Anleitung Zusammenfassung


A licensed propane installer must make all LP gas connections. Improper gas connections could result in a fire or an explosion! The GV100W hot water boiler comes from the factory ready to be piped to the gas supply. WARNING: Check the boiler rating plate and make sure that the boiler is for the type of gas that will be used. If it isn’t Do not connect the boiler to the gas supply or a fire or an explosion may occur! If for any reason the boiler is not for the type of gas available at the installation site, call the nearest Smith Cast Iron Boiler distributor to resolve the problem. FIG. NO. 12 depicts the proper way to connect the boiler to the gas supply piping. The manual shut-off valve MUST be installed in the supply piping. It should be approximately 5 ft, 1.5m, above the floor. Provide a sediment trap/ drip leg at the bottom of the vertical section of the gas supply pipe. A ground joint union should be installed between the boiler gas controls and the supply piping. Each of these items are needed to ensure long life and ease of servicing. Always use a pipe sealant that is suitable for use with LP gas. CAUTION: Always use a wrench on the gas valve body when making gas connections to it. Never over-tighten the piping entering the gas valve body. Failure to comply with this caution may result in gas valve failure! FIG. NO. 12 Gas Supply Piping GAS INLET INSTALL MANUAL SHUT-OFF VALVE GAS SUPPLY 5 FT. ABOVE FLOOR PIPING WHERE REQUIRED BY LOCAL CODES GROUND JOINT UNION SEDIMENT TRAP OR DRIP LEG TO (TO EXTEND TO FLOOR) BOILER FLOOR LEVEL ........... ........... Table 3 should be used to ensure that the gas supply piping is sized properly. If more than one appliance is supplied by the same supply pipe, the piping must be sized based on the maximum possible demand. Do not neglect the pressure drop due to pipe fittings. Table 4 should be used in conjunction with Table 3 to ensure that the gas supply piping is sized properly. Safe lighting and other performance criteria were met with the gas manifold and control assembly provided on the boiler when the boiler underwent tests specified in ANSI Z21.13/CAN 4.9. All gas connections must be leak tested before putting the boiler into operation. WARNING: Never use an open flame to test for gas leaks. Always use an approved leak detection method. Failure to comply with this warning could result in an explosion! Whenever the gas supply piping is pressure tested the boiler gas controls must be protected. If the test pressure is equal to, or less than 1/2 psig, 3.5 kPa, isolate the boiler by closing it’s manual shut off valve, see FIG. NO. 8. If the test pressure is greater than 1/2 psig 3.5 kPa, disconnect the boiler and it’s individual shut-off valve from the gas supply piping.

Des erreurs de cablage peuvent entrainer un fonctionnement in-adequat et dangereux. S’assurer que l’appareil fonc-tionne adequatement une fois l’entretirn termine. The electrical connections to this boiler must be made in accordance with all applicable local codes and the latest edition of the National Electrical Code, ANSI/NFPA-70. Installation should also conform with CSA C22.1 Canadian Electrical Code Part I if installed in Canada. Install a separate 120 volt 15 amp circuit for the boiler. A shut-off switch should be located at the boiler. The boilermust be grounded in accordance with the authority having jurisdiction, or if none, the latest edition of the National Electrical Code, ANSI/NFPA-70. Line voltage field wiring of controls and other devices must conform to the temperature limitation of type T wire at 95°F, 35°C, above room temperature. Use copper conductors with a minimum size of #14 awg. Low voltage wiring must not be less than #18 awg with a neoprene, thermoplastic or other equivalent insulation having a minimum insulation thickness of 0.012 in, 0.3 mm. ...
