Anleitung Zusammenfassung


2E. Gas Supply and Piping 2E-1. General Instructions Review the following general instructions before continuing the installation. WARNING Do not convert this heater from natural gas to propane gas, or propane to natural. Field conversion could create carbon monoxide gas which can cause property damage, serious injury, or death. 1. Gas piping installation must be in accordance with the latest edition of ANSI Z223.1. In Canada, the installation must be in accordance with CAN- B149.1 or .2 and all local codes that apply. 2. Check the rating plate to make sure the heater is fitted for the type of gas being used. Teledyne Laars heaters shipped from the factory are certified to operate at an altitude of 0 to 2000 feet (0 to 609 m), or if so ordered, at higher altitudes. In the United States, the heater manifold is marked with a tag or sticker indicating one of the following high altitude operation codes: a. High altitude (H) - 2,000 to 6,000 feet (609 to 1829 m) b. High altitude (J) - 6,000 to 10,000 feet (609 to 3048 m) 3. In Canada, the heater rating plate is marked for specific altitude requirements: high altitude (H) is 2,000 to 4,500 feet (609 to 1372 m) above sea level. 4. Use the figures in Table 3 to size the gas inlet piping from the gas meter to the heater. Check all local codes for compliance before installing the heater. Manual Shutoff Valve Gas Supply Inlet To Equipment Inlet Union Cap T-Fitting 3" Min. Nipple Figure 5. The proper design for a sediment trap / drip leg. 5. Install a sediment trap (drip leg) ahead of the gas controls (see Figure 5). Fit the trap with a threaded cap which can be removed for cleaning. 6. Install a manual gas shutoff valve for service and safety. Do not use a restrictive gas cock. DO NOT USE GAS FLEXIBLE PIPING. 7. Disconnect the heater and its individual shutoff valve from the gas supply system during pressure testing of the system at pressures higher than 1/2 pounds per square inch (psi) (3.45 kilopascals [kPa]). If the test pressure is equal to or less than 1/2 psi (3.45 kPa), close the manual shutoff valve on the heater during the piping pressure test. Table 3.

These numbers are for natural gas (0.65 Sp. Gr.) and are based on 1/2 inch (13 mm) water column pressure drop. Check supply pressure with a manometer, and local code requirements for variations. For liquefied petroleum gas, reduce pipe diameter one size, but maintain a 3/4 inch (13 mm) minimum diameter. 2. Check supply pressure and local code requirements before preceding with work....
