EXPLANATORY NOTES
• This boiler cannot be used with all types of chimneys. Read these instructions carefully before installing.
• These Gas-Fired Hot Water Boilers are low pressure, sectional cast iron boilers Design Certified by C.S.A. (Canadian
Standards Association) for use with Natural and Propane Gases.
• Constructed and hydrostatically tested for maximum working pressure of 50 psi in accordance with A.S.M.E. Boiler
and Pressure Vessel Code Section IV Standards for cast iron heating boilers.
• Boilers must stand on noncombustible floor. If installed on combustible floor, please refer to (Combustible Floor
Addendum) included in literature envelope provide with boiler and outlined in National Fuel Gas Code, ANSI Z223.1/
NFPA 54.
• The MEA number for this boiler is 484-84-E Vol� IV�
(1) Input rating for sea level to 2,000 feet. (610 m) above sea level.
(2) Net AHRI Water Ratings shown
selecting boiler for installations having unusual piping and pickup requirements, such as intermittent system
operation, extensive piping systems, etc.
For forced hot water systems where boiler and all piping are within area to be heated, boiler may be selected
on basis of its heating capacity.
Boilers For Use At High Altitude
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, reduced input rate 4% for every 1,000 feet above sea level.
U�S�A� Only - For altitudes above 2,000 feet above sea level, input ratings should be reduced at rate of 4% for each
1,000 feet above sea level. Consult National Fuel Gas Code (NFPA54/ANSI Z223.1), or manufacturer for correct orifice
sizing information. High altitude orifices are available from boiler manufacturer.
