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 juris- diction.

Combustion/Ventilation Air

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, drycleaning 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 the latest edition of the National Fuel Gas Code, ANSI Z223.1, or applicable provi- sions of the local building codes.

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 shown in Table C.

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.

5.3.5of the latest edition of the National Fuel Gas Code for additional requirements.

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 shown in Table D.
