FOREWORD
The design of models BTI-80 and 100 comply with the latest version 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.

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:
National Fuel Gas Code, ANSI Z223.1 / NFPA 54 and the National Electric
Code, NFPA 70;
In Canada:
Installation Code CAN/CSA B149.1-00 and the Canadian Electric Code CSA
C22.1.
These are available from Canadian Standards Association, 8501 East
Pleasant Valley Road, Cleveland, OH 44131 or National Fire Protection
Association, 1 Batterymarch Park, Quincy, MA 02269.

Manifold Pressure Electrical Characteristics
MODEL Type of Gas Inches W.C. kPa Volts/Hz Amperes
BTI (80, 100) Natural Gas 3.5 0.87 120/60 <5
All Models:Maximum supply pressure = 14.0 in. W.C. (3.48 kPa)
Minimum supply pressure, Natural gas = 4.5 in. W.C. (1.12 kPa), Propane gas = 11.0 in. W.C. (2.74 kPa).
Minimum pressures must be maintained under both load and no load (static and dynamic) conditions.
