3. INSTALLATION PROCEDURES
CODE REQUIREMENTS
Installation must be in accordance with local codes, or, 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 con- form to American Society of Mechanical Engineers Safety Code for Controls and Safety Devices for Auto- matically Fired Boilers, No.
MOUNTING BASE
Boiler should be mounted on a level surface. Each boiler is designed with a
CARPET
Fig.# 8196.0p
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 in- stalled 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.)

3)Except for carpeted flooring, boilers are certified for installation on combustible floors.
4)For
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 ven- tilation 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 fresh- eners, 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 accor- dance with Sec. 5.3, of the latest edition of the National Fuel Gas Code, ANSI Z223.1, or appli- cable provisions of the local building codes.
