PERFORMANCE RATINGS ARE THE SAME FOR BOTH FUELS. 3 III Before Installing 1) Safe, reliable operation of this boiler depends upon installation by a professional heating contractor in strict accordance with this manual and the authority having jurisdiction. • In the absence of an authority having jurisdiction, installation must be in accordance with this manual and the National Fuel Gas Code, ANSI Z223.1. • Where required by the authority having jurisdiction, this installation must conform to the Standard for Controls and Safety Devices for Automatically Fired Boilers (ANSI/ASME CSD-1). 2) CHG boilers utilize aluminum heat exchangers constructed, tested, and stamped in accordance with ASME Boiler and Pressure Vessel Code Case 2382-2. Some jurisdictions which require ASME boiler construction do not recognize this Code Case and may not approve the installation of an aluminum boiler. Consult the authority having jurisdiction before installing this boiler. 3) Read Section VI to verify that the maximum combustion air and exhaust pipe lengths will not be exceeded in the planned installation. Also verify that the vent terminal is installed in the proper location. 4) Make sure that the boiler is correctly sized: • For heating systems employing convection radiation (baseboard or radiators), use an industry accepted sizing method such as the I=B=R Heat Loss Calculation Guide (Pub. #H21 or #H22) published by the Hydronics Institute in Berkeley Heights, NJ. • For new radiant heating systems, refer to the radiant tubing manufacturer’s boiler sizing guidelines. • For systems including an Alliance™ indirect water heater, size the boiler to ha...
