FOR COMBUSTION Before you begin installing furnace, pian to provide enough combustion and ventiiation air following: — — Current National Fuel Gas Code ANSI Z223.1/NFPA 54, Section 5; Local Code authorities. Refer to Section 31 of this manual for these codes.
WARNINO: Combustion and vsntllatlon air that contains chlorine, fluorine, bromine and Iodine could cause heat exchanger or vent system failure, resulting In damage, Injury or death, If ratio is less than 50, installation space is a con fined space. If ratio is 50 or greater, installation space is an unconfined space. B. Installing furnace In confined space.

Refer to current National Fuel Gas Code ANSI Z223.1/NFPA 54. 5. if combustion air ducts will run horizontally, ducts and each opening must have a minimum free area of one square inch per 2,000 Btuh total combined input rating. You must allow for all gas appliances within the furnace space. See Figure 14. Example: Furnace is 100,000 Btuh input and is to be installed in a confined space that contains no other gas appliances.
SICTION 9 — PROVIDING P with louvvrs or grilles closed could cause Inadequate combustion or ventilation air, resulting In Injury or death. C. INTING. Vent furnace using these instructions and Venting Adden dum. Also, meet requirements of local utilities and other local code authorities. You must connect furnace to a vent or fac tory-built chimney or a suitably sized, constructed and lined masonry chimney. Vent or factory-built chimney must meet a recognized standard.
C. Design considerations. 1. b. Use Type B1 vent connectors in or through at tics, crawl spaces, or other cold areas. Install thimbles that meet local codes when vent con nectors pass through walls or partitions of com bustible material. c. Keep vent connectors as short as possible by locating furnace as dose as practical to vent or chimney. Avoid unnecessary turns or bends which create resistance to flow of vent gases. General considerations. Avoid oversizing furnace for your application.
OT evidence of condensate exists, consider using chimney as a pathway for suitably sized Type B1 vent liner. See Figure 15. NOTE; For more information on proper chimney in spection and relining procedures, Gas Research In stitute (GRI) has a topical report entitled "Masonry Chimney Inspection and Reiintng". Obtain copies through American Gas Association (A.G.A.) at 1-800-841-8400. 6. Vent termination. a.

GAMA VENTING TABLES FOR CATEGORY I CENTRAL FURNACES This booklet contains new venting tables designed specifically for use with Category I central furnaces. These tables are unique, in that, industry wide venting tables now exist for fan-assisted combustion system central furnaces. Venting tables for these types of appliances are not contained in the National Fuel Gas Code (NFPA 54/ANSI Z223.1-1988).
VENTING REQUIREMENTS FOR CATEGORY I APPLIANCES INTRODUCTION This booklet contains the current definitions, instructions, and tables necessary to vent todays modern Category I Gas Fired Appliance. A variety of definitions of new terms describing today's gas appliances are included to supplement the actual venting tables which have been generated to correctly vent various combinations of Category I Appliances using Type B or single*wall metal vent connectors attached to Type B vents or masonry chimneys.
) ) I. GENERAL VENTING REQUIREMENTS 3) All requirements contained in this document apply to both Category 1 draft hood equipped and fanassisted combustion appliances. At no time should a venting system for a listed Category 11, 111, or IV appliance be sized with these Tables. The alternate sizing methods described in the National Fuel Gas Code (NFPA54;aNS1 Z223.V1988) may also be used to size the venting system for a drafthood equipped appliance.
GAS VENT TERMINATION TABLE b. The minimum capacity (Fan Min.) shaH be determined by referring to the corresponding single appliance table (Tables 1 and 2). In this case, for each appliance the entire vent connector and common vent from the appliance to the vent termination would be treated as a single appliance vent, as if the other appliances were not present.
10) No portion of the venting system can extend into, or pass through any circulating air duct or plenum. 11) All vent pipe passing through floors, walls, and ceilings must be installed with the listed clearance to combustible materials and be fire stopped according to local codes. In the absence of local codes, refer to NFGC (2223.
22) 23) Listed, corrugated metallic chimney liner systems in masonry chimneys shall be sized by using Tables 1 or 2 tor dedicated venting and Tables 3 or 4 for common venting with the maximum capacity reduced by 0.20% (0.80 X maximum capacity) and the minimum capacity as shown in the applicable table. Corrugated metal vent systems installed with bends or offsets require additional reduction of the vent maximum capacity (See Note 6).
Tabi* 3 should be used when Type 6 vent connectors are attached to a Type В common vent. Table 4 should be used when single-wall metal vent connectors are attached to a Type В common vent.

EXAMPLES USING SINGLE APPLIANCE VENTING TABLES Example 1; Single Draft-Hood-Equipped Appliance Suppose that an installer has a 120,000 8tu/hr input apptiafx:e with a 5 inch diameter draft hood outlet that needs to be vented into a 10 foot high Type В vent system.
EXAMPLES USING COMMON VENTING TABLES Example 3: Common Venting Two Draft-Hood Appliances Example 4; Common Verting a Draft Hood Water Suppose a 35,000 Btu/hr water heater is to be сотгтюп vented with a 150,000 Btu/hr furnace using a common vent with a total height of 30 feet. The connector rise is 2 feet for the water heater and 3 feet for the furnace. Assume single-wall metal connectors will be used with Type В vent.
EXAMPLES USING COMMON VENTING TABLES Example 4; (cont'd) Common Vent Diameter. The total input to the common vent is 135,000 Btu/hr. Using Table 4, Common Vent Capacity, read down the Total Vent Height "H** column to 30 feet and across this row to find the smallest vent diameter in the "FAN+NAT column that has a Btu/hr rating equal to or greater thani 35,000 Btu/hr. The 4 inch common vent has a capacity of 132,000 Btu/hr and the 5 inch common vent has a capacity of 202,000 Btu/hr.
Example 7: Interpolating Between Table Values EXAMPLE 6: (cont'd) An installer has an 80,000 Btu/hr input appliance with a 4 inch diameter draft hood outlet that needs to be vented into a 12-ft high Type В vent.
