Similar type vent dampers made by other manufacturers, and design certified by a nationally-recognized testing agency, under the ANSI Z21.66 standards, may also be used. Follow the installation instructions furnished with the vent damper package. The plug-in connector can also be used with power venters. Refer to the specific installation instructions supplied by the power vent manufacturer. SPECIFICATIONS AND DIMENSIONS Fig. #8978.1 3 3. INSTALLATION PROCEDURES CODE REQUIREMENTS Installation must be in accordance with local codes in the absence of local codes, with the latest editions of the National Fuel Gas Code, ANSI Z223.1, and the National Electrical Code,ANSI/NFPA 70. In Canada, installations must conform with the current CAN/CGA B149.1 or .2 and the Canadian Electrical Code Part 1 CSA C22.2 No.1. Where required by the authority having jurisdiction, the installation must conform to American Society of Mechanical Engineers Safety Code for Controls and Safety Devices for Automatically Fired Boilers, CSD-1. MOUNTING BASE Boiler should be mounted on a level surface. Each boiler is designed with a built-in sub-base approved for mounting the boiler on combustible flooring. Boiler must NOT be installed on carpet flooring. CLEARANCE REQUIREMENTS 1) Minimum Clearances From Combustible Materials Model No. Floor Front Back Right Left Top Flue Vent 0042 0066 0090 Comb. 4" 6" 6" 6" 16" 6" 0135 0180 Comb. Alcove 6" 6" 6" 16" 6" 2) A front clearance of at least 24" is recommended for adequate service of burner-tray and controls. 3) Except for carpeted flooring, boilers are certified for installation on combustible floors. 4) For un-insulated hot water pipes, maintain a 2" clearance, or consult local authority having jurisdiction. COMBUSTION/VENTILATION AIR Fig.# 8196 NOTE: The boiler should be located in an area where water leakage will not result in damage to the area adjacent to the appliance or to the structure. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the appliance. The pan must not restrict air flow. In addition, the boiler shall be installed such that the gas ignition system components are protected from water (dripping, spraying, rain, etc.) during appliance operation and service (circulator replacement, control replacement, etc.) WARNING: Air supply to the boiler room must not be affected by mechanical exhaust vents located in other parts of the house, such as kitchen or bathroom fans, or attic blowers. Mechanical exhaust vents may create a negative pressure condition in the boiler room that can become a hazard of asphyxiation, explosion or fire. CAUTION: Combustion air must not be contaminated by corrosive chemical fumes which can damage the boiler. Measures must be taken to prevent the entry of corrosive chemical fumes to the combustion and ventilation air supply. Such chemicals include, but are not limited to, chlorinated and/or fluorinated hydrocarbons such as found in refrigerants, aerosol propellants, dry- cleaning fluids, degreasers, and paint removers. Other harmful elements may come from bleaches, air fresheners, or mastics. Vapors from these types of products can form corrosive acid compounds when burned in a gas flame. The resulting acid condensate can damage or substantially reduce the life of the heater. It may be necessary to provide outside air directly to the heater in order to avoid this problem. 1) The boiler must be provided with adequate supply of air for proper combustion and ventilation in accordance with Sec. 5.3, of the latest edition of the National Fuel Gas Code, ANSI Z223.1, or applicable provisions of the local building codes. 4 2) Models 0042 and 0066 only- When the boiler is installed in a confined space such as a utility room or closet where all air is supplied from inside the building, the boiler room must be provided with two openings, each one having a minimum net free area, in square inches as follows: Model Sq. In. of Free Area 0042, 0066 70 One opening shall be within 12" of the top, and the other opening within 12" of the floor. If additional gas appliances are installed in the same space, the total input of all gas appliances installed in the same space, must be considered in the calculation. Refer to Sec. 5.3.5 of the latest edition of the National Fuel Gas Code for additional requirements. Fig.# 8198.0 NOTE:If louvers, grills or screens are used on the openings, obtain the net free area requirements from their supplier or manufacturer. If the design free area of a louver is not known nor available, it shall be assumed that wood louvers will have 20-25 percent free area and metal louvers will have 60-75 percent free area as shown in Sec. 5.3.5 National Fuel Gas Code. 3) If the boiler room is located against an outside wall and air openings can communicate directly with the outdoors, the two openings on the outside wall must each have a net free area as follows: Model (Sq. In.) Net Free A...
