Check to be sure you have the right size boiler before starting the
installation. See rating and capacity table on previous page. Also be
sure the new boiler is for the type of gas you are using. Check the
rating plate on the right side of the boiler.
Verify that the boiler is supplied with the correct type of gas, fresh air
for combustion, and a suitable electrical supply. Also, the boiler must
be connected to a suitable chimney or horizontal venting system and
an adequate piping system. Finally, a thermostat, properly located, is
needed for control of the heating system. If you have any doubts as
to the various requirements, check with local authorities and obtain
professional help where needed. Take the time to complete all of the
steps for SAFE and PROPER operation of the heating system.
If this boiler is installed in a building under construction, special
care must be taken to insure a clean combustion air supply dur-
ing the construction process. Airborne particulates such as from
drywall dust and from berglass insulation can clog the burner ports
and cause incomplete combustion and sooting. Where required by
the authority having jurisdiction, the installation must conform to
American Society of Mechanical Engineers Safety Code for Controls
and Safety Devices for Automatically Fired Boilers, No. CSD-1.
e 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 revision.
In Canada, the boiler shall be installed according to CSA-B149.1 and
.2, Installation Code for Gas Burning Appliances and Equipment.
Boilers For Use At High Altitude
is boiler is factory equipped for use at altitudes of 0-2,000 feet
above sea level. For use at altitudes above 2,000 feet above sea level,
the input ratings are reduced by a change in main burner orice size.
U.S.A. Only - For altitudes above 2,000 feet above sea level, input
ratings should be reduced at the rate of 4% for each 1,000 feet above
ese boilers must stand on a noncombustible oor. If installed on
a combustible oor, please refer to the Repair Parts manual for the
appropriate Combustible Floor Base part number.

manufacturer.
Canada Only - For altitudes in the range of 2,000-4,500 feet above
sea level, boilers may be eld equipped for use at high altitude by
using a certied eld conversion kit. e change in main burner
orice size results in the boiler’s input rating being reduced by 10%.
e conversion shall be carried out by a manufacturer’s authorized
representative, in accordance with the requirements of the manufac-
turer, provincial or territorial authorities having jurisdiction and in
accordance with the requirements of the CSA-B149.1 and CSA-
B149.2 Installation Codes. e certied eld conversion kit includes
a conversion data plate, which must be attached to the boiler adja-
cent to the rating plate, indicating that the boiler has been converted
for high altitude use. e conversion data plate must be lled in with
the correct conversion information.
NOTICE
Installers - Follow local regulations with respect to instal-
lation of CO detectors. Follow maintenance recommenda-
tions in this instruction manual.
NOTICE
Keep boiler area clean and free from combustible materi-
als, gasoline and other ammable vapors and liquids
