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 

accordance with those installation regulations in force in the local area 

where the installation is to be made.  These shall be carefully followed 

in all cases.  Authorities having jurisdiction should be consulted before 

installations are made.

ROUGH-IN DIMENSIONS

FIGURE 1.

The installation must conform to these instructions and the local code 

authority having jurisdiction.  

In the absence of local codes, the installation must comply with the following:

In the United States:

Current edition of the National Fuel Gas Code, ANSI Z223.1 / NFPA 54 

and the National Electrical Code, NFPA 70;

In Canada:

Current edition of the Installation Code CAN/CSA-B149.1 and the 

Canadian Electrical Code CSA C22.1.

These are available from Canadian Standards Association, 8501 East

TABLE 3, GAS AND ELECTRICAL CHARACTERISTICS

All Models:  Maximum supply pressure = 14.0 in. W.C. (3.48 kPa)

 

Minimum supply pressure, Natural gas = 6 in. W.C. (1.49 kPa). 

 

Minimum pressures must be maintained under both load and no load (static and dynamic) conditions.

Recovery ratings are based on 80% thermal efficiency.
