INTRODUCTION This appliance is a gas-fired direct vent hot water boiler with cast aluminum boiler sections. A revolutionary cast aluminum heat exchanger means better heat transfer and thermal storage than similarly sized cast iron boilers, which results in higher efficiency. The heating system water absorbs large amounts of heat from the cast aluminum heat exchanger, cooling the flue gases and causing condensation.

BOILERS FOR USE AT HIGH ALTITUDE The boilers are factory equipped for operation at altitudes ranging from 0-2,000 feet above sea level. For use of these boilers at altitudes above 2,000 feet above sea level, the gas input ratings (MBH) must be reduced. certified high altitude conversion kit. The change in main burner orifice size results in a 10% reduction of the boiler gas input rating (MBH). The conversion shall be carried out by a manufacturer’s authorized representative, U.S.A.

RULES FOR SAFE INSTALLATION AND OPERATION l. Read the entire installation manual before beginning the installation. Failure to follow these rules for safe installation and operation and these instructions could cause a malfunction of the boiler and result in death, serious bodily injury, and/or property damage. 2. Check all applicable state and local building codes and utility company requirements before installation. The installation must conform with these requirements in their entirety.
BEFORE INSTALLING THE BOILER Continued 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. Installers - Follow local regulations with respect to installation of CO (Carbon Monoxide) Detectors. Follow maintenance recommendations in this manual.

BEFORE INSTALLING THE BOILER Continued ! CAUTION ! KEEP BOILER AREA CLEAN OF DEBRIS AND FREE OF FLAMABLE AND COMBUSTIBLE MATERIALS, VAPORS AND LIQUIDS ! WARNING ! When vent pipe is exposed to temperatures below freezing, such as when it passes through an unheated space or when a chimney is used as a raceway, vent pipe must be insulated with 1/2” Armaflex or equivalent. In extreme cold climate areas, use ¾” Armaflex or equivalent. Combustion air must be clean outdoor air.
BEFORE INSTALLING THE BOILER Continued G. FOUNDATION REQUIREMENTS 4. Place in operation the appliance being inspected. Follow the lighting instructions. Adjust thermostat so appliances will operate continuously. Boiler must be placed on level surface. Boiler is NOT to be installed on carpeting. NOTE: 1. If boiler is not level condensate drain lines will not function properly. Adjustable feet are located on the boiler to make up for minor surface irregularities or tilt. 2.
NEAR BOILER PIPING ! CAUTION ! Copper supply and return piping. must NOT be installed directly into aluminum boiler section casings due to galvanic corrosion between dissimilar metals. Iron or steel bushings or pipe nipples should be used between copper system piping and boiler to make final connection to boiler. Also, the use of dielectric unions is acceptable. The packaged boiler is furnished with iron piping in the front boiler section for the supply and return connections. boiler.

MAINTENANCE AND CLEANING Maintenance as outlined below can be performed by the owner unless otherwise noted. The acidic nature of flue gasses condensing on the aluminum boiler sections will cause the formation of aluminum oxide. This oxide formation is normal, is generally uniform throughout the boiler sections, and represents a negligible mass of aluminum that is consumed by oxidation during the life of the boiler.
MAINTENANCE AND CLEANING C. MONTHLY DURING HEATING SEASON 1. Remove jacket front and top panels and check for piping leaks around relief valve and other fittings. If found, contact a qualified service agency to repair. DO NOT use stop leak compounds. 2. Test relief valve. Refer to valve manufacturers instructions packaged with relief valve. 2. If heating system is to remain out of service during freezing weather, and does not contain antifreeze, drain system completely.
MAINTENANCE AND CLEANING c. Remove air baffle from 1% z” x 2” flexible cou- l. Connect: pling and clean air baffle if necessary. Refer • gas line to gas valve to repair parts diagram, mixer and pressure • condensate drain line to boiler switch assembly. • pressure switch hose to gas valve • air by-pass to mixer d. Confirm that manual gas valve is closed and • 1 ½” x 2” flexible coupling to air inlet and disconnect gas line to gas valve at union. Disconnect wires to gas valve. and igniter.
MAINTENANCE AND CLEANING d. Reinstall and connect the condensate trap, using the hose clamps to secure the various condensate lines to their fittings. e. Follow the instructions under “NEAR BOILER PIPING” for”filling condensate trap with water” 4. Inspection of the flue connector requires the following steps (Refer to the repair parts diagram.) a. Loosen the clamp on the draft inducer end of the 2” flexible coupling that connects the vent tee to the draft inducer.
