FOREWORD
These designs comply with ANSI Z21.10.3/CSA 4.3 as an automatic
circulating or automatic storage tank type water heater.
Heaters having an input of 305,000 (89 Kwh), 365,000 (107 Kwh)
and 390,000 (117 Kwh) Btuh with a recovery rating of 277.3
gph (1049 Lph) or more also comply with ANSI Z21.10.3 as an
automatic instantaneous type heater.
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.
This model water heater is designed and manufactured in both
natural gas and propane versions. MAKE SURE the gas on which
the heater will operate is the same as that specified on the heater
model and rating plate.
These heaters may be installed on combustible floors.
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 Road, Cleveland, OH 44131. NFPA documents
are also available from the National Fire Protection Association,
1 Batterymarch Park, Quincy, MA 02269.
