CONTAMINATION PREVENTION
The combustion air supply must not be susceptible to contami- nation sources, whether the combustion air comes from the interior or exterior of the building. Contaminated air can cause corrosion or other damage to the heat exchanger and compo- nents of the boiler, causing failure of these parts or unsafe operation.
Below is a list of products and areas which may cause contaminated combustion air:
PRODUCTS TO AVOID
•Spray cans containing chloro/fluorocarbons
•Permanent wave solutions
•Chlorinated waxes/cleaners
•
•Calcium chloride used for thawing
•Sodium chloride used for water softening
•Refrigerant leaks
•Paint or varnish removers
•Hydrochloric acid/muriatic acid
•Cements and glues
•Antistatic fabric softeners used in clothes dryers
•
•Adhesives used to fasten building products and other similar products
AREAS LIKELY TO HAVE CONTAMINANTS
•Dry cleaning/laundry areas and establishments
•Swimming pools
•Metal fabrication plants
•Beauty shops
•Refrigeration repair shops
•Photo processing plants
•Auto body shops
•Plastic manufacturing plants
•Furniture refinishing areas and establishments
•New building construction
•Remodeling areas
•Garages with workshops

BOILER ROOM AIR SUPPLY AND VENTILATION
An ample supply of air is required for combustion and ventila- tion. When buildings are insulated, caulked and weather- stripped, now or later on, direct openings to outside may be required and should be provided. If the boiler is not near an outside wall, air may be ducted to it from outside wall openings.
Provisions for combustion and ventilation air must be made in accordance with section 5.3, Air for Combustion and Ventila- tion, of the National Fuel Gas Code, ANSI
INSTALLATION IN ENCLOSED BOILER ROOM REQUIRES TWO UNOBSTRUCTED OPENINGS FOR PASSAGE OF AIR INTO THE BOILER ROOM.
A. NON-DIRECT VENT INSTALLATION
1.Air drawn horizontally from outdoors DIRECTLY through an outside wall; one louvered opening near the floor and one louvered opening near the ceiling, each opening with a minimum FREE air passage area of 1 square inch per 4000 Btuh of total appliances’ input.
2.Air drawn horizontally through HORIZONTAL DUCTS; one opening near the floor and one opening near the ceil- ing, each opening with a minimum FREE air passage area of 1 square inch per 2000 Btuh of total appliances’ input.
3.Air drawn VERTICALLY from outdoors; one opening at the floor and one opening at the ceiling, each opening with a minimum FREE air passage area of 1 square inch per 4000 Btuh of total appliances’ input.
4.Air drawn from inside the building; one opening near the floor and one opening near the ceiling, each opening with a minimum FREE air passage area of 1 square inch per 1000 Btuh of total appliances’ input.
IF BOILERS ARE INSTALLED ADJACENT TO OTHER FUEL BURNING EQUIPMENT, THE AREA OF FREE OPENINGS MUST BE APPROPRIATELY INCREASED TO ACCOMMO- DATE THE ADDITIONAL LOAD.
B. DIRECT VENT INSTALLATION
Adequate air supply should be provided to prevent overheating of the boiler controls and boiler room. Openings for passage of air into the boiler room for
