CONSULT LOCAL CODE OFFICIALS for ductwork design and performance requirements in your area. General Requirements The duct system should be designed and sized according to accepted national standards such as those published by: Air Conditioning Contractors Association (ACCA Manual D), Sheet Metal and Air Conditioning Contractors National Association (SMACNA) or American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) or consult The Air Systems Design Guidelines reference tables available from your local distributor. The duct system should be sized to handle the required system design CFM at the design external static pressure. The furnace airflow rates are provided in Table 9—Air Delivery—CFM (With Filter). When a furnace is installed so that the supply ducts carry air circulated by the furnace to areas outside the space containing the furnace, the return air shall also be handled by duct(s) sealed to the furnace casing and terminating outside the space containing the furnace. Secure ductwork with proper fasteners for type of ductwork used. Seal supply— and return—duct connections to furnace with code approved tape or duct sealer. NOTE: Flexible connections should be used between ductwork and furnace to prevent transmission of vibration. Ductwork passing through unconditioned space should be insulated to enhance system performance.When air conditioning is used,a vapor barrier is recommended. Maintain a 1—in.(25 mm)clearance from combustible materials to supply air ductwork for a distance of 36—in.(914 mm)horizontally from the furnace. See NFPA 90B or local code for further requirements. Return Duct Sizing Refer to the Filter Selection and Duct Sizing section for information on the proper selection of filter sizes and the associated ductwork and duct transitions. Improperly designed filtering systems and return ductwork are the most common causes of airflow and/or noise complaints in HVAC systems. Ductwork Acoustical Treatment NOTE: Metal duct systems that do not have a 90 degree elbow and 10 ft. (3 M) of main duct to the first branch take—off may require internal acoustical lining. As an alternative, fibrous ductwork may be used if constructed and installed in accordance with the latest edition of SMACNA construction standard on fibrous glass ducts. Both acoustical lining and fibrous ductwork shall comply with NFPA 90B as tested by UL Standard 181 for Class 1 Rigid air ducts. NOTE: For horizontal applications, the top most flange may be bent past 90' to allow the evaporator coil to hang on the flange temporarily while the remaining attachment and sealing of the coil are performed. 31 Table 9—Cooling4 and Heating Air Delivery—CFM(Bottom Returns with Filter) (SW1-5 and SW2-2 set to OFF,except as indicated.See notes 1 and 2) Unit Size Cooling Switch Settings External

See Fig. 12. Use a flat blade screwdriver and tap on the knockout on opposite sides, where the knockout meets the casing. Fold the knockout down with duct pliers and work the knockout back and forth until it is removed. Trim any excess metal from the knockout with tin snips. The vent elbow can be rotated to the required location on the casing if necessary.See Fig.41.To rotate the vent elbow: 1. Loosen the clamp on the inlet of the vent elbow attached to the inducer. 2. Rotate the vent elbow to the required position. There are rounded notches on the vent elbow to align it with the inducer housing for each orientation. 48 Table 13-Hanger Spacing Material Diameter PVC Sch 40 SDR 21 &26 ABS CPVC Polypropylene 1 1/2-in. 3-ft. 2 1/2-ft. 3-ft. 3-ft. 3.25-ft. 38-mm 914-mm 762-mm 914-mm 914-mm 1000 mm 2-in. 3-ft. 3-ft. 3-ft. 3-ft. 3.25-ft. 51-mm 914-mm 914-mm 914-mm 914-mm 1000 mm 2 1/2-in. 3 1/2-ft. 3-ft. 3 1/2-ft. 3 1/2-ft. 3.25-ft. 64-mm 1067-mm 914-mm 1067-mm 1067-mm 1000 mm 3-in. 3 1/2-ft. 3-ft. 3 1/2-ft. 3 1/2-ft. 3.25-ft. 76-mm 1067-mm 914-mm 1067-mm 1067-mm 1000 mm 4-in. 4-ft. 3 1/2-ft. 4-ft. 4-ft. 3.25-ft. 4.

Use only the smallest diameter pipe possible for venting. Over-sizing may cause flame disturbance or excessive vent terminal icing or freeze-up. 2. NA-Not allowed. Pressure switch will not close,or flame disturbance may result. 3. Vent sizing for Canadian installations over 4500 ft.(1370 M)above sea level are subject to acceptance by the local authorities having jurisdiction. 4. Size both the combustion air and vent pipe independently,then use the larger size for both pipes. 5. Assume the two 45°elbows equal one 90°elbow. Wide radius elbows are desirable and may be required in some cases. 6. Elbow and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count. 7. The minimum pipe length is 5 ft.(2 M)linear feet(meters)for all applications. 8. Use 3-in.(76 mm)diameter vent termination kit for installations requiring 4-in.(102 mm)diameter pipe. 53 Venting System Length Calculations The Total Equivalent Vent Length(TEVL)for EACH combustion air or vent pipe equals the length of the venting system,plus the equivalent length of elbows used in the venting system from Table 17. Standard vent terminations or factory accessory concentric vent terminations count for zero deduction. See vent system manufacturer's data for equivalent lengths of flexible vent pipe or other termination systems. DO NOT ASSUME that one foot of flexible vent pipe equals one foot of straight PVC/ABS DWV vent pipe. Compare the Total Equivalent Vent Length to the Maximum Equivalent Vent Lengths in Table 16. Example 1 A direct-vent 60,000 BTUH furnace installed at 2100 ft.(640M).Venting system includes FOR EACH PIPE: 70 feet(22 M)of vent pipe,65 feet(20 M)of combustion air inlet pipe,(3)90°long-radius elbows,(2)45'long-radius elbows,and a factory accessory concentric vent kit.

In most cases,only 1 method should be used to achieve TDR function.Using more than 1 method in a system may cause degradation in performance. Use either the accessory Time—Delay Relay KAATD0101TDR or a furnace equipped with TDR.Most Carrier furnaces are equipped with TDR. NOTES: 1. Ratings are net values reflecting the effects of circulating fan motor heat.Supplemental electric heat is not included. 2.Tested outdoor/indoor combinations have been tested in accordance with DOE test procedures for central air conditioners.Ratings for other combinations are determined under DOE computer simulation procedures. 3.Determine actual CFM values obtainable for your system by referring to fan performance data in fan coil or furnace coil literature. 4.Do not apply with capillary tube coils as performance and reliability are significantly affected. 12 N K n n n n 0 0 0 0 M M M M W d K (O N N N O m m m M M M M C N� ao ao ao ao m ao ao ao m m m m F y Y N N N N N N N N N N N N F N Y N N N N N N N N N N N N n n L M M O O m M N N a L N M N N N M (O(O N 7 7 � � No��N N 1-n W V N N N m N M O M M M 7 M M OA N 7 7 N m N O M n n 7 n n N 6 ,6 T C. 7(O O O O M N N m N p_ N m(O(O 7 (O(O n a0 7 7 W « (O N 7 7 00 7 00 00 00 N N N (O �W„ N M n V(O N N U F N 7 M M N 7 M M N 7 7 7 U F O W n n 0 W n n O 0D OD OD GW d K aD n 7 7 d m m m m W Omi,Omi,Om co(O w O O Ni,O O O O C N N N N f0 f0 f0 f0 f0 f0 f0 f0 F N Y NNNN F N Y N N N N N N N N N N N N (p y a M m m m m O N o o (p N y a 7 7(O 7 7 m N N I-n N N N N V ? � �O N N 1-�O m W M m 7 V N m y m m !�2 N m N M M M M m m T T .0 ,U O_ m a0 a0 a0 m m (O O O p_ m a s N M 7 M N N W M 7 N N 0(O 1�n N n N N (O �W„ (O n N N m m m m . .a a U F N N 7 7 1�N 7 7 n N N N U F m W W m W W N O m m � �� � N N N N m E co co co co W W W W N N N N W 0Ef K N O O co N V 7 m m M M M M M M C N M M M M M M M M M M M M F y�[ —————————— F No Y N N N N N N N N N N N N LL b LL p N M n M M N(O m m �+ O L C Q(O O 0 N CO CO O m 0 0 a m W co N(m`),N N IN m m 00 IN IN N m G m N m �2!m !�2!�2 0� (O (O W G m N 7 n m N N m m N N N N ¢ @ m W a N'nNmMMo(Om m W w a W oa LU NMM o oNnmm MNON(OCOCO *0DOo N N N w V2 N M(O N N M(O(O (O W U N N N N N N N N F F Q Q Z N - MOD OD OD W V V V Z ad) ronnn W (R�2 m N N N N f0 f0 f0 f0 f0 f0(O (O O O O O FF N y - —————————— H N Y N N N N N N N N N N N N 2 ~ W Z W ¢ S w M Lm (O/1) Mm 0Om MVN VVWWN vpNj m m • On ma0 OnD'nO o N g m n M NZ C �O m N cl NNO�2(O (O W a0 O r U 'u U W V N 7 m' 0m o N m n m m (�O « O Q O a0 M�7 N W m m W W V N M I-CO m m 0 OD N N U F m r(O(n m (O N m N N O w 3 v v v v v v v v v v v v m m m m--m m--- - Vl a m L N a O 7 N M m(N n m L M N M M 7 N O 00 7 M N N C N v C N 7 M m m 6 I�00 n V N N aj V(O m f/) N N N vi N N N m (d N/1 OO U d O_ a m m N m a0 N' O O O O. m 0 0 m� N 7 �M M W O M OD N M(O N (O m I� n W W (O a s m a0 m OD V N N N N N N W N U H W O2 U F N M 0 N M N 7 N N N N N N N N N N N N N N uEl* nnnnm000N M M M W y OD n(O(ON O O(ON V V ryl N N N N N M M M M M M M F N Y F TC u?---n n n n n n n n yY U _ _ I M N(O n o n M n N N +F v M L W N c OD (D MmOD O M maDnnNaO n aoaa d O—a-O-----0 0 n m N N N W N�2 N N p N N N m (A � n � .d G O _ N n M(O O M n N(O(O N O W W O O O N(O V O OD(O mM V 06 06 m Fjp OmD n1m�MN m(O m7 nO MO VN V U m M n N N N N N N N N N N N N U A N 7 T N 7 T N 7 T N 7 rn N 7 T N 7 rn Vo oM 14 oM 14 oM G mU vOi ro M C"M oM Vo oM w LL N n N n N n N n N n N n cc w LL N n N n N n N n N n N n 01 O n(O(O N n(O(O N n(O(O N O n(O(O N n(O(O N n(O(O m O- ¢ Q 0 O cc Fa a Y W w U N w W U n Acf) 13 W W k m M n n V W N N M n n n W W K n N W W M O O m n M M �z 7 7 7 V N N N N N N N N Z N N N N M M M M M M M M h N Y M M M M M M M M M M M M h N Y a a a a a a a a a a a a n n *F M M M M M N N v o M M M *F a N N 0) M a M m M M C V V O O N n M M 0 m m M m v C O 1-N N m N O O n 10 M f0 M W 7 M N N N m N N M O W n M M n M n n M n �NNN�N N N N W _ W _ O. m O M M n m N N l0 M M O.
