WARNING

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.

WARNING

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.
