Piping with Street Elbows 1, Assemble the elbows so that the outlet of one(l) elbow is 90 ° from the inlet of the other. The elbows should be tight enough to be leak proof. An additional 1/4 turn will be required at the end of step 2, see Figure 13. iiiiiiiiiiiiiiiiiiiiiiiiiiiii_;!iiiiiiiiiiiiiiiiiiii!!iiiiii!!il;iiiiii!i .iiiii!!iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii;i;ii;!iiiiiiiiiii_i (_ 25-23-23c 2, Screw elbow assembly into gas valve far enough to be leak proof. Position el bow assembly so that the inlet of the el bow is at the top of the gas valve. An additional 3/8 turn will be re quired in step 3. Turn open end of inlet elbow to face the left side of the furnace (1/4 turn), see Figure 14. Gas Valve with Elbows (N8MP) 3. Turn assembly an additional 3/8 turn to position inlet near the bottom back corner of the gas valve in line with gas opening on left side of furnace, see Figure 15. 4. Gas supply line then can be run directly into opening of elbow. Piping with Close Nipples and Standard Elbows 1. Assemble elbows and nipples similar to street elbows shown in Figure 13. 2. Follow steps 2 through 4 Piping with Street Elbows. Gas Valve with Elbows (N8MP) 25-24-96a-2 FIRE HAZARD Failure to follow safety warnings exactly could result in death, personal injury and/or property damage. Use wrench to hold furnace gas control valve when turning elbows and gas line to prevent damage to the gas control valve and furnace. Left Side Gas Entry C8MP) (See Figure 16) Pipe can be run directly to gas valve through the hole provided in the left side of the cabinet. Right Side Gas Entry C8MP) (See Figure 16) Two (2) 90 ° street elbows or two (2) 90 ° standard elbows and two (2) close nipples are required for right side gas supply,. 441 01 2613 02 [_ 2. Follow steps 2 through 4 Piping with Street Elbows. Typical Gas Piping ('aMP) 25-25-02 Piping with Street Elbows 1. Screw one elbow onto gas valve with the outlet facing away from the furnace. 2. Screw second elbow onto first elbow tight enough to be leak proof. An additional 1/4 turn will be required at the end of step 2. See Figure 17 and Figure 18. Gas Valve with Elbows ('8MP) 25-25-03 iiiiiiiiiiiiiiiiiiiiiiiiI i:iiiiiiiiiii::::::;iiiiiiii!;!!i!!!!!i!!!!!!i!iiiiiiiiiiiiiill Gas Valve with Elbows (_8MP) 3. Gas supply line then can be run directly into opening of elbow. Piping with Close Nipples and Standard Elbows 1. Assemble elbows and nipples similar to street elbows shown in Figure 13. FIRE OR EXPLOSION HAZARD. Failure to properly install metal gas connector could result in death, personal injury and/or property damage. A flexible corrugated metal gas connector must be properly installed, shall not extend through the side of the furnace, and shall not be used inside the furnace. Black iron pipe shall be installed at the furnace gas control valve and extend a minimum of 2" outside furnace. Additional LP Piping Requirements • Have a licensed LP gas dealer make all connections at storage tank and check all connections from tank to furnace. • If copper tubing is used, it MUST comply with limitation set in Local Codes, or in the absence of local codes, the gas codes of the country having jurisdiction. • Two-stage regulation of LP gas is recommended. FIRE OR EXPLOSION HAZARD. An open flame or spark could result in death, personal injury and/or property damage. Liquefied petroleum (LP) gas is heavier than air and will settle and remain in low areas and open depressions. Thoroughly ventilate area and dissipate gas. Do NOT use a match or open flame to test for leaks, or attempt to start up furnace before thoroughly ventilating area. Final Check • Test all pipe for leaks. • If orifices were changed, make sure they are checked for leaks. During pressure testing of gas supply piping system: a. If test pressure does not exceed 1/2" psi, isolate the furnace from the gas supply piping system by closing the equipment shutoff valve. b. If test pressure exceeds 1/2" psi, the furnace and its manual equipment shutoff valve must be disconnected from the gas supply piping system. To check for leaks apply soap suds or a liquid detergent to each joint. Bubbles forming indicate a leak. Do not use an open flame to test for gas leaks. Fire or explosion could occur. • Correct even the smallest leak at once. _] 441 01 2613 02 9. Electrical Wiring ELECTRICALSHOCK HAZARD. Failure to follow safety warnings exactly could result in death or personal injury. Turn OFF electrical power at fuse box or service panel before making any electrical connections and ensure a proper ground connection is made before connecting line voltage. Power Supply Wiring The furnace MUST be electrically wired and grounded in accordance with local codes, or in the absence of local codes, with the National Electrical Code (NEC), ANSI/NFPA 70-2002 in the U.S., or the Canadian Electrical Code (CEC), CSA C22.1 in Canada. The power supply to the furnace connections must be between 104 VAC and 127 VAC during furnace operation for a...
