Trinity │Installation and Operation Instructions Ti Series206.0 INSTALLING GAS PIPINGThe Trinity Ti is factory equipped to operate with Natural Gas, the installation of a conversion kit isrequired prior to operating with Propane Gas. The Natural to LP Conversion Kit must be installed priorto installing the gas piping to the appliance. Failure to properly convert the unit to operate with Propane may result in propertydamage, serious injury or death.Liquefied Petroleum (LP)propane gas is heavier than air;therefore, it is imperative that your appliance is notinstalled in a pit or similar location that will permit heavierthan air gas to collect. Check with Local Codes as theymay require appliances fueled with LP gas be providedwith an approved means of removing unburned gases fromthe room. Failure to follow these instructions may result inserious injury or death.InstallationRefer to the current National Fuel Gas Code ANSIZ223.1/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 using approvedflexible gas piping (if acceptable by local codes) to connect the appliance to the gas supply (See Figure 6-1 for details). You plan the installation so that the piping does not interfere with the vent pipe, or the removal of the valve, burner, andserviceable 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 pressure should occur whenany 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 sparingly to all malethreads, starting at two threads from the end. Over doping or applying dope to the female end, can result in a blocked gasline. DO NOT TIGHTEN FITTINGS WITHOUT SUPPORTING THE GAS VALVE as damage to the valve or blower motorcan occur. Install a manual “Equipment Shut-Off Valve” as shown in Figure 6-1. Valve must be listed by a nationally recognizedtesting lab. The gas line piping can safely be removed from the appliance for servicing, by strategically placing the gas line shutoff andunion; see example in Figure 6-1. All gas piping, including gas components in the appliance, are checked for leaks using a “Bubble Test”, prior to operatingthe appliance.Strain on the gas valve and fittings may result in vibration, premature component failure and leakageand may result in a fire, explosion, property damage, serious injury or death.Flexible gas piping cannot be used within the appliance cabinet and cannot pass through the cabinetwall, use rigid piping as shown in Figure 6-1. Failure to follow these instructions may result in fire,property damage, serious injury or death.Do not use an open flame to test for gas leaks. Failure to follow these instructions may result in fire,property damage, serious injury or death .When performing a pressure test on the gas line piping, be sure the appliance is disconnected or isolatedif the test pressure is expected to exceed 1/2 PSI (14” w.c.), as damage to the valve could occurresulting in fire, property damage, serious injury or death.It is highly recommended to useflexible gas pipe, the gas valve andblower cannot support the weight ofpiping. If piping is used, ensure thatthe valve supports NO WEIGHTGas cock shut OffValve to be "T"type handleFigure 6-1 Gas Connection
