMINATOR
• 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
THREE WATER CONNECTION OPTIONS
• Hot and cold water connections can be made through top, front or rear of water heater
• 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

SUGGESTED SPECIFICATION
Gas booster water heater(s) shall be A.O. Smith Master-Fit, Model Number ___________________ , with a 32-gallon storage
capacity, an input rate of __________________ BTU/HR, _________________ gas, and a recovery rate of ________ gallons
per hour at a ________ degree Fahrenheit temperature rise, and a maximum hydrostatic working pressure of 160 psi.
Unit(s) shall have a fan-assisted combustion system, providing a power-induced draft of makeup air prior to burner ignition.
Unit(s) shall be equipped with intermittent electronic ignition with power on/off switch, which shall provide flame failure
response in less than one second. The burner for the unit(s) shall be easily removable. Unit(s) shall be equipped with a
factory-installed temperature and pressure relief valve, and a 2-3/4'' x 3-3/4'' tank inspection port.
The water heater tank shall be glasslined and protected against premature failure in the following ways:
1. Against electrolytic corrosion by multiple, factory-installed anode rods
2. Against failure due to overheating caused by the buildup of scale, film and other sediment by a self-cleaning device,
positioned inside the tank so that it directs the flow of inlet water in such a way that microscopic particles of precipitated
solids shall be kept in suspension and exhausted from the water heater on that or successive hot water draws.
Unit(s) shall meet or exceed ASHRAE/IESNA 90.1-1999, and be design certified by UL (Underwriters Laboratories), according
to ANSZ21.10.3-CSA4.3 standards governing storage-type water heaters.
