See 5.3.3-b.

3.When communicating with the outdoors through hori- zontal ducts, each opening shall have a minimum free area of 1 square inch per 2,000 BTU per hour of total input rating of all equipment in the enclosure. (Figure 4)

5.3.5 Louvers and Grilles:

In calculating free area in 5.3.3, consideration shall be given to the blocking effect of louvers, grilles or screens protecting openings. Screens used shall not be smaller than 1/4 inch mesh. If the area through a design of louver or grille is known, it should be used in calculating the size of opening required to provide the free area specified. If the design and free area is not known, it may be assumed that wood louvers will have 20-25 percent free area and metal louvers and grilles will have 60-75 percent free area. Louvers and grilles shall be fixed in the open position or interlocked with the equipment so that they are opened automatically during equipment operation.

5.3.6Special Conditions Created by Mechanical Ex- hausting or Fireplaces:

Operation of exhaust fans, ventilation systems, clothes dryers, or fireplaces may create conditions requiring spe- cial attention to avoid unsatisfactory operation of installed gas utilization equipment.

IV. Category I Venting (Vertical Venting)

WARNING

To prevent possible death or personal injury due to asphyxiation, Amana Non- Condensing Gas Fired Warm Air Furnaces must be Category I vented. Do not vent any of these furnaces using Category III venting.

*If the appliance room is located against an outside wall and the air openings communicate directly with the outdoors, each opening shall have a free area of not less than one square inch per 4,000 BTU per hour of the total input rating of all appliances in the enclosure.

4.When ducts are used, they shall be of the same cross- sectional area as the free area of the openings to which they connect. The minimum dimension of rectangular air ducts shall not be less than 3 inches.

5.3.4 Specially Engineered Installations:

The requirements of 5.3.3 shall not necessarily govern when special engineering, approved by the authority hav- ing jurisdiction, provides an adequate supply of air for combustion, ventilation, and dilution of flue gases.

Category I Venting is venting at a non-positive pressure. A furnace vented as Category I is considered a fan-assisted appliance and does not have to be “gas tight.” NOTE: Single stage gas furnaces with induced draft blowers draw products of combustion through a heat exchanger allowing in some instances common venting with natural draft appli- ances (i.e. water heaters).

All installations must be vented in accordance with National Fuel Gas Code, NFPA 54/ANSI Z223.1 - latest edition. In Canada, the furnaces must be vented in accordance with the National Standard of Canada, CAN/CGA B149.1 and .2 - latest editions and amendments.

NOTE: The vertical height of the Category I venting system must be at least as great as the horizontal length of the venting system.

WARNING

To prevent possible death or personal injury due to asphyxiation, common venting with other manufacturer’s induced draft appliances is not allowed.

Common venting with specific Amana Category I 80% furnaces is allowed with the addition of a common vent kit (CVK) for each appliance. Contact the local installing dealer, distributor or Amana directly for more information.
