TABLE 3, GAS AND ELECTRICAL CHARACTERISTICS

MODEL		Manifold Pressure			Electrical Characteristics
	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.

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.

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, NFPA70;

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.
