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 during the construction process.

BOILERS FOR USE AT HIGH ALTITUDE
This 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 orifice size.
U.S.A. Only -
For altitudes above 2,000 feet above
sea level, input ratings should be reduced at the rate
These boilers must stand on a noncombustible floor.
If installed on a combustible floor, please refer to the
Repair Parts section in the back of this manual for the
appropriate Combustible Floor Base part number.
These Gas-Fired Hot Water Boilers are low pressure,
sectional cast iron boilers Design Certified by CSA
(Canadian Standards Association) for use with Natural
and Propane Gases. They are constructed and
hydrostatically tested for a maximum working pressure
of 50psi (pounds per square inch) in accordance with
A.S.M.E. (American Society of Mechanical Engineers)
Boiler and Pressure Vessel Code Section IV Standards
for cast iron heating boilers.
of 4% for each 1,000 feet above sea level. Consult the
National Fuel Gas Code (NFPA54/ANSI Z223.1-latest
revision), or the manufacturer for correct orifice sizing
information. High altitude orifices are available from
the boiler manufacturer.
Canada Only -
For altitudes in the range of 2,000-4,500
feet above sea level, boilers may be field equipped for use
at high altitude by using a certified field conversion kit. The
change in main burner orifice size results in the boiler’s
input rating being reduced by 10%.The conversion shall be
carried out by a manufacturer’s authorized representative,
in accordance with the requirements of the manufacturer,
provincial or territorial authorities having jurisdiction and
in accordance with the requirements of the CSA-B149.1
and CSA-B149.2 Installation Codes. The certified field
conversion kit includes a conversion data plate, which
must be attached to the boiler adjacent to the rating
plate, indicating that the boiler has been converted for
high altitude use. The conversion data plate must be
filled in with the correct conversion information.
Airborne particulates such as from drywall dust and
from fiberglass 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.
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 revision.
In Canada, the boiler shall be installed according to
CSA-B149.1 and .2, Installation Code for Gas Burning
Appliances and Equipment.
