PROPANE GAS-FIRED BOILERS
Installation location ONLY as permitted in paragraph entitled
"LIQUEFIED PETROLEUM (L.P .) PROPANE GAS-FIRED
BOILER LOCATION" on page 4 of this instruction book.
The above warning does not apply to NATURAL gas-
fired boilers.
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
propane
. The installation must also conform to the
additional requirements in this Slant/Fin Instruction Book.
In addition, where required by the authority having jurisdic-
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

This manual must be left with owner and should be hung on
or adjacent to the boiler for reference.
