WARNING
LIQUEFIED PETROLEUM (L.P.)
PROPANE GAS-FIRED BOILERS
Installation location ONLY as permitted in paragraph entitled
"LIQUEFIED PETROLEUM (L.P.) PROPANE GAS-FIRED
BOILER LOCATION" on page 3 of this instruction book.
The abo
ve warning does not apply to NATURAL gas-fired boilers.
The installation must conform to the requirements of the authori-
ty ha
ving jurisdiction or, in the absence of such requirements, to
the National Fuel Gas Code, ANSI Z223.1-latest edition. The
installation must also conform to the additional requirements in
this Slant/Fin Instruction Book.
In addition, where required by the authority having jurisdiction,
the installation must conform to American Society of Mechanical
Engineer
s Saf
ety Code for Controls and Safety Devices for
Automatically Fired Boilers, No. CSD-1.
This manual must be left with owner and should be hung on or
adjacent to the boiler for reference.
WARNING
This boiler
, gas piping and accessories must be installed, con-
nected, 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.
