FOREWORD
Detailed installation diagrams are in this manual. These diagrams
will provide the installer with a reference of materials needed and a
suggested method of piping. IT IS NECESSARY THAT ALL WATER
AND GAS PIPING, AND THE ELECTRICAL WIRING BE INSTALLED
AND CONNECTED AS SHOWN IN THE DIAGRAMS.
CHECK DIAGRAMS THOROUGHLY BEFORE STARTING
INSTALLATION TO AVOID POSSIBLE ERRORS AND MINIMIZE
TIME AND MATERIALS COST. SEE FIGURES 1 THROUGH 5 AND
TABLES 1, 2, AND 3.
This design complies with the current edition of ANSI Z21.13-CSA
4.9 for Gas-Fired Low-Pressure Steam and Hot Water Boilers.
MAKE SURE THE GAS ON WHICH THE BOILER WILL OPERATE
IS THE SAME AS THAT SPECIFIED ON THE BOILER RATING
PLATE.
The boiler 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 Electrical Code, NFPA 70 or CAN/CSA B149.1, and CSA
2 C22.1. The former is available from the Canadian Standards
Association, 8501 East Pleasant Valley Road, Cleveland, OH
44131, and both documents are available from the National Fire
Protection Association, 1 Batterymarch Park, Quincy, MA 02269.
