U.S.A. Only - For altitudes above 2,000 feet, ratings should be reduced at the rate of 4% for each 1,000 feet above sea level. Canada Only - Boilers may be used at high altitude by using a certified field conversion kit, resulting in a 10% derate + Heating Capacity based on D O E. (Department of Energy) test procedure Add 5Va' to height when vent damper is used. t 2 Section boilers are equipped with a 3‘ diameter flue collar the furnished 4' vent damper. New York City MEA Number 63-91-E The Ratings marked “Net l=B=R Ratings” indicate the amount of equivalent direct radiation each boiler will take care of under normal conditions and thermostatic control. The Net l=B=R Ratings shown are based on an allowance of 1.15 in accordance with the factors shown on the l=B=R Standard as published by The Hydronics Institute. Selection of boiler size should be based upon "Net l=B=R Rating” being equal to or greater than the calculated heat loss of the building. The manufacturer should be consulted before selecting a boiler for installations having unusual piping and pickup requirements. These boilers must stand on a non-combustible floor. If installed on a combustible floor, use Combustible Floor Base Number 42135-1 or 146-14-031 (2-6 section boilers) or 42135-2 or 146-14-032 (7-9 section boilers). 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. the draft diverter, and use a furnished 3’x4' increaser fitting to install 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 sea level. Consult'the National Fuel Gas Code (NFPA54/ANSI Z223.1-latest edition), 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 indudes 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. 701020 2 Before You Start 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. You must see 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 venting system and an adequate piping sys...
