manual abstract
In the United States, follow all safety codes including the National Fuel Gas Code NFPA No. 54-1988/ANSI Z223.1-1988. Wear safety glasses and work gloves. Have fire extinguisher available during start-up and adjustment procedures and service calls. Recognize safety information. This is the safety-alert symbol ^ . When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury. Understand the signal word DANGER, WARNING, or CAUTION. These words are used with the safety-alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards that could result in personal injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. These instructions cover minimum requirements and conform to existing national standards and safety codes. In some instances, these instructions exceed certain local codes and ordinances, especially those that may not have kept up with changing residential construction practices. We require these instructions as a minimum for a safe installation. INTRODUCTION Model 61SW is a low-pressure, sectional, cast-iron water boiler. The design of model 61SW is certified by A.G.A. for use with natural and propane gases (model 61SWC with natural gas and 61SWE with propane gas). It is tested for a maximum working pressure of 50 psi on water in accordance with American Society of—Mechanical—Engineers-(A.S.M.E..)_Code—IV_Standards_for_ cast-iron boilers. It is to be installed indoors only. All boilers are factory assembled. lama © A.S.M.E. A85085 Fig. 1—Model 61SW-075100 Consult the local building codes or ordinances that may apply. INSTALLATION A CAUTION Do not install the boiler in a corrosive or contaminated "atmosphere. Make~sure_ all”combustion~and~circulating-air- “All installations are subject to codes established by locaFutilities or other authorities having jurisdiction. This jurisdiction normally covers electrical wiring, gas piping, flue specification, and insulation of adjacent combustible material where required clearances cannot be maintained. The installation must conform with the National Fuel Gas Code, NFPA No. 54-1988/ANSI Z223.1-1988. Where required by the authority having jurisdiction, the installation must conform to the American Society of Mechanical Engineers’ Safety Code for Controls and Safety Devices for Automatically Fired Boilers, No. CSD-1. requirements are adhered to, in addition to all local codes and ordinances. Do not use this boiler during construction when adhesives, "sealers, and/or new carpets are being installed-If-the-boiler-is-required during construction, use clean outside air for combustion and ventilation. Compounds of chlorine and fluorine when burned with combustion air form acidswKiclTwill cause corrosion of the sections and metal vent systems. Some of these compounds are found in paneling and dry wall adhesives, paints, thinners, masonry cleaning materials, and many other solvents commonly used in the construction process. Step 1—Location 1. The boiler must be installed on a level foundation. Metal shims may be used to level if required. Locate the boiler near a gas vent or a chimney. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Combustible floors-Do not install the boiler on carpeting. When the boiler is installed on a combustible floor, you must use a factory-supplied combustible floor installation kit containing a rectangular piece of insulation material. Position the insulation on the combustible floor and place the boiler on top of the insulation. 3. Alcove installation only — Maintain at least 6 in. from combustible material on the left-hand (LH) side, 6 in. from the back and 6 in. from the top. 4. Leave enough room for service access on the right-hand (RH) side and front. A minimum of 24 in. is required. A WARNING The boiler, when installed, must be electrically grounded in accordance with the National Electrical Code, ANSI/NFPA No, 70-1988.
