FOREWORD
The design of the BTP 540A through 740A models complies
with ANSI Z21.10.3/CSA 4.3 as an automatic circulating tank
and an automatic instantaneous type heater. The BTPV 540A
through 740A models are designed for sidewall venting and
direct venting applications and are certified under UL 795.
Detailed installation diagrams are found in this manual. These
diagrams will serve to provide the installer with a reference for
the materials and methods of piping necessary. It is highly
essential that all water, gas piping and wiring be installed as
shown on the diagrams.
Particular attention should be given to the installation of
thermometers at the locations indicated on the diagrams, as
these are necessary for checking the proper functioning of the
heater.
THE HEATER IS DESIGNED TO OPERATE ONLY ON NATURAL
GAS.
THESE HEATERS MUST NOT BE INSTALLED ON
COMBUSTIBLE FLOORS.

Based on 80% thermal efficiency obtained in A. O. Smith engineering laboratories.
NOTE:
To compensate for the effects of high altitude areas above 2000 feet, recovery ratings should be reduced approximately
4% for every 1000 feet above sea level.
