FOREWORD
The design of model BBCN375T754NV complies with the current edition
of ANSI Z21.10.3/CSA 4.3 as automatic storage or automatic circulating
tank type water heaters.
Installation diagrams are found in this manual. These diagrams will serve
to provide the installer with a reference for the materials and method of
piping necessary. It is highly essential that all water and gas piping be
installed as shown on the diagrams.
In addition to these instructions, the equipment shall be installed in
