If it isn’t, donot connect the boiler/water heater to the gassupply. Gas supply piping must be in accordancewith the National Fuel Code, ANSI Z223.1-latestrevision or applicable provisions of the localbuilding codes. Canadian Installations mustcomply with CAN/CGA B149.1 or .2 InstallationCode. Failure to comply with this warning canresult in extensive property damage, severepersonal injury or death!The Spectrum boiler/water heaters come from thefactory ready to be piped to the gas supply. If for anyreason the boiler/water heater is not for the type of gasavailable at the installation site, call the nearest RBIrepresentative to resolve the problem.NOTE: A minimum gas supply pressure of 5 in,127 mm W.C. natural or 12 in, 305 mm W.C. propaneand maximum gas supply pressure of 14 in,356 mm W.C. natual or propane, must be availableat the safety shutoff valve inlet with the unit(s)operating.Table 10 should be used to ensure that the gas supplypiping is sized properly. If more than one appliance issupplied by the same supply pipe, the piping must besized based on the maximum possible demand. Do notneglect the pressure drop due to pipe fi ttings. Table 10should be used in conjunction with Table 11 to ensurethat the gas supply piping has the capacity to meet thedemand.301522855908901650270047009700Maximum gas volume of pipe, (ft 3/hr)Pipe length in feetTable 10 - Gas Pipe CapacityNominalIron PipeSize, (in)Maximum pipe capacity in ft3 /hr based on 0.60 specifi c gravity gasat a pressure of 0.5 psig or less and a 0.3" W.C. pressure drop.50115215440670127020003600740060105195400610115018503250680080901703505309901600280058001007915030546087014002500510015064120250380710113020004100Note: Multiply the gas volume by 0.62 for propane fl ow capacity in ft3 /hr.Multiply the propane fl ow capacity by 2500 Btu/ft3 to determine the propane Btu/hrcapacity for a given pipe size and length.Figure 10 depicts the proper way to connect theboiler/water heater to the gas supply piping. The manualshut-off valve MUST be installed in the supply piping. Itshould be installed 5 ft, 1.5 m above the fl oor whererequired by local codes. Provide a sediment trap at thebottom of the vertical section of the gas supply pipeupstream of the gas controls.A ground joint union should be installed between theboiler gas controls and the supply piping. Each of theseitems are needed to ensure long life and ease ofservicing. Always use a pipe sealant that is suitable foruse with LP gas.Figure 10 - Gas Supply PipingCAUTION: Always use a wrench on the gas valvebody when making gas connections to it. Neverover-tighten the piping entering the gas valve bodyor gas valve failure may result!Equivalent of pipe length (ft)NominalIron PipeSize, (in)GasCock 2GateValve 2Tee190°ElbowType of pipe fi tting1"1 1/4"1 1/2"2"2 1/2"3"4"5.26.98.010.312.315.315.30.60.80.91.21.41.81.81.51.92.33.03.74.54.5Notes: 1.
