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.
The heater is designed to operate on natural or propane gases.
HOWEVER, 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.
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 latest editions of the
National Fuel Gas Code, ANSI Z223.1/NFPA 54 and the National
