READ ALL OF THE FOLLOWING WARNINGS
AND STATEMENTS BEFORE READING THE
INSTALLATION INSTRUCTIONS
WARNING
LIQUEFIED PETROLEUM (L.P .)
PROPANE FIRED GAS 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 above warning does not apply to NATURAL gas fired
boilers.
NOTICE: INSTALLATION AND SERVICE MUST BE PERFORMED BY A
TRAINED AND QUALIFIED TECHNICIAN.
The installation must conform to the requirements of the
National Fuel Gas Code ANSI Z223.1 or the CSA B149.1-00
for natural gas and propane and the requirements of the
authority having jurisdiction as well as the requirements in
this instruction manual. In addition, where required by the
authority having jurisdiction, installation must conform to the
Standard for Controls and Safety Devices for Automatically
Fired Boilers, ANSI/ASME CSD-1 or the CSA B149.1-00 for
natural gas and propane. If there is any conflict in the above
requirements, then the more stringent requirement will apply.
WARNING
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, hung on or
adjacent to the boiler. Owner should retain manual
for future reference.
