WARNINGS AND STATEMENTS
INSTALLATION INSTRUCTIONS
The installation must conform to the requirements of the authority
having jurisdiction or, in the absence of such requirements, to the
National Fuel Gas Code, ANSI Z223.1-latest edition or CSA
B149.1 latest edition for natural gas and propane. The installation
must also conform to the additional requirements in this Slant/Fin
Instruction Book.
In addition, where required by the authority having juris dic tion,
the installation must conform to American Society of Mechanical
Engineers Safety Code for Controls and Safety Devices for
Automatically Fired Boilers, No. CSD-1 or CSA B149.1 latest
for natural gas and propane
edition
in the above requirements, then the more stringent requirement
will apply.
This boiler, gas piping and accessories must be installed,
connected, serviced and repaired by a trained, experienced
service technician, familiar with all precautions required for gas-
fired equipment and licensed or otherwise qualified, in
compliance with the authority having jurisdiction.
This manual must be left with owner and should be hung
on or adjacent to the boiler for reference.
