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.

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.
