These designs comply with the current version of the American National
Standard for Gas Water Heaters, Volume III, ANSI Z21.10.3 / CSA 4.3 as
an automatic circulating tank water heater, and automatic storage water
heaters.
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.
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.
In the absence of local codes, the installation must comply with the
current editions of the National Fuel Gas Code, ANSI Z223.1/NFPA 54
and the National Electrical Code, NFPA 70. All documents are available
from the Canadian Standards Association, 8501 East Pleasant Valley
