Commercial Gas Water Heaters

BTR-120

FEATURES

The Master-Fit® BTR series provides outstanding performance and maximum installation ﬂ exibility 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 signiﬁ cantly reduce or eliminate sediment build-up inside the tank

■

Reduced sediment build-up maintains rated thermal efﬁ ciency and reduces water

heating costs

■

Self-cleaning system maximizes tank life

FACTORY-INSTALLED DRAFT DIVERTER AND AUTOMATIC FLUE DAMPER (BTR-120-400 Models)

■

Low-proﬁ le draft diverter helps for installation in tight spaces

■

Automatic motorized ﬂ ue 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

through

SUGGESTED SPECIFICATION

(Natural or Propane) gas water heater(s) shall be A. O. Smith Master-Fit® model # _____________ or equal, with a

storage capacity of __________ gallons, an input rating of ___________________ BTUs per hour, a recovery rating

of_________ gallons per hour (gph) at 100ºF rise and a maximum hydrostatic working pressure of 160 psi. Water

heater(s) shall be protected against 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 to keep precipitated solids

in suspension so that they are removed from the water heater on that or successive draws. Glasslined water heater(s)

shall also be protected against electrolytic corrosion by multiple factory-installed anode rods. In addition, water

heater(s) shall: 1) Be equipped with an integrated control system consisting of a 180ºF adjustable thermostat with

upper and lower sensing bulbs. 2) Be equipped with intermittent electronic ignition, a manual reset gas shutoff

device, a gas pressure regulator, factory-installed, CSA Certified and ASME Rated T&P relief valve and

2-3/4˝ x 3-3/4˝ tank inspection port. 3) Be design-certified by UL (Underwriters Laboratories) to current

edition of ANSI Z.21.10.3 - CSA 4.3 standards governing storage-type water heaters. 4) Meets the thermal

efficiency and standby loss requirements of the U. S. Department of Energy and Current Edition of

ASHRAE/IESNA 90.1. 5) Have a 3-year limited warranty against corrosion as outlined in the written warranty.

For Technical Information and Automated Fax Service, call 800-527-1953. A. O. Smith Corporation reserves the right to make product changes or improvements without prior notice.
