Trinity Lx │Installation and Operation Instructions Lx Series347.0 INSTALLING GAS PIPINGThe Trinity Lx is factory equipped to operate with Natural Gas, the installation of aconversion kit is required prior to operating with Propane Gas. The Natural to LPConversion Kit (see Table 7-1) must be installed prior to installing the gas piping to the appliance. Failure toproperly convert the unit to operate with Propane may result in property damage, serious injury or death.Liquefied Petroleum (LP) propane gas is heavier than air. Do not install the appliance ina pit or similar location that will permit heavier than air gas to collect. Check with LocalCodes as they may require appliances fueled with LP gas be provided with an approved means of removingunburned gases from the room. Failure to follow these instructions may result in serious injury or death.Table 7-1 Natural Gas to LP Propane Conversion KitSeries Model Kit NumberTrinity Lx 150, 150E, 200, 300 82650-1Trinity Lx 400 83017-1Trinity Lx 500 84386-1General Notes:Lx600-800 - Do not convert to propane. Use Natural Gas only.InstallationRefer to the current National Fuel Gas Code ANSI Z223.1/NFPA 54 or CAN/CGA B149.1 installation codes,and local codes for gas piping requirements and sizing. Pipe size running to the unit depends on:• Length of pipe.• Number of fittings.• Type of gas.• Maximum input requirement of all gas appliances in the residence.Ensure that:• The gas line connection to the appliance does not apply any weight to the gas valve. NTI recommends usingapproved flexible gas piping (if acceptable by local codes) to connect the appliance to the gas supply (SeeFigure 7-1 for details).• You plan the installation so that the piping does not interfere with the vent pipe, or the removal of the valve,burner, and serviceable components.• The Appliance shall be installed such that the gas ignition system components are protected from water(dripping, spraying, rain etc.) during installation and servicing.• The gas piping is large enough for all the appliances in the home. No appreciable drop in line pressureshould occur when any unit (or combination of units) lights or runs. Use common gas-line sizing practices.• Always use a pipe-threading compound that is resistant to propane (LP) gas solvent action. Apply sparinglyto all male threads, starting at two threads from the end. Over doping or applying dope to the female end,can result in a blocked gas line.• DO NOT TIGHTEN FITTINGS WITHOUT SUPPORTING THE GAS VALVE as damage to the gas valveor combustion blower can occur.• Install a manual “Equipment Shut-Off Valve” as shown in Figure 7-1. Valve must be listed by a nationallyrecognized testing lab.• The gas line piping can safely be removed from the appliance for servicing, by strategically placing the gasline shutoff and union; see example in Figure 7-1.• All gas piping, including gas components in the appliance, are checked for leaks using a “Bubble Test”,prior to operating the appliance.
