Recovery capacities are based on 95% thermal efficiency.
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.
