INSTALLATION INSTRUCTIONS
LIQUEFIED PETROLEUM (L.P.)
PROPANE GAS-FIRED BOILERS
Installation location ONLY as permitted in paragraph enti-
tled "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. 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. If there
is any conflict in the above requirements, then the more
stringent requirement will apply.
This manual must be left with owner and should be hung
on or adjacent to the boiler for reference.
This boiler, gas piping and accessories must be installed,
connected, serviced and repaired by a trained, experi-
enced service technician, familiar with all precautions
required for gas-fired equipment and licensed otherwise
qualified, in compliance with the authority having jurisdic-
tion.
